Telegram perde il suo status di piattaforma comoda per i criminali informatici
Telegram, che nel corso della sua storia è diventata una delle app di messaggistica più popolari al mondo, sta gradualmente perdendo il suo status di piattaforma comoda per i criminali informatici.
Gli analisti di Kaspersky Lab hanno monitorato il ciclo di vita di centinaia di canali underground e hanno concluso che la moderazione più severa stanno letteralmente estromettendo l’underground dall’app di messaggistica.
Gli esperti sottolineano che Telegram è inferiore alle app di messaggistica sicura dedicate in termini di protezione della privacy: le chat non utilizzano la crittografia end-to-end di default, l’intera infrastruttura è centralizzata e il codice del server è chiuso.
Sebbene questo probabilmente non rappresenti un problema significativo per l’utente medio, implica la dipendenza da terze parti e il rischio di deanonimizzazione per i criminali. Non è un caso che le proposte di vietare completamente Telegram per motivi di lavoro siano sempre più frequenti sui forum underground.

Tuttavia, sono proprio le funzionalità integrate del servizio a renderlo una piattaforma aziendale conveniente per i criminali.
I bot gestiscono l’accettazione e il pagamento degli ordini, vendono log di infostealer , abbonamenti MaaS, servizi di doxxing, frodi con carte di credito e altre frodi online minori. Questa attività criminale “snella” e altamente automatizzata si adatta perfettamente al modello di Telegram: il proprietario è in gran parte estraneo alle operazioni e i file pubblicati sui canali vengono archiviati a tempo indeterminato.
Tuttavia, prodotti esclusivi – accesso alle reti aziendali, exploit zero-day– rimangono sui forum darknet tradizionali con sistemi di reputazione, depositi e garanzie sulle transazioni.
Una sezione separata dello studio è dedicata alla durata di vita dei canali underground. Sulla base dei dati di oltre 800 risorse bloccate, gli analisti hanno stimato la loro durata media in circa sette mesi. Tuttavia, la mediana è aumentata: mentre nel 2021-2022 un canale durava in media cinque mesi, nel 2023-2024 ha raggiunto i nove. Ciò non significa che la persecuzione sia diminuita: il grafico dei blocchi mostra un forte picco nel 2022, legato all’attività degli hacktivisti, e livelli costantemente elevati fino a metà del 2025. Anche i minimi di fine 2024 sono paragonabili ai picchi del 2023.
I criminali informatici stanno cercando di adattarsi: cambiano canale in modalità “on-demand”, pubblicano messaggi “innocui” per camuffare la propria identità e annotano i post con disclaimer e dichiarazioni sulla legalità del contenuto. Tuttavia, un’analisi di risorse di lunga data mostra che queste misure vengono applicate sporadicamente e generalmente non riescono a impedire il blocco.
Di conseguenza, grandi comunità stanno iniziando a cercare alternative. Ad esempio, nel 2025, uno dei gruppi più grandi, BFRepo, con quasi 9.000 iscritti, ha annunciato il suo passaggio al messenger decentralizzato SimpleX dopo una serie di ban su Telegram. Un altro gruppo ben noto, Angel Drainer, si è spinto ancora oltre e ha lanciato il proprio messenger chiuso con il presunto supporto per i moderni protocolli crittografici, raccomandando allo stesso tempo agli utenti di abbandonare Telegram.
Gli autori del rapporto concludono in modo inequivocabile: Telegram un tempo sembrava un rifugio relativamente sicuro per i criminali, ma quell’era sta finendo. La crescente moderazione e la pressione da parte di vari attori, dai detentori di copyright ai gruppi di hacktivisti, stanno rendendo l’infrastruttura underground del messenger sempre più instabile.
Tuttavia, la scomparsa dei canali underground da Telegram non significa una riduzione delle minacce informatiche: le comunità criminali stanno semplicemente migrando verso altri servizi o sviluppando soluzioni proprie. Gli analisti esortano le aziende e gli specialisti della sicurezza informatica a monitorare attentamente la migrazione delle piattaforme e ad adattare i propri sistemi di monitoraggio ai nuovi focolai di attività criminale informatica.

Step into my Particle Accelerator
If you get a chance to visit a computer history museum and see some of the very old computers, you’ll think they took up a full room. But if you ask, you’ll often find that the power supply was in another room and the cooling system was in yet another. So when you get a computer that fit on, say, a large desk and maybe have a few tape drives all together in a normal-sized office, people thought of it as “small.” We’re seeing a similar evolution in particle accelerators, which, a new startup company says, can be room-sized according to a post by [Charles Q. Choi] over at IEEE Spectrum.
Usually, when you think of a particle accelerator, you think of a giant housing like the 3.2-kilometer-long SLAC accelerator. That’s because these machines use magnets to accelerate the particles, and just like a car needs a certain distance to get to a particular speed, you have to have room for the particle to accelerate to the desired velocity.
A relatively new technique, though, doesn’t use magnets. Instead, very powerful (but very short) laser pulses create plasma from gas. The plasma oscillates in the wake of the laser, accelerating electrons to relativistic speeds. These so-called wakefield accelerators can, in theory, produce very high-energy electrons and don’t need much space to do it.
The startup company, TAU Systems, is about to roll out a commercial system that can generate 60 to 100 MeV at 100 Hz. They also intend to increase the output over time. For reference, SLAC generates 50,000 MeV. But, then again, it takes two miles of raceway to do it.
The initial market is likely to be radiation testing for space electronics. Higher energies will open the door to next-generation X-ray lithography for IC production, and more. There are likely applications for accelerated electrons that we don’t see today because it isn’t feasible to generate them without a massive facility.
On the other hand, don’t get your checkbook out yet. The units will cost about $10 million at the bottom end. Still a bargain compared to the alternatives.
You can do some of this now on a chip. Particle accelerators have come a long way.

Designing a Simpler Cycloidal Drive
Cycloidal drives have an entrancing motion, as well as a few other advantages – high torque and efficiency, low backlash, and compactness among them. However, much as [Sergei Mishin] likes them, it can be difficult to 3D-print high-torque drives, and it’s sometimes inconvenient to have the input and output shafts in-line. When, therefore, he came across a video of an industrial three-ring reducing drive, which works on a similar principle, he naturally designed his own 3D-printable drive.
The main issue with 3D-printing a normal cycloidal drive is with the eccentrically-mounted cycloidal plate, since the pins which run through its holes need bearings to keep them from quickly wearing out the plastic plate at high torque. This puts some unfortunate constraints on the size of the drive. A three-ring drive also uses an eccentric drive shaft to cause cycloidal plates to oscillate around a set of pins, but the input and output shafts are offset so that the plates encompass both the pins and the eccentric driveshaft. This simplifies construction significantly, and also makes it possible to add more than one input or output shaft.
As the name indicates, these drives use three plates 120 degrees out of phase with each other; [Sergei] tried a design with only two plates 180 degrees out of phase, but since there was a point at which the plates could rotate just as easily in either direction, it jammed easily. Unlike standard cycloidal gears, these plates use epicycloidal rather than hypocycloidal profiles, since they move around the outside of the pins. [Sergei] helpfully wrote a Python script that can generate profiles, animate them, and export to DXF. The final performance of these drives will depend on their design parameters and printing material, but [Sergei] tested a 20:1 drive and reached a respectable 9.8 Newton-meters before it started skipping.
Even without this design’s advantages, it’s still possible to 3D-print a cycloidal drive, its cousin the harmonic drive, or even more exotic drive configurations.

Amiibo Emulator Becomes Pocket 2.4 GHz Spectrum Analyzer
As technology marches on, gear that once required expensive lab equipment is now showing up in devices you can buy for less than a nice dinner. A case in point: those tiny displays originally sold as Nintendo amiibo emulators. Thanks to [ATC1441], one of these pocket-sized gadgets has been transformed into 2.4 GHz spectrum analyzer.
These emulators are built around the Nordic nRF52832 SoC, the same chip found in tons of low-power Bluetooth devices, and most versions come with either a small LCD or OLED screen plus a coin cell or rechargeable LiPo. Because they all share the same core silicon, [ATC1441]’s hack works across a wide range of models. Don’t expect lab-grade performance; the analyzer only covers the range the Bluetooth chip inside supports. But that’s exactly where Wi-Fi, Bluetooth, Zigbee, and a dozen other protocols fight for bandwidth, so it’s perfect for spotting crowded channels and picking the least congested one.
Flashing the custom firmware is dead simple: put the device into DFU mode, drag over the .zip file, and you’re done. All the files, instructions, and source are up on [ATC1441]’s PixlAnlyzer GitHub repo. Check out some of the other amiibo hacks we’ve featured as well.

Extremely Rare Electric Piano Restoration
Not only are pianos beautiful musical instruments that have stood the test of many centuries of time, they’re also incredible machines. Unfortunately, all machines wear out over time, which means it’s often not feasible to restore every old piano we might come across. But a few are worth the trouble, and [Emma] had just such a unique machine roll into her shop recently.
What makes this instrument so unique is that it’s among the first electric pianos to be created, and one of only three known of this particular model that survive to the present day. This is a Vivi-Tone Clavier piano which dates to the early 1930s. In an earlier video she discusses more details of its inner workings, but essentially it uses electromagnetic pickups like a guitar to detect vibrations in plucked metal reeds.
To begin the restoration, [Emma] removes the action and then lifts out all of the keys from the key bed. This instrument is almost a century old so it was quite dirty and needed to be cleaned. The key pins are lubricated, then the keys are adjusted so that they all return after being pressed. From there the keys are all adjusted so that they are square and even with each other. With the keys mostly in order, her attention turns to the action where all of the plucking mechanisms can be filed, and other adjustments made. The last step was perhaps the most tedious, which is “tuning” the piano by adjusting the pluckers so that all of the keys produce a similar amount or volume of sound, and then adding some solder to the reeds that were slightly out of tune.
With all of those steps completed, the piano is back in working order, although [Emma] notes that since these machines were so rare and produced so long ago there’s no real way to know if the restoration sounds like what it would have when it was new. This is actually a similar problem we’ve seen before on this build that hoped to model the sound of another electric instrument from this era called the Luminaphone.

Journalists warn of silenced sources
From national outlets to college newspapers, reporters are running into the same troubling trend: sources who are afraid to speak to journalists because they worry about retaliation from the federal government.
This fear, and how journalists can respond to it, was the focus of a recent panel discussion hosted by Freedom of the Press Foundation (FPF), the Association of Health Care Journalists, and the Society of Environmental Journalists. Reporters from a range of beats described how the second Trump administration has changed the way people talk to the press, and what journalists do to reassure sources and keep them safe.
youtube.com/embed/rIyRDQFEl4k?…
For journalist Grace Hussain, a solutions correspondent at Sentient Media, this shift became unmistakable when sources who relied on federal funding suddenly backed out of participating in her reporting. “Their concerns were very legitimate,” Hussain said, “It was possible that their funding could get retracted or withdrawn” for speaking to the press.
When Hussain reached out to other reporters, she found that sources’ reluctance to speak to the press for fear of federal retaliation is an increasingly widespread issue that’s already harming news coverage. “There are a lot of stories that are under-covered, and it’s just getting more difficult at this point to do that sort of coverage with the climate that we’re in,” she said.
Lizzy Lawrence, who covers the Food and Drug Administration for Stat, has seen a different but equally unsettling pattern. Lawrence has found that more government sources want to talk about what’s happening in their agencies, but often only if they’re not named. Since Trump returned to office, she said, many sources “would request only to speak on the condition of anonymity, because of fears of being fired.” As a result, her newsroom is relying more on confidential sources, with strict guardrails, like requiring multiple sources to corroborate information.
For ProPublica reporter Sharon Lerner, who’s covered health and the environment across multiple administrations, the heightened fear is impossible to miss. Some longtime sources have cut off communication with her, including one who told her they were falsely suspected of leaking.
And yet, she added, speaking to the press may be one of the last options left for employees trying to expose wrongdoing. “So many of the avenues for federal employees to seek justice or address retaliation have been shut down,” Lerner said.
This chilling effect extends beyond federal agencies. Emily Spatz, editor-in-chief of Northeastern’s independent student newspaper The Huntington News, described how fear spread among international students after federal agents detained Mahmoud Kahlil and Rümeysa Öztürk. Visa revocations of students at Northeastern only deepened the concern.
Students started asking the newspaper to take down previously published op-eds they worried could put them at risk, a step Spatz took after careful consideration. The newsroom ultimately removed six op-eds but posted a public website documenting each removal to preserve transparency.
Even as the paper worked hard to protect sources, many became reluctant to participate in their reporting. One student, for instance, insisted the newspaper remove a photo showing the back of their head, a method the paper had used specifically to avoid identifying sources.
Harlo Holmes, the chief information security officer and director of digital security at FPF, said these patterns mirror what journalists usually experience under authoritarian regimes, but — until now — have not been seen in the United States. Whistleblowing is a “humongously heroic act,” Holmes said, “and it is not always without its repercussions.”
She urged reporters to adopt rigorous threat-modeling practices and to be transparent with sources about the tools and techniques they use to keep them safe. Whether using SecureDrop, Signal, or other encrypted channels, she said journalists should make it easy for sources to find out how to contact them securely. “A little bit of education goes a long way,” she said.

Covering immigration in a climate of fear
As the federal government ramps up immigration enforcement, sweeping through cities, detaining citizens and noncitizens, separating families, and carrying out deportations, journalists covering immigration have had to step up their work, too.
Journalists on the immigration beat today are tasked with everything from uncovering government falsehoods to figuring out what their communities need to know and protecting their sources. Recently, Freedom of the Press Foundation (FPF) hosted a conversation with journalists Maritza Félix, the founder and director of Conecta Arizona; Arelis Hernández, a reporter for The Washington Post; and Lam Thuy Vo, an investigative reporter with Documented. They discussed the challenges they face and shared how they report on immigration with humanity and accuracy, while keeping their sources and themselves safe.
youtube.com/embed/OPPo0YzKfnA?…
Immigration reporting has grown a lot more difficult, explained Hernández, as sources increasingly fear retaliation from the government. “I spend a lot of time at the front end explaining, ‘Where will this go? What will it look like?’” Hernández said, describing her process of working with sources to ensure they participate in reporting knowingly and safely. She also outlined her own precautions, from using encrypted devices to carrying protective gear, highlighting just how unsafe conditions have become, even for U.S.-born reporters.
Like Hernández, Félix also emphasized the intense fear and uncertainty many immigrant sources experience. Other sources, however, may be unaware of the possible consequences of speaking to reporters and need to be protected as well. “I think when we’re talking about sources, particularly with immigration, we’re talking about people who are sharing their most vulnerable moments in their life, and I think the way that we treat it is going to be very decisive on their future,” she said.
Journalists who are themselves immigrants must also manage personal risk, Félix said, “but the risk is always going to be there just because of who we are and what we represent in this country.” She pointed to the arrest and deportation of journalist Mario Guevara in Georgia, saying it “made me think that could have been me” before she became a U.S. citizen. She recommended that newsrooms provide security training, mental health resources, and operational protocols for both staff and freelancers.
Both Félix and Vo, who work in newsrooms by and for immigrant communities, emphasized the need for journalists to actively listen to the people they cover. “If you’re trying to serve immigrants, build a listening mechanism, some kind of way of continuing to listen to both leaders in the community, service providers, but also community members,” Vo advised. She also recommended that journalists use risk assessments and threat modeling to plan how to protect themselves and their sources.
