Cloud Atlas activity in the second half of 2025 and early 2026: new tools and a new payload


The media in this post is not displayed to visitors. To view it, please log in.

In 2025, we observed pervasive SSH tunnel activity, which has remained active into 2026, affecting many government organizations and commercial companies in Russia and Belarus. Behind some of this activity is Cloud Atlas, a group we have known since 2014. During our investigation, we identified new tools used by this group, as well as indicators of compromise.

The group is back to sending out archives containing malicious shortcuts that launch PowerShell scripts. This technique is employed in addition to the previously described use of malicious documents, which exploit an old vulnerability in the Microsoft Office Equation Editor process (CVE-2018-0802) to download and execute malicious code. We have observed the use of third-party public utilities (Tor/SSH/RevSocks) to gain a foothold in infected systems and create additional backup control channels.

Technical details

Initial infection


As for the primary compromise, Cloud Atlas remains consistent in using phishing. In the observed campaigns, the attackers emailed a ZIP archive containing an LNK file as an attachment.

Actions performed by the downloaded PowerShell:

StepActionDescription
1 Drops “$temp\fixed.ps1”Pre-staging: places the main payload locally in advance to ensure an execution capability independent of subsequent network connectivity or C2 availability.
2Creates “Run” registry key “YandexBrowser_setup” for “$temp\fixed.ps1” startup
Early persistence: guarantees execution upon the next logon or reboot. If the script is interrupted during later stages, the payload will still activate automatically.
3Downloads and drops “$temp\rar.zip”
Extracts “*.pdf” from the downloaded “$temp\rar.zip”
Payload delivery: retrieves the decoy archive from the remote server to prepare user-facing content for the distraction phase.
4Extracts “*.pdf” from the downloaded “$temp\rar.zip”Decoy preparation: unpacks the legitimate-looking document so it can be executed silently without requiring user interaction.
6Opens extracted decoy document “*.pdf” with user’s default softwareUser distraction: opens a convincing document to maintain user engagement and creates a legitimate workflow appearance to buy additional 30–120 seconds for background operations.
6Executes “taskkill.exe /F /Im winrar.exe”Process concealment: terminates the archive extractor to prevent the user from seeing the archive contents or noticing unexpected file extraction activity.
7Searches and deletes “rar.zip”, “*.pdf.zip” and “*.pdf.lnk”Anti-forensic cleanup: removes the initial infection artifacts before activating the main payload, reducing the number of disk traces available for incident response or EDR correlation.
8Executes “$temp\fixed.ps1”Controlled execution: launches the main payload only after persistence is secured, the user is distracted, and access traces are cleaned up.
Fixed.ps1 (loader)


The primary purpose of the Fixed.ps1 script is to deliver and install subsequent malware onto the compromised system, specifically VBCloud and PowerShower. Fixed.ps1 establishes persistence (by adding itself to registry Run keys), creates a decoy for the user (by opening a PDF document), and executes the next stages of the attack.

Fixed.ps1::Payload (VBCloud dropper)


Example of the fixed.ps1::Payload (VBCloud dropper)
Example of the fixed.ps1::Payload (VBCloud dropper)

This module functions as a dropper for the VBCloud backdoor. It drops two files onto the infected machine:

  • video.vbs: the loader of the backdoor,VBCloud::Launcher. This is a VBScript that decrypts the contents of video.mds (typically using RC4 with a hardcoded key) and executes it in memory.
  • video.mds: the encrypted body of the backdoor, VBCloud::Backdoor. This is the main module that connects to a C2 server to receive additional scripts or execute built-in commands. This backdoor is designed to function as a stealer, specifically targeting files with extensions of interest (such as DOC, PDF, XLS) and exfiltrating them.


Fixed.ps1::Payload (PowerShower)


This module installs a second backdoor called PowerShower on the system. We don’t have the specific script that performs this installation, but we assume it’s performed by a script similar to fixed.ps1::Payload (VBCloud dropper).

Unlike VBCloud, which focuses on file theft, PowerShower is primarily used for network reconnaissance and lateral movement within the victim’s infrastructure. PowerShower can perform the following tasks:

  • Collect information about running processes, administrator groups, and domain controllers.
  • Download and execute PowerShell scripts from the C2 server.
  • Conduct “Kerberoasting” attacks (stealing password hashes of Active Directory accounts).

PowerShower is dropped onto the system via the path ‘C:\Users\[username]\Pictures\googleearth.ps1’.

Contents of the googleearth.ps1(PowerShower)
Contents of the googleearth.ps1(PowerShower)

PowerShower::Payload (credential grabber)


PowerShower downloads an additional script for stealing credentials. It performs the following actions:

  • Creates a Volume Shadow Copy of the C:\ drive.
  • Copies the SAM (stores local user password hashes) and SECURITY system files from this shadow copy to C:\Users\Public\Documents\, disguising them as PDF files.
  • The script is launched in several stages. To execute with high privileges, the script uses a UAC bypass technique via fodhelper.exe (a built-in Windows utility). This allows PowerShell to run as an administrator without directly prompting the user, which could otherwise raise suspicion.

The full launch chain looks like this:

The full Base64-decoded script is given below.


Multi-user RDP by patching termsrv.dll


Moving laterally across the victim’s network, the attackers executed a suspicious PowerShell script named rdp_new.ps1 (MD5 1A11B26DD0261EF27A112CE8B361C247):

The script is designed to allow multiple RDP sessions in Windows 10 by patching the termsrv.dll file. Termsrv.dll is the core Windows library that enforces Remote Desktop Services rules.

By default, Windows limits the number of simultaneous RDP sessions. Removing this restriction allows attackers to operate on the machine in the background without disconnecting the legitimate user, thereby reducing the likelihood of detection.

At first, the script enables RDP on the firewall and downgrades the RDP security settings:

Before modifying termsrv.dll, the script takes ownership and assigns itself full permissions. Then the script finds the sequence of bytes 39 81 3C 06 00 00 ?? ?? ?? ?? ?? ?? and replaces it with B8 00 01 00 00 89 81 38 06 00 00 90. After these manipulations, the script restarts the RDP service.

Example of script

The patched version allows multiple concurrent logins so attackers can stay connected without disrupting the legitimate user, thereby reducing suspicion.

Reverse SSH tunneling


As mentioned above, during this wave of attacks, the adversaries widely deployed reverse SSH tunnels to many hosts of interest. The compromised machine initiates an SSH connection to an attacker-controlled server, which allows attackers to bypass standard firewall rules via establishing outbound connections.

That way, even if the primary backdoor is discovered, the attackers can maintain control through the SSH tunnel.

To install a reverse SSH tunnel on a victim’s host, the attackers run VBS scripts via PAExec or PsExec.

We’ve seen three types of scripts:

  • Gen.vbs (WriteToSchedulerGenerateKey.vbs) generates key for SSH tunnel.
  • Run.vbs (WriteToSchedulerRunSSH.vbs) runs reverse SSH tunnel.
  • Kill.vbs (WriteToSchedulerKillSSH.vbs) stops reverse SSH tunnel via taskkill.exe.

To achieve persistence, the attackers added a new scheduled task in Windows:

In some cases, before establishing a reverse SSH tunnel, attackers set new access permissions to the folder containing the private key to prevent the legitimate user or system administrators from easily accessing or modifying it:


Patched OpenSSH


Some OpenSSH binaries used by the attackers had their imports modified. Instead of libcrypto.dll, the SSH executable imports syruntime.dll, which was placed in the same folder as the binary. This was likely done to evade detection and ensure stealth.

In addition, we found a portable version of OpenSSH, presumably compiled by the adversaries:


RevSocks


In addition to Reverse SSH tunnels, the attackers installed RevSocks using the same infrastructure. RevSocks is an alternative tool to SSH for establishing tunnels and proxy connections, written in Golang. This tool allows direct connection to workstations on the local network. It also allows attackers to gain access to other segments of the victim’s network by using the machine as a gateway. In some cases, C2 addresses were hardcoded into the binary; in other cases, the C2 was passed in command line arguments.

There were also reverse SOCKS samples with hardcoded C2 addresses:


Tor tunneling


To maintain control over the compromised host, the Tor network was used in some cases. A minimal set of a Tor executable and configuration files, necessary for launching HiddenService, was copied to the system directories of infected devices. The name of the Tor Browser executable file was modified. As a result, the infected machine was accessible via RDP from the Tor network when accessing the generated .onion domain.
Below is an example of a configuration file for routing connections from Tor to RDP ports on the local network, as well as example command lines for logging into Tor.

Example of TOR configuration file
Example of TOR configuration file

PowerCloud


We analyzed a new Cloud Atlas tool, PowerCloud. It collects user data with administrator privileges and writes this information to Google Sheets in Base64 format.

The tool represents an obfuscated PowerShell script. In most cases, it is packaged into an executable file using the PS2EXE utility, but we have also encountered variants in the form of a separate PowerShell script.

To find administrators on the victim host, the tool executes the following command:

This information is appended with the computer name and current date, the data is encoded in base64, and then the collected data is added to an existing Google Sheet.

Browser checker


Additionally, the attackers used another PowerShell script (MD5 5329F7BFF9D0D5DB28821B86C26D628F), compiled into an executable file via PS2EXE, which checks whether browser processes (Chrome, Edge, Firefox, and other) are running. This helps detect when the user is working on the computer. This can be used to choose the optimal time for conducting attacks (for example, when the user is away but their browser is still open) or simply to gather information about the victim’s habits.

The information about running browsers is written to a log file on the local host.

Victims


According to our telemetry, in late 2025 and early 2026, the identified targets of the described malicious activities are located in Russia and Belarus. The targeted industries mostly include government agencies and diplomatic entities.

We attribute the activity described in this report to the Cloud Atlas APT group with a high degree of confidence. The group used techniques and tools described previously, such as the initial access vector, the Python script for information gathering, and the Tor application for forwarding ports to the Tor network. The victim profile and geography also matches the Cloud Atlas targets.

We couldn’t help but notice some parallels with recent Head Mare activity. The PhantomHeart backdoor (available in Russian only), attributed to Head Mare and used to create an SSH tunnel, was placed in directories actively used by Cloud Atlas:

  • C:\Windows\ime
  • C:\Windows\System32\ime
  • C:\Windows\pla
  • C:\Windows\inf
  • C:\Windows\migration
  • C:\Windows\System32\timecontrolsvc
  • C:\Windows\SKB

However, TTPs are still differentiated.

Conclusion


For more than ten years, the Cloud Atlas group has continued its activities and expanded its arsenal. Over the course of last year, many targeted campaigns in general were found to employ ReverseSocks, SSH and Tor, and the use of these utilities was no exception for Cloud Atlas. Creating such backup control channels using publicly available utilities significantly complicates the complete disruption of attackers’ actions on compromised systems. We will continue to closely monitor the group’s activity and describe their new tools and techniques.

Jacket Turned Cyberpunk Wearable OLED Display


The media in this post is not displayed to visitors. To view it, please log in.

If you’ve played Cyberpunk 2077, you might have seen the rad jacket that has a screen in the collar. Once upon a time, such a thing would be solely the preserve of science fiction—you certainly wouldn’t be achieving that look with cathode ray tubes, that much is for sure. However, technology has advanced to the point where [Zibartas] was able to produce just such a jacket in real life.

The key to the build is the advent of the flexible OLED screen. [Zibartas] was able to source four such panels in a smartphone-like aspect ratio, which came in at the hefty price of $300 each. Two Raspberry Pi 4s were enlisted to drive two screens each. The older model Pi was chosen as it was capable of achieving a neat hack to better play smooth video across two displays. A rudimentary sync system was whipped up using GPIO pins to keep video from both Pis playing together. From there, it was simply a matter of figuring out how to create a structure to hold the screens within the large collar of the scratch built cyberpunk-styled jacket. As it turns out they don’t actually flex much in the final install, as they’re held in a 3D printed structure to keep them safe from damage.

The final result is quite something, very accurately recreating the jacket from the game itself. While technically a simple build, actually pulling it off required some delicate work and smart design decisions to make it practical to wear. We’ve featured some other fun jackets over the years, too.

Making a PCB The Old-Fashioned Way


The media in this post is not displayed to visitors. To view it, please log in.

A desk fan with an air filter. On the side, the final assembled PCB is visible.

Nearly all modern PCBs are designed with the help of EDA software, but not all of them. [ALTco] shows us the process of plotting out a board the old-fashioned way — by hand.

Back in the day, drawing out the traces on a PCB lead to beautiful, smooth lines that [ALTco] wanted to imitate. But first, he needed to figure out how the rest of the fabrication process worked. He starts by just experimenting, both with the “resist” markers and paint, and the etching compound. Things rarely work first-try, and neither did his home-made etchant. So then it was time to buy some ferric chloride, the standard copper etchant for PBCs. A few more tests sorted out which permanent marker worked best.

[ALTco] starts by thoroughly cleaning a raw copper-clad board so the marker sticks properly, then draws the circuit for a little analog fan controller. The board is then laid in a bath of the etchant for several minutes while gently rocking it to keep the reaction going. Finally the board is taken out, etchant stored for re-use, and the board washed with water and then presumably IPA to remove the remaining marker. Some assembly of the newly-printed circuit board later and you have a cute little smoke absorber for your soldering projects.

Get That Windows 7 Feel In An OS That Still Gets Updates


The media in this post is not displayed to visitors. To view it, please log in.

Do you want to go back to an era when Windows was… simpler? Back when things worked, before the AI and the bloat took over your hard drive and RAM space in equal measure? You might like to give Classic 7 a spin (via The Register).

From the drop, we should state that Classic 7 is not Windows 7 at all. Instead, it’s a reskin of Windows 10, specifically, the IoT Enterprise LTSC version. This is a particularly attractive version of Windows 10, as Microsoft has promised long-term support in terms of security updates until 2032. It also strips out annoying consumer-focused bloat like the Xbox gaming overlay and Cortana, and it eliminates forced feature updates that have become the norm in modern Windows installs. Combine all those niceties with the clean and simple feel of the recreated Windows 7 interface, and you have a beautiful operating system that has everything you need and nothing you don’t.

There are, of course, some hurdles to jump over; you’d need to find an appropriate license for this version of Windows and all that jazz. But if you long for the days before Microsoft so cruelly eviscerated the Start Menu and started making everything worse, you might find that Classic 7 is for you.

E-Fortune Cookie Will Humble, But Never Crumble


The media in this post is not displayed to visitors. To view it, please log in.

A tiny, rectangular, 3D-printed box with an e-paper display and a fortune cookie design beneath it. The fortune reads: "Your next firmware update will both solve and create problems."

Will your next project be a success? Only time will tell, but if you build [gokux]’s tiny ESP32 fortune cookie, we predict that, at the very least, there won’t be any crumbs involved.

After briefly entertaining the idea of shoving an ESP32 in a standard fortune cookie, [gokux] thought better of it and came up with this instead. Once shaken, this small gadget displays a fortune on its e-paper screen. It can store over 3,000 fortunes and works entirely offline, so you’re never without an oracle.

Inside you’ll find a Seeed Xiao ESP32-S3 Plus and a matching e-paper display board. [gokux] is detecting the shakes with an MPU-6050 accelerometer, and powers everything with a small Li-Po pouch.

If you tire of the fortunes that shake out, the small buttons on the left side will get you into the other modes, which are a dice roller and a coin flipper. Again, you just shake the thing until you get what you want. Be sure to check it out in the video after the break.

Want to know how an MPU-6050 works, and what it looks like under the hood? Yeah, we thought so.

Sliding-Screen Cyberdeck Has Chunky, Rugged Design


The media in this post is not displayed to visitors. To view it, please log in.

[Jankbu] needed a new computer, but had little interest in purchasing a modern laptop off the shelf. Instead, it was time to build a cyberdeck with a neat modular design to suit his exact needs.

The heart of the build is a Raspberry Pi 5, which provides a good amount of computing power for regular tasks. It’s wrapped up in a 3D-printed enclosure with rail mounts on the back, along with a NOS 450 TKL mechanical keyboard, offering full-travel keys in a compact layout. The 10.1″ IPS touchscreen display is mounted on sliding rails to cover the keyboard when it’s not needed. A smattering of buttons live around the screen, in a manner akin to so many industrial controllers. On either side, the deck has large grab handles, with one side featuring custom horizontal and vertical scroll controls, while the other rocks a trackball. Power is via NP-F batteries, which are more commonly used to run Sony camcorders.

Unlike so many cyberdecks, [Jankbu] didn’t just build the device to look cool—it also serves a practical purpose. It’s great for running Freecad, and the rail mounts on the rear make it perfect for mounting around the workshop during a job as needed. Files are on Github for those eager to learn more.

What’s fun about this build is that it’s not just a show piece, it’s something that gets used every day. That’s a testament to [Jankbu’s] well-reasoned design, that considered what the device was for before it was put together. We’ve featured plenty of other fantastic cyberdecks in the past, too.

Why the Smart Home Bubble Popped


The media in this post is not displayed to visitors. To view it, please log in.

Circa 2015 or so, it seemed like you couldn’t move a finger without being bombarded with ads and articles about ‘smart homes’ and the ‘internet of things’ — all of which would make our lives so much easier and more automated. Fast-forward a decade and this dream has mostly evaporated along with many of the players in the space. Why this happened is the topic of a recent video by [Caya].

An interesting bit of context that the video starts off with is that home automation really kicked off back in 1975, when the X10 protocol and related devices using power lines for signaling began being sold. These fully integrated solutions generally worked reasonably well, but what all changed when the IoT and ‘smart home’ craze kicked off and brought with it an explosion of new standards.

Over the past decade we have seen the concept of a ‘smart home’ collapse into a nightmare of abandoned IoT devices, subscription services, forced ads, privacy violations, and an increasingly more congested 2.4 GHz spectrum that everything from WiFi and Zigbee to Bluetooth and others ended up competing for, with a corresponding collapse in reliability of data transmissions.

As raised in the video, a big issue is that of the financial viability of running the remote services for a smart home solution, even if this is the part that should make it as plug-and-play as a 1990s-era smart home solution. To the average user setting up their own locally hosted smart home solution isn’t really a straightforward option.

Although at the end [Caya] demonstrates using Home Assistant (HA) as a locally hosted alternative, this is still not something that a non-techie will be able to set up or maintain. Even if you shell out a cool two-hundred clams for the Home Assistant Green plug-and-play hardware solution, the average person will be lost the second any of the prescribed steps in provided documentation do not work. Woe to whoever is the person who is ‘good with computers’ in those cases.

Ultimately another problem with ‘smart homes’ is that they’re really not that smart, as you can definitely set up all kinds of rules in HA and similar solutions, but this is more painstaking manual automation with all the excitement of programming PID controllers. Having an actual intelligence behind the system that could react to what’s happening would make it a far easier sell, yet which is where all the ‘smart assistants’ like Alexa keep falling flat.

Currently [Caya] has set up his HA-based lighting configuration to be used by OpenClaw ‘agentic AI’, as a way to add some actual ‘smarts’, but it’s telling that he hasn’t integrated the smart lock of his apartment into the system yet. Nobody wants to have the OpenClaw agent tell you that it ‘cannot open the front door’ for you, after all.

Exchange Online Writeback: sincronizzare le modifiche cloud con Active Directory on-premises


Il problema storico degli ambienti ibridi Exchange


Chiunque abbia gestito un ambiente ibrido Exchange-Active Directory conosce bene il dolore: le caselle email esistono su Exchange Online, ma gli attributi che le descrivono — indirizzi proxy, parametri di routing, configurazioni di delivery — devono essere sempre sincronizzati con l’Active Directory on-premises. Le applicazioni line-of-business leggono questi dati direttamente dall’AD locale, e se Exchange Online e l’AD si disallineano, iniziano i problemi: email che non arrivano, rubriche inconsistenti, applicazioni interne che non trovano gli indirizzi corretti.

Fino ad oggi, la soluzione era mantenere almeno un server Exchange on-premises solo per gestire questo ciclo di scrittura degli attributi. Un server costoso da mantenere, aggiornare e mettere in sicurezza, la cui unica ragione di esistere era permettere la modifica degli attributi Exchange nell’Active Directory locale. Microsoft lo aveva già ammesso esplicitamente: il percorso verso l’abbandono dell’ultimo Exchange server on-premises era bloccato proprio da questo nodo tecnico.

Con la public preview del Writeback per Cloud-Managed Remote Mailboxes, annunciata a maggio 2026, questo nodo comincia finalmente a sciogliersi.

Cosa cambia con il Writeback di Exchange Online


La nuova funzionalità consente a Exchange Online di sincronizzare automaticamente le modifiche agli attributi Exchange dalla cloud verso l’Active Directory on-premises, invertendo il flusso tradizionale. Finora la sincronizzazione era unidirezionale: dall’AD locale verso Exchange Online, gestita da Microsoft Entra Connect Sync (o dal predecessore Azure AD Connect). Ora, con il writeback abilitato, qualsiasi modifica apportata a un mailbox cloud-managed — un nuovo indirizzo proxy, una modifica al display name Exchange, una variazione nei parametri di routing — viene automaticamente propagata all’AD on-premises tramite Microsoft Entra Cloud Sync.

Il risultato pratico è che l’AD locale rimane sempre aggiornato, e le applicazioni on-premises che leggono direttamente gli attributi Exchange dall’AD continuano a funzionare correttamente — anche dopo aver spostato la gestione delle mailbox completamente nel cloud.

Architettura della soluzione


Il writeback utilizza Microsoft Entra Cloud Sync come layer di trasporto tra Exchange Online e l’AD on-premises. Un aspetto importante da sottolineare: Entra Cloud Sync non sostituisce Entra Connect Sync. Le due soluzioni coesistono fianco a fianco. Le organizzazioni che usano già Entra Connect Sync per la sincronizzazione identità non devono disinstallare o sostituire nulla — installano semplicemente un agent Entra Cloud Sync aggiuntivo e configurano il nuovo flusso di writeback.

Il percorso di dati completo è quindi:

  1. L’amministratore modifica un attributo Exchange Online (es. aggiunge un alias email)
  2. Exchange Online propaga la modifica a Microsoft Entra ID
  3. Entra Cloud Sync rileva la modifica e la scrive nell’Active Directory on-premises
  4. Le applicazioni LOB leggono il dato aggiornato dall’AD locale in tempo reale


Come abilitare il Writeback: configurazione passo per passo


Il prerequisito fondamentale è avere almeno un agent Microsoft Entra Cloud Sync installato e configurato per il dominio AD target. Una volta soddisfatto questo requisito, la configurazione del writeback avviene dall’interfaccia di Entra ID:

Microsoft Entra Admin Center
→ Identity → Hybrid Management → Entra Connect
→ Cloud Sync → Configurations
→ New configuration → EXO to AD attribute sync (Preview)


Nella pagina di configurazione, si verifica che l’agent selezionato corrisponda al dominio corretto, quindi si conferma con Create. Dalla scheda Overview della nuova configurazione, si clicca Start provisioning per avviare il flusso di sincronizzazione.

Una volta avviato, il sistema inizia a monitorare le modifiche agli attributi Exchange nelle mailbox cloud-managed e a propagarle verso l’AD on-premises. Non è richiesta nessuna configurazione aggiuntiva sull’Exchange Server on-premises — anzi, questo è esattamente il punto: con questa funzionalità attiva, l’Exchange server locale non è più necessario per il writeback degli attributi.

Limiti della Preview e roadmap


La funzionalità è attualmente in Public Preview con alcune limitazioni da tenere presenti:

  • Limite di mailbox: Durante la preview il writeback supporta tenant con meno di 200.000 mailbox cloud-managed. Il limite verrà rimosso o aumentato alla General Availability.
  • GA target: Microsoft ha indicato la fine di giugno 2026 come obiettivo per la General Availability.
  • Attributi supportati: Il writeback copre gli attributi Exchange designati — indirizzi proxy, parametri di routing, attributi mail-related — non l’intera struttura dell’oggetto AD.


Implicazioni strategiche per i sysadmin


Questa funzionalità rappresenta un passo concreto verso quello che Microsoft chiama “Last Exchange Server Retirement” — la possibilità di eliminare definitivamente l’ultimo server Exchange on-premises dalle infrastrutture ibride senza perdere funzionalità critiche.

Per i team IT, significa valutare concretamente un percorso di dismissione hardware e software che finora era rimasto bloccato. Un server Exchange on-premises richiede licenze, hardware dedicato (o VM), aggiornamenti cumulativi, patching della sicurezza e competenze specializzate per la manutenzione. Eliminarlo non è solo un risparmio economico: riduce la superficie d’attacco e semplifica l’architettura complessiva.

Naturalmente, prima di pianificare la dismissione, è necessario verificare alcune condizioni:

  • Tutte le mailbox gestite on-premises devono essere migrate a Exchange Online come cloud-managed remote mailboxes
  • Le applicazioni LOB che leggono attributi Exchange dall’AD devono essere testate nel nuovo scenario di writeback
  • La latenza di sincronizzazione di Entra Cloud Sync deve essere compatibile con le esigenze delle applicazioni
  • I flussi di email che usano connettori on-premises devono essere valutati separatamente


Conclusione


Il writeback di Exchange Online verso Active Directory on-premises è una delle novità più rilevanti per i sysadmin che gestiscono ambienti Microsoft ibridi. Risolve un problema tecnico che aveva bloccato molte organizzazioni nella loro transizione al cloud-only per anni, togliendo l’ultimo alibi per mantenere un server Exchange on-premises attivo.

Il fatto che sia ancora in preview suggerisce di non pianificare dismissioni immediate, ma è il momento giusto per iniziare i test in ambienti non produttivi, validare la compatibilità con le applicazioni LOB e costruire il piano di migrazione. La GA prevista per fine giugno 2026 potrebbe arrivare in coincidenza con la scadenza dei certificati Secure Boot: due scadenze importanti da non ignorare nello stesso mese.

TeamPCP viola GitHub dall’interno: 3.800 repository sottratti in 18 minuti tramite un’estensione VS Code malevola

TeamPCP viola GitHub dall’interno: 3.800 repository sottratti in 18 minuti tramite un’estensione VS Code malevola


18 minuti. È il tempo in cui una versione trojanizzata dell’estensione VS Code Nx Console (nrwl.angular-console) è rimasta disponibile sul Visual Studio Marketplace il 18 maggio 2026. Un lasso di tempo apparentemente irrisorio, ma sufficiente perché il gruppo criminale TeamPCP compromettesse il device di almeno un dipendente GitHub e sottraesse circa 3.800 repository interni — uno degli incidenti di supply chain più gravi dell’anno sul piano dell’impatto sistemico.

Il contesto: TeamPCP e la catena TanStack


Per capire la violazione di GitHub è necessario risalire di dieci giorni. L’11 maggio 2026, TeamPCP aveva già pubblicato 84 artifact npm malevoli distribuiti su 42 pacchetti nel namespace TanStack — uno degli ecosistemi più adottati per il web development con React. Quell’operazione, che il sito ha seguito nelle settimane precedenti nella campagna Mini Shai-Hulud, aveva come obiettivo la compromissione a cascata di developer tramite dipendenze malevole che esfiltravano credenziali e token durante l’installazione.

TeamPCP ha guadagnato notorietà rapidamente come attore specializzato negli attacchi alla developer trust surface: non attacca i sistemi delle vittime direttamente, ma compromette la catena di strumenti e dipendenze su cui i developer si fidano implicitamente ogni giorno. L’attacco TanStack era già sufficientemente grave da soli — ma era anche il setup per qualcosa di più ambizioso.

Il vettore: Nx Console 18.95.0


Nx Console (nrwl.angular-console) è un’estensione VS Code con 2,2 milioni di installazioni e lo status di verified publisher — la certificazione più alta che Microsoft assegna agli editori sul marketplace. Questa combinazione di popolarità e fiducia istituzionale ne fa un bersaglio di enorme valore per un attore supply chain.

Il team di Nx ha successivamente ricostruito la catena causale: uno dei propri developer era stato precedentemente compromesso nel contesto dell’attacco a TanStack. Le sue credenziali GitHub erano trapelate, permettendo a TeamPCP di accedere al repository dell’estensione, modificare il codice, e pubblicare la versione 18.95.0 — quella avvelenata. Il meccanismo era semplice ma letale: non appena un developer apriva qualsiasi workspace in VS Code con l’estensione installata, il malware iniziava a raccogliere silenziosamente le credenziali memorizzate nel sistema.

La timeline dell’attacco


  • 11 maggio 2026 — TeamPCP pubblica 84 pacchetti npm malevoli nel namespace TanStack; un developer Nx viene compromesso
  • 18 maggio 2026, 12:30 UTC — Nx Console 18.95.0 (versione backdoor) appare sul VS Code Marketplace
  • 18 maggio 2026, 12:48 UTC — La versione malevola viene rimossa dal Marketplace (18 minuti di esposizione)
  • 18 maggio 2026, ~13:06 UTC — Rimossa da Open VSX (36 minuti totali di esposizione)
  • 20 maggio 2026 — GitHub conferma la violazione: circa 3.800 repository interni esfiltrati, avvio rotazione di tutti i secret esposti


L’impatto: 3.800 repository interni di GitHub


GitHub ha confermato la sottrazione di circa 3.800 repository interni a opera di TeamPCP. L’azienda ha proceduto immediatamente alla rotazione di tutti i secret potenzialmente esposti. Non è ancora stato reso noto se i repository contengano codice relativo alla piattaforma github.com stessa, strumenti interni, infrastrutture di supporto o documentazione riservata — ma la sola portata numerica dell’esfiltrazione suggerisce un accesso profondo all’ecosistema di sviluppo interno di Microsoft GitHub. L’incidente ha colpito anche Grafana, compromessa attraverso un percorso diverso ma sempre legato alla catena TanStack.

Perché questo attacco è strutturalmente diverso


A differenza dei classici attacchi alla supply chain che operano a livello di package manager (npm, PyPI), questo incidente colpisce il layer dell’IDE — la superficie più prossima al developer e quella con i privilegi di accesso più ampi. Un’estensione VS Code non è un pacchetto passivo: ha accesso al filesystem locale, alle variabili d’ambiente di sistema, ai token Git memorizzati, alle chiavi SSH, ai file di configurazione cloud e all’intera sessione di sviluppo attiva.

Un’estensione verified con milioni di installazioni diventa, una volta compromessa, un vettore di distribuzione quasi impossibile da bloccare con le tradizionali difese perimetrali. La maggior parte degli endpoint detection agent non monitora il comportamento delle estensioni IDE con la stessa granularità con cui monitora i processi di sistema — un gap che TeamPCP ha sfruttato con precisione chirurgica.

Due righe per i difensori


L’incidente impone una revisione urgente della postura di sicurezza degli ambienti di sviluppo. I team di sicurezza dovrebbero verificare immediatamente se l’estensione Nx Console 18.95.0 è stata installata su device aziendali nel periodo 11–20 maggio 2026, e in caso affermativo avviare la rotazione di tutte le credenziali presenti sui sistemi coinvolti — token GitHub, chiavi SSH, credenziali cloud, certificati. È fondamentale estendere il monitoraggio EDR alle estensioni IDE, configurando alert per comportamenti anomali come lettura massiva di file di configurazione, accesso ai credential store di sistema o connessioni di rete originate dal processo VS Code verso endpoint inusuali. Sul piano organizzativo, è necessario implementare il principio del minimo privilegio per le credenziali usate negli ambienti di sviluppo: i developer non dovrebbero mai usare token con permessi di scrittura su repository interni critici sui propri device personali. Infine, considerare l’adozione di ambienti di sviluppo isolati — container o VM dedicati — per i progetti a più alto rischio, separando fisicamente l’ambiente di esecuzione del codice dall’ambiente di lavoro quotidiano.

Tech in Plain Sight: The Mechanics of String Trimmers


The media in this post is not displayed to visitors. To view it, please log in.

My old friend Jeff was always vocally upset that he didn’t come up with the idea of a string trimmer, commonly known as a Weed Eater or Weed Whacker. On the one hand, the idea is totally simple: spin some nylon line and cut grass and other relatively soft things. But, it turns out, that making the device actually usable requires a little bit of mechanical engineering.

Of course, the noisy part is a motor. The motor — driven by an engine, a battery, or a power cord — spins a flexible nylon line fast enough that the line becomes rigid from centrifugal force. That’s not the important part.

The humble spool at the bottom of the trimmer is where decades of mechanical engineering, questionable patents, consumer frustration, and genuine cleverness all meet. The earliest string trimmers were primitive. [George Ballas], who patented the Weed Eater in the early 1970s, reportedly got the idea from the rotating brushes in a car wash. Attach flexible cords to a spinning head, and they become cutting tools. In fact, the prototype used a tin can for the head. Elegant. But once the line wears down — which it does constantly — you need a way to expose fresh line. That turns out to be harder than it sounds.

The Simplest System


The easiest approach is fixed-length line. Some trimmers still work this way. You cut short pieces of heavy line (or buy it precut) and insert them into holes in the head. No spool. No springs. No moving parts.

These systems are rugged and are popular on commercial units designed to survive abuse. They also work well with thicker lines or even plastic blades. But they are annoying because every time the line wears out, you stop working and manually replace it. Spool-based systems became dominant very quickly.

The basic spool idea is straightforward enough. Wind a long nylon filament onto a reel. Some reels have two sections to feed line out on two sides of the rotating head. As the line wears away, feed out more line from the spool. But how do you do that while the thing is spinning at several thousand RPM?

Bump Feed


If you’ve ever lightly smacked the bottom of a running trimmer against the ground, you’ve used a bump feed mechanism.

Inside the head is a spool loaded with line and pressed upward by a spring. The line exits through eyelets on the side of the head. Under normal operation, friction and centrifugal force keep the spool from turning freely.

When you bump the bottom of the head against the ground, inertia momentarily compresses the spring and disengages locking tabs or detents. The spool can rotate briefly, paying out a short amount of line. When you release pressure, the spring re-engages the lock.

At least, that’s the theory. In practice, bump heads have to balance several competing requirements. The spool must not unwind accidentally. The line can’t bind. Dirt and grass clippings can’t jam the mechanism. The head must survive repeated impacts with concrete, rocks, and fence posts because users inevitably abuse them.

And then there’s the line itself. Nylon trimmer line is more complicated than it looks. Different diameters, shapes, and stiffnesses affect how well the feed works. Star-shaped line cuts aggressively but tangles more easily. Round line feeds smoothly but cuts less efficiently. Humidity even matters because nylon absorbs water. Anyone who has left old trimmer line in a garage for years has probably discovered brittle line snapping constantly. We’ve heard people suggest you soak the line — especially old line — in water overnight before loading it.

youtube.com/embed/MB0hM3-0RQE?…

The bump feed mechanism has another subtle trick. Many heads rely on centrifugal force not only to stiffen the line but also to help lock the spool during operation. At speed, the line pulls outward hard enough to increase friction on the spool. When rotation slows, the spool loosens slightly. A simple mechanical solution.

Of course, they don’t always work and when that happens, you might find some troubleshooting advice in the video from [Will Shackleton] below.

youtube.com/embed/K5B-0YZ-FEQ?…

Automatic Feed


Of course, someone decided bump feed was too much work and, thus, the automatic feed was born. These heads attempt to sense when the line has become too short and feed more automatically. These systems are common on electric consumer trimmers.

There are several ways to do this, but many use a ratchet-like mechanism tied to motor speed. When the load on the motor changes because the line becomes shorter, the system advances the spool slightly. Some units feed line every time the motor starts. Others use centrifugal clutches or vibration-sensitive mechanisms. Great when it works.

Part of the problem is that the operating environment is terrible. Grass juice, dirt, vibration, heat, and impacts are all happening simultaneously. It is hard enough to make reliable machinery in a clean factory. Designing a precise mechanism that lives inches from flying mud is another matter entirely. That’s why many professionals prefer simple bump heads despite the inconvenience. Simpler systems usually fail less dramatically.

You can see several head styles in the video below.

youtube.com/embed/nIr2t-bIj4k?…

The Eyelets Matter More Than You Think


One overlooked component is the eyelet where the line exits the head. That little metal or ceramic ring takes an enormous amount of abuse. The line is moving at perhaps 200 miles per hour at the tip, vibrating continuously, and carrying abrasive dirt particles. A plain plastic hole would wear out quickly.

Some trimmers use hardened steel inserts. Others use aluminum oxide ceramics. The better heads often have replaceable eyelets because manufacturers know they are consumable parts.

The angle matters, too. The line should exit smoothly with minimal friction but still maintain enough control to prevent tangling. You probably don’t notice how important the eyelet is, but you’d notice if it were poorly designed.

Why Tangling Happens


Anyone who has reloaded a spool badly knows the pain of internal tangles. The spool effectively stores torsional energy. If the line is wound unevenly or crosses over itself, it can dig into lower layers under centrifugal load. Once that happens, the line jams. Pulling harder only makes it worse.

This is why most spools have directional arrows molded into them. The line must wind in the correct direction, so rotational forces tighten the winding instead of loosening it.

Modern “easy load” heads try to solve this by allowing users to thread the line straight through the head and then twist a knob to wind it automatically. These systems are genuinely better than older designs, although many still become incomprehensible the first time you disassemble one accidentally.

One trick we’ve heard is that if you spray a lubricant like WD-40 into the eyelet before you use the trimmer, it will help the mechanism feed more smoothly. Let us know if you’ve ever tried that and how it works.

Batteries Changed the Game


Cordless electric trimmers have altered feed mechanism design in subtle ways. Gas trimmers typically run at nearly constant speed, which makes centrifugal systems predictable. Battery trimmers vary speed more often due to electronic controls and power-saving logic. That means newer designs increasingly depend on passive mechanical systems rather than RPM-sensitive tricks. Electronic control also allows some high-end trimmers to detect load changes more intelligently.

Ironically, while motors and batteries have become dramatically more sophisticated, the line feed mechanism is still mostly springs, friction surfaces, tabs, and molded plastic. No microcontroller. No electronic sensors. Go figure.

The string trimmer looks like a brute-force tool. But hidden inside that disposable-looking plastic head is a surprisingly nuanced mechanical system balancing centrifugal force, friction, vibration, inertia, wear, and user abuse. Poor [George Ballas]. He took his prototype to toolmakers, who were all uninterested in the invention. He started the Weed Eater company and launched a lucrative product category.

We love finding all the strange tech around us, from shopping carts to gas pumps.

Un lasso di tempo apparentemente irrisorio, ma sufficiente perché il gruppo criminale TeamPCP compromettesse il device di almeno un dipendente GitHub e sottraesse circa 3.800 repository interni — uno degli incidenti di supply chain più gravi dell’anno sul piano dell’impatto sistemico.

Il contesto: TeamPCP e la catena TanStack


Per capire la violazione di GitHub è necessario risalire di dieci giorni. L’11 maggio 2026, TeamPCP aveva già pubblicato 84 artifact npm malevoli distribuiti su 42 pacchetti nel namespace TanStack — uno degli ecosistemi più adottati per il web development con React. Quell’operazione, che il sito ha seguito nelle settimane precedenti nella campagna Mini Shai-Hulud, aveva come obiettivo la compromissione a cascata di developer tramite dipendenze malevole che esfiltravano credenziali e token durante l’installazione.

TeamPCP ha guadagnato notorietà rapidamente come attore specializzato negli attacchi alla developer trust surface: non attacca i sistemi delle vittime direttamente, ma compromette la catena di strumenti e dipendenze su cui i developer si fidano implicitamente ogni giorno. L’attacco TanStack era già sufficientemente grave da soli — ma era anche il setup per qualcosa di più ambizioso.

Il vettore: Nx Console 18.95.0


Nx Console (nrwl.angular-console) è un’estensione VS Code con 2,2 milioni di installazioni e lo status di verified publisher — la certificazione più alta che Microsoft assegna agli editori sul marketplace. Questa combinazione di popolarità e fiducia istituzionale ne fa un bersaglio di enorme valore per un attore supply chain.

Il team di Nx ha successivamente ricostruito la catena causale: uno dei propri developer era stato precedentemente compromesso nel contesto dell’attacco a TanStack. Le sue credenziali GitHub erano trapelate, permettendo a TeamPCP di accedere al repository dell’estensione, modificare il codice, e pubblicare la versione 18.95.0 — quella avvelenata. Il meccanismo era semplice ma letale: non appena un developer apriva qualsiasi workspace in VS Code con l’estensione installata, il malware iniziava a raccogliere silenziosamente le credenziali memorizzate nel sistema.

La timeline dell’attacco


  • 11 maggio 2026 — TeamPCP pubblica 84 pacchetti npm malevoli nel namespace TanStack; un developer Nx viene compromesso
  • 18 maggio 2026, 12:30 UTC — Nx Console 18.95.0 (versione backdoor) appare sul VS Code Marketplace
  • 18 maggio 2026, 12:48 UTC — La versione malevola viene rimossa dal Marketplace (18 minuti di esposizione)
  • 18 maggio 2026, ~13:06 UTC — Rimossa da Open VSX (36 minuti totali di esposizione)
  • 20 maggio 2026 — GitHub conferma la violazione: circa 3.800 repository interni esfiltrati, avvio rotazione di tutti i secret esposti


L’impatto: 3.800 repository interni di GitHub


GitHub ha confermato la sottrazione di circa 3.800 repository interni a opera di TeamPCP. L’azienda ha proceduto immediatamente alla rotazione di tutti i secret potenzialmente esposti. Non è ancora stato reso noto se i repository contengano codice relativo alla piattaforma github.com stessa, strumenti interni, infrastrutture di supporto o documentazione riservata — ma la sola portata numerica dell’esfiltrazione suggerisce un accesso profondo all’ecosistema di sviluppo interno di Microsoft GitHub. L’incidente ha colpito anche Grafana, compromessa attraverso un percorso diverso ma sempre legato alla catena TanStack.

Perché questo attacco è strutturalmente diverso


A differenza dei classici attacchi alla supply chain che operano a livello di package manager (npm, PyPI), questo incidente colpisce il layer dell’IDE — la superficie più prossima al developer e quella con i privilegi di accesso più ampi. Un’estensione VS Code non è un pacchetto passivo: ha accesso al filesystem locale, alle variabili d’ambiente di sistema, ai token Git memorizzati, alle chiavi SSH, ai file di configurazione cloud e all’intera sessione di sviluppo attiva.

Un’estensione verified con milioni di installazioni diventa, una volta compromessa, un vettore di distribuzione quasi impossibile da bloccare con le tradizionali difese perimetrali. La maggior parte degli endpoint detection agent non monitora il comportamento delle estensioni IDE con la stessa granularità con cui monitora i processi di sistema — un gap che TeamPCP ha sfruttato con precisione chirurgica.

Due righe per i difensori


L’incidente impone una revisione urgente della postura di sicurezza degli ambienti di sviluppo. I team di sicurezza dovrebbero verificare immediatamente se l’estensione Nx Console 18.95.0 è stata installata su device aziendali nel periodo 11–20 maggio 2026, e in caso affermativo avviare la rotazione di tutte le credenziali presenti sui sistemi coinvolti — token GitHub, chiavi SSH, credenziali cloud, certificati. È fondamentale estendere il monitoraggio EDR alle estensioni IDE, configurando alert per comportamenti anomali come lettura massiva di file di configurazione, accesso ai credential store di sistema o connessioni di rete originate dal processo VS Code verso endpoint inusuali. Sul piano organizzativo, è necessario implementare il principio del minimo privilegio per le credenziali usate negli ambienti di sviluppo: i developer non dovrebbero mai usare token con permessi di scrittura su repository interni critici sui propri device personali. Infine, considerare l’adozione di ambienti di sviluppo isolati — container o VM dedicati — per i progetti a più alto rischio, separando fisicamente l’ambiente di esecuzione del codice dall’ambiente di lavoro quotidiano.

Transforming Lamp Built With LED Filaments


The media in this post is not displayed to visitors. To view it, please log in.

[Nick Electronics] had an idea to build a stylish lamp that could transform its shape while lit. This goal was achieved beautifully with the aid of many, many filament LEDs.

If you’re unfamiliar with filament LEDs, they’re basically thin plastic filaments stuffed with lots of individual LEDs that are very close together. This effectively creates a continuous, flexible, glowing string that can be used for all sorts of creative purposes.

[Nick] packed the lights into an interlocking stack of PCBs that make up the lamp’s structure. Each PCB layer hosts four filaments mounted around the outer edge, and has a pin that locks into a groove in the next layer to allow them to tug each other around as they turn. The PCBs rotate around a central shaft, with power passed from one to the other via interlinking wires. Drive is via a stepper motor on top of the lamp, controlled by an A4988 driver. There’s also an ATmega48 microcontroller onboard, which is the brains of the operation. A DC-DC converter onboard steps up the 5 V input voltage from USB-C to 10 volts for the stepper motor.

It’s neat to watch the lamp in action, glowing and slowly shifting in patterns as the layers catch and rotate in and out of alignment. We’ve seen interesting builds in this vein before, like this fantastic origami lamp from a few years ago.

@treleonora @informapirata Ciao Eleonora, ti ringrazio, davvero gentile!
Ho dato uno sguardo velocissimo alla guida che mi hai girato. Devo ammettere che non la merito, per due semplici motivi:
1) non capisco quasi nulla del mondo dell'informatica. La maggior parte dei termini relativi a software ed hardware mi sono totalmente sconosciuti.
2) non riesco a trovare il modo di superare questo mio limite ed accetto passivamente di essere tagliato fuori da questo mondo.
Ma ribadisco, gentilissima!

AHAHAHA 😂 mi sembra un'ammissione onesta, soprattutto considerando che ho cercato di essere il più semplice essere rumeno tecnico possibile.
Ti chiederei però se potessi farmi delle osservazioni più dettagliate, perché mi aiuterebbero a tarare meglio l'obiettivo di creare una guida pratica che sto elaborando e che non dia per scontato nulla e che non parli di nulla che non sia strettamente necessario all'utilizzo.
Ti va?

@informapirata @treleonora Ciao! Ho capito finché hai fatto l'esempio scuola dell'obbligo e università. Sei stato chiarissimo! 😁
È un problema psicologico il mio. Posso leggere filosofia e fisica teorica, se non conosco un termine vado ad approfondire, non mi costa farlo.
Invece se leggo un termine relativo a questo mondo, mi si chiude lo stomaco.

@informapirata @treleonora La tua guida è ottima, me ne rendo conto vedendo quanto è dettagliata (anche con immagini a prova di analfabeta).
Davvero, il problema non sono le spiegazioni, ma io che mi rifiuto di apprendere.

Scatto foto. Non me ne faccio nulla dei likes.
Preferirei un commento, anche negativo se costruttivo. Sono fatto così.

Grazie dell' attenzione @informapirata 🩵

Hai toccato un punto fondamentale. Infatti Fuori da ogni moralismo (perché noi fedi-amatori pensiamo che tutti dovrebbero "imparare il fediverso" 🤣) è essenziale che le persone utilizzino questi software senza essere costretti a sapere esattamente quello che fanno.

> Scatto foto

Giusto. E tu da bravo fotografo mi hai rappresentato la scena da un punto di vista non banale. Penso che ci risentiremo😅

Mandato di arresto dalla CPI per Smotrich: “Sarà guerra”. E ordina la demolizione di un villaggio palestinese

La Corte penale internazionale ha chiesto un mandato di arresto per Benjamin Netanyahu, primo ministro di Israele, Bezalel Smotrich, Ministro delle Finanze e per Itamar Ben Gvir, Ministro della sicurezza. Una notizia che era stata anticipata dal quotidiano israeliano Haaretz e che viene commentata dallo stesso Smotrich in una conferenza stampa nella quale il leader del partito Sionismo Religioso ha immediatamente rilanciato. "È una corte antisemita", ha detto riferendosi ai giudici de L'Aja.

Magnets Are Bad For Hardware Again


The media in this post is not displayed to visitors. To view it, please log in.

If you were around tech in the bad old days, magnets could be really bad news. They were fine on the fridge, no problem at all. Put one near a floppy disk, or a hard drive, or even a computer monitor, though, and you were in for some pain. You’d lose data, possibly permanently destroy a disk or drive, or you’d get ugly smeary rainbow effects all over your screen.

The solid state revolution has eliminated a lot of these problems. We all use SSDs, flash drives, and LCD monitors now, all of which care a lot less about flirting with magnets. However, the same can’t be said about all our modern hardware, for a magnet could cause your smartphone some major grief indeed.

Magnetic Fields

As you might expect, the magnetic susceptibility of certain modern smartphones once again comes down to non-solid state parts. Now, there aren’t exactly a lot of phones out there that are packing hard drives or floppy drives or any sort of magnetic storage. Instead, it all comes down to cameras.

Take the modern iPhone line, for example. Apple is quite careful to warn against carelessly using magnetic accessories with the smartphone, because it can interfere with the cameras. Specifically, it’s because of the optical image stabilization (OIS) and closed-loop autofocus systems that are built into the cameras themselves. These devices use magnetic position sensors to determine lens position to compensate for focus, vibration, and movement, and use magnetic voice coil actuators to move optical elements, in order to take the best possible photos and videos at all times. If there’s a strong magnetic field in the vicinity of the lenses, it can interfere with this operation.
It’s common for modern smartphones to have tiny actuators built into the camera assemblies to handle autofocus and optical image stabilization. Credit: Samsung
Few of us are sticking fridge magnets on our iPhones, to be sure. However, there are a lot of magnetic cases and mounts and other accessories that give people a great reason to stick magnets on their phone. In the cases of some third-party accessories that are poorly designed, it’s possible for these to cause problems with the camera if the magnets are too strong or too close to the key hardware. It’s worth noting that in typical use, something like a magnetic case or other small magnet won’t cause a lot of permanent harm. It will generally just degrade the operation of the camera until the magnet is removed.

This isn’t solely an iPhone problem, either. It can affect any phone that has any sort of magnetic sensing or actuation involved in the camera mechanism. Indeed, Samsung has even filed a patent on ways to mitigate this problem through carefully orientating the magnets used in folding phone mechanisms, and the appropriate use of shielding. Ultimately, similar camera technology is used in a great many phones, all of which are susceptible to this problem.

It’s true that in day to day use, you’re probably not going to run into a lot of problems waving around a magnet near your smartphone. Nor did floppy disks fail en masse in the 90’s, unless one of your colleagues was feeling vindictive and wiped them all with a fridge magnet on their lunch break. Still, like the oddball helium problem that because apparent with smartphones a few years ago, it’s funny to think that magnets could be causing trouble with computer hardware today. The fact is that a modern smartphone contains multitudes, and thus can surprise you with its edge case frailties.
