Bug da Oscar (score 10) per Cisco Secure Firewall Management Center
Una falla di sicurezza critica è stata resa pubblica da Cisco nel suo software Secure Firewall Management Center (FMC), permettendo potenzialmente a malintenzionati non autenticati di eseguire, a distanza, comandi shell a loro scelta con alti livelli di autorizzazione. La vulnerabilità, identificata come CVE-2025-20265 e a cui è stato assegnato il punteggio CVSS massimo di 10,0, rappresenta una delle falle di sicurezza più gravi scoperte quest’anno nell’infrastruttura firewall di Cisco.
Gli aggressori possono sfruttare questa vulnerabilità inviando credenziali appositamente create durante il processo di autenticazione RADIUS consentendo loro di iniettare comandi shell dannosi che vengono successivamente eseguiti dal dispositivo di destinazione. Ciò che rende questa vulnerabilità particolarmente pericolosa è il fatto che non richiede alcuna autenticazione e può essere sfruttata da remoto tramite la rete.
La vulnerabilità di sicurezza risiede nell’implementazione del sottosistema RADIUS del software Secure FMC di Cisco e colpisce in particolare la fase di autenticazione, in cui l’input dell’utente viene gestito in modo improprio.
La vulnerabilità colpisce specificamente le versioni 7.0.7 e 7.7.0 del software Cisco Secure FMC, ma solo quando l’autenticazione RADIUS è abilitata per l’interfaccia di gestione basata sul web, per la gestione SSH o per entrambe. Le organizzazioni che non utilizzano l’autenticazione RADIUS non sono vulnerabili a questo specifico vettore di attacco.
La vulnerabilità deriva da una convalida insufficiente degli input durante il processo di verifica delle credenziali, creando un’opportunità per attacchi di iniezione di comandi quando il sistema elabora le richieste di autenticazione inviate al server RADIUS configurato.
Cisco
ha rilasciato aggiornamenti le patch che risolvono la vulnerabilità e consiglia vivamente di applicare immediatamente le patch a tutti i sistemi interessati.

Arriva la Fidanzata Robot! la nuova frontiera della tecnologia made in Cina
Mentre l’ascesa dei robot in Cina, il più grande mercato e produttore di robot al mondo, sta attirando l’attenzione dell’industria globale dell’informatica (IT), l’emergere di un “robot fidanzata” sta creando scalpore. Questo piccolo robot, modellato su una giovane donna, può cantare e ballare come un gruppo di ragazze e persino impegnarsi in scambi emotivi. È stato recentemente venduto per circa 2 milioni di won a un’asta (circa 2000 euro).
Secondo media cinesi come Kwai Technology, l’azienda di robotica con sede a Shanghai Lingdong Robotics ha recentemente lanciato il suo primo prodotto robotico, il robot umanoide “NIA-F01” (nome cinese: “Nian”), al prezzo di 9.999 yuan (circa 1500 euro).
“Nian” è un robot da tavolo di 56 cm con l’aspetto di una giovane donna snella. Dotato di vista, udito e tatto, può percepire le parole e le espressioni facciali dell’utente, consentendo la comunicazione emotiva. La superficie del robot è ricoperta da un materiale in silicone che risulta molto simile alla pelle, mentre il suo scheletro è suddiviso in un totale di 34 articolazioni, che gli consentono di muovere il corpo liberamente.
Una caratteristica degna di nota è che gli utenti possono “personalizzare” il carattere del robot che desiderano. Attraverso un telaio auto-sviluppato, gli utenti possono cambiare il viso, l’acconciatura, gli abiti, ecc. a seconda dei propri gusti, e possono anche implementare il tutto inserendo una voce umana, linguaggio, movimenti, personalità, ecc. Gli utenti possono creare un “robot fidanzata personalizzato” in base ai propri gusti.
Lingdong Robot ha presentato “Nian” come “il primo robot desktop personalizzato al mondo con intelligenza artificiale“. Inoltre, alla “World Robot Conference (WRC) 2025”, tenutasi a Pechino dall’8 al 12, ha anche presentato il “primo gruppo di ragazze robot al mondo”, in cui diverse “Nian” hanno imparato canzoni e balli di gruppo e li hanno ballati e cantati direttamente.
Lingdong Robot ha attirato nuovamente l’attenzione quando ha messo “Nian” all’asta su una piattaforma. Lingdong Robot aveva fissato l’offerta minima a 1 won, ma “Nian” è stata venduto all’asta quel giorno per 15.800 yuan (circa 2 milioni di won), superando il prezzo di vendita (9.999 yuan).
I media locali hanno riferito che l’emergere di una “fidanzata robot” è un misto di attesa e scetticismo nel settore IT cinese.
I media e i blog tecnologici cinesi nutrono grandi aspettative per il futuro della robotica, considerando che non solo i robot che sostituiscono le attività umane, ad esempio quelli per l’assistenza clienti e la preparazione culinaria, ma anche quelli in grado di rispondere ai bisogni emotivi degli utenti, come i robot compagni e i robot amici, potrebbero costituire una novità importante nel campo della robotica.
I blog e le testate online cinesi si soffermano sulle potenzialità future dei robot che vanno oltre la semplice sostituzione dell’uomo nelle mansioni lavorative, prendendo in considerazione anche quelli capaci di interazione emotiva, ossia i robot amici e i robot da compagnia, che potrebbero rinnovare profondamente il panorama della robotica.

Vulnerabilità critica in Apache Tomcat da aggiornare, altrimenti il server può andare in DoS
Una falla di sicurezza critica è stata individuata nell’implementazione HTTP/2 di Apache Tomcat. Questa vulnerabilità permette a malintenzionati di effettuare attacchi di tipo denial-of-service (DoS) dannosi sui server web.
La vulnerabilità, monitorata con la CVE-2025-48989 e soprannominata attacco “Made You Reset“, colpisce diverse versioni del popolare container dj servlet Java e pone rischi significativi per le applicazioni web in tutto il mondo. La falla di sicurezza, classificata come grave, colpisce le versioni di Apache Tomcat da 11.0.0-M1 a 11.0.9, da 10.1.0-M1 a 10.1.43 e da 9.0.0.M1 a 9.0.107.
La vulnerabilità è stata identificata dai ricercatori di sicurezza Gal Bar Nahum, Anat Bremler-Barr e Yaniv Harel dell’Università di Tel Aviv, che hanno reso noti i loro risultati il 13 agosto 2025. Anche le vecchie versioni ormai fuori produzione potrebbero essere vulnerabili, con il rischio di colpire migliaia di server web in tutto il mondo.
L’attacco “Made You Reset” sfrutta le debolezze nell’implementazione del protocollo HTTP/2 di Tomcat, prendendo di mira il meccanismo di ripristino della connessione. Se eseguito correttamente, l’attacco si manifesta come un OutOfMemoryError, che fa sì che il server preso di mira esaurisca le risorse di memoria disponibili e non risponda più alle richieste legittime.
La vulnerabilità risiede nel modo in cui Tomcat gestisce i ripristini dei flussi HTTP/2 e la gestione delle connessioni. Gli aggressori possono creare richieste HTTP/2 dannose che costringono il server ad allocare risorse di memoria eccessive senza rilasciarle correttamente. Questo comportamento di perdita di memoria può essere attivato ripetutamente, fino a sovraccaricare il pool di memoria disponibile del server e innescare una condizione di negazione del servizio.
Il vettore di attacco sfrutta la funzionalità di multiplexing HTTP/2, grazie alla quale più flussi possono essere elaborati simultaneamente su una singola connessione TCP.
Manipolando i frame di ripristino del flusso e la gestione dello stato di connessione, gli aggressori possono forzare Tomcat a mantenere numerose connessioni semiaperte o stati di flusso incompleti, con conseguente esaurimento delle risorse.

Rediscovering Microsoft’s Oddball Music Generator From The 1990s
There has been a huge proliferation in AI music creation tools of late, and a corresponding uptick in the number of AI artists appearing on streaming services. Well before the modern neural network revolution, though, there was an earlier tool in this same vein. [harke] tells us all about Microsoft Music Producer 1.0, a forgotten relic from the 1990s.
The software wasn’t ever marketed openly. Instead, it was a part of Microsoft Visual InterDev, a web development package from 1997. It allowed the user to select a style, a personality, and a band to play the song, along with details like key, tempo, and the “shape” of the composition. It would then go ahead and algorithmically generate the music using MIDI instruments and in-built synthesized sounds.
As [harke] demonstrates, there are a huge amounts of genres to choose from. Pick one, and you’ll most likely find it sounds nothing like the contemporary genre it’s supposed to be recreating. The more gamey genres, though, like “Adventure” or “Chase” actually sound pretty okay. The moods are hilariously specific, too — you can have a “noble” song, or a “striving” or “serious” one. [harke] also demonstrates building a full song with the “7AM Illusion” preset, exporting the MIDI, and then adding her own instruments and vocals in a DAW to fill it out. The result is what you’d expect from a composition relying on the Microsoft GS Wavetable synth.
Microsoft might not have cornered the generative music market in the 1990s, but generative AI is making huge waves in the industry today.

Calibration, Good Old Calibration
Do you calibrate your digital meters? Most of us don’t have the gear to do a proper calibration, but [Mike Wyatt] shares his simple way to calibrate his DMMs using a precision resistor coupled with a thermistor. The idea is to use a standard dual banana plug along with a 3D-printed housing to hold the simple electronics.
The calibration element is a precision resistor. But the assembly includes a 1% thermistor. In addition to the banana plugs, there are test points to access the resistor and another pair for the thermistor.
In use, you plug the device into the unit you want to test. Then you clip a different temperature sensor to the integrated thermistor. Because the thermistor is in close proximity to the meter’s input, it can tell the difference between the ambient temperature and the meter. [Mike] says the bench meters get warmer than hand-held units.
This is, of course, not a perfect setup if you are a real metrology stickler. But it can be helpful. [Mike] suggests the precision resistor be over 100 ohms since anything less really isn’t a candidate for a precision measurement with two wires. Debating over calibration? We do that, too.
Bench-Top Wireless Power Transmission
[mircemk] has been working on wireless power transmission. Using a Class-E Tesla coil with 12 turns on the primary and 8 turns on the secondary and a 12 volt input he can send a few milliwatts to power an LED over a distance of more than 40 centimeters or power a 10 watt bulb over a distance of about 10 centimeters. With the DC input set at 24 volts the apparatus can deliver 5 watts over a distance of a few centimeters and a light is still visible after separating the primary and secondary coils by more than 30 centimeters.
There are many types of Tesla coil and we can’t go into the details here but they include Spark-Gap Tesla Coils (SGTC) and Solid-State Tesla Coils (SSTC), among others. The Class-E coil demonstrated in this project is a type of SSTC which in general is more efficient than an SGTC alternative.
Please bear in mind that while it is perfectly safe to watch a YouTube video of a person demonstrating a functional Tesla coil, building your own is hazardous and probably not a good idea unless you really understand what you’re doing! Particularly high voltages can be involved and EMI/RFI emissions can violate regulations. You can damage your body with RF burns while not feeling any pain, and without even knowing that it’s happening.

Pirate Candidate Announcement: Blase Henry for AZ’s 17th Legislative District
The United States Pirate Party is excited to announce our first of many candidates for the 2026 election cycle: AZPP Captain Blase Henry shall be running for Arizona’s 17th Legislative District!
Blase has been a rising star within the ranks of the United States Pirate Party, and with this announcement, he is officially the first Pirate we will be backing during the 2026 elections.
If elected, future State Rep. Henry has laid out to us some of the bills he plans on introducing, including but not limited to:
– A digital Bill of Rights for Arizona
– A bill banning ID requirement/age verification laws on the internet, AI or otherwise
– A bill similar to the “Stop Killing Games” initiative of Europe, aiming to protect video game consumers and players
– A bill that prevents internet service providers from sharing your data without your consent and make it so police need a warrant for your data
We are excited to share what will be the first of many Pirate candidates. Some candidates will appear on the ballot as independents, some as members of major parties and some, if they are so fortunate, will have “Pirate” next to their name on the ballot. No matter what it says next to their name on the ballot, we will throw our support behind our Pirate candidates.
NOTE: the US Pirate Party recently endorsed the gubernatorial campaign of Timothy Grady for Ohio. Timothy Grady is an independent candidate but is not officially a Pirate Party candidate. Blase Henry is the first official candidate announced from the US Pirate Party.
To quote Blase Henry himself: “Let’s Hoist the Colours and Join the Pirate Revolution! For if Buying isn’t Ownership, then Piracy isn’t Theft!”
You can visit his campaign website here, or if you’re an AZ resident, you can help get Blase on the ballot here.
Blase Henry, Victory is Arrrs

DIY Wind Turbine Gets a 3-Phase Rectifier
[Electronoobs] is using some brushless motors to make a DIY wind turbine. His recent video isn’t about the turbine itself, but a crucial electronic part: the three-phase rectifier. The reason it is so important is due to the use of brushless motors. Normal motors are not ideal for generating power for several reasons, as explained in the video below.
The brushless motors have three windings and generate three outputs, each out of phase with the others. You can’t just join them together because they are 120 degrees out of phase. But a special rectifier can merge the inputs efficiently and output a low-ripple DC voltage.
The rectifier will have to handle a lot of power, so it uses beefy devices with heat sinks. The design is very similar to a full-wave bridge rectifier, but instead of two legs, each with two diodes, this one has three legs. This is still not as efficient as you would like. A synchronous rectifier would be even more efficient but also more complicated.
Still, we have no doubt the board will do its job. We’re anxious to see the turbine come together. Want to build your own? Maybe start smaller. Too big? You can strip it down even further.

2025 One Hertz Challenge: Blinking An LED With The Aid Of Radio Time
If you want to blink an LED once every second, you could use just about any old timer circuit to create a 1 Hz signal. Or, you could go the complicated route like [Anthony Vincz] and grab 1 Hz off a radio clock instead.
The build is an entry for the 2025 One Hertz Challenge, with [Anthony] pushing himself to whip up a simple entry on a single Sunday morning. He started by grabbing a NE567 tone decoder IC, which uses a phase-locked loop to trigger an output when detecting a tone of a given frequency. [Anthony] had used this chip hooked up to an Arduino to act as a Morse decoder, which picked up sound from an electret mic and decoded it into readable output.
However, he realized he could repurpose the NE567 to blink in response to output from radio time stations like the 60 KHz British and 77.5 KHz German broadcasts. He thus grabbed a software-defined radio, tuned it into one of the time stations, and adjusted the signal to effectively sound a regular 800 Hz tone coming out of his computer’s speakers that cycled once every second. He then tweaked the NE567 so it would trigger off this repetitive tone every second, flashing an LED.
Is it the easiest way to flash an LED? No. It’s complicated, but it’s also creative. They say a one hertz signal is always in the last place you look.

For Americans Only: Estimating Celsius and Other Mental Metrics
I know many computer languages, but I’ve struggled all my life to learn a second human language. One of my problems is that I can’t stop trying to translate in my head. Just like Morse code, you need to understand things directly, not translate. But you have to start somewhere. One of the reasons metric never caught on in the United States is that it is hard to do exact translations while you are developing intuition about just how hot is 35 °C or how long 8 cm is.
If you travel, temperature is especially annoying. When the local news tells you the temperature is going to be 28, it is hard to do the math in your head to decide if you need a coat or shorts.
Ok, you are a math whiz. And you have a phone with a calculator and, probably, a voice assistant. So you can do the right math, which is (9/5) x °C + 32. But for those of us who can’t do that in our heads, there is an easier way.
Field Expedient
Close enough for a quick estimate
Most of us can’t multiply by 9/5 in our heads. But 9/5 is very nearly two. So if you double the Celsius temperature, you are halfway there. Of course, the number will be too high. But to make up for it, instead of adding 32, just add 30. For weather temperatures, this gives you a ballpark estimate. For 0 °C, you get 30 °F instead of 32. For 20 °C, you get 70 °F instead of 68. For 35 °C, you get 100 °F instead of 95. All close enough.
If you want to flip the error as the temperature goes up, you can remember to add 25 instead of 30 if the temperature is more than, say 25 °C. Then 35 °C gives you 95 °F on the dot, although other temperatures will still have some error, of course.
The error gets worse as the temperature rises, but it has to get fairly high before it gets useless. For example, my AMD CPU is currently at 48 °C. Using the +25 estimate, that’s 121 °F, instead of the correct 118. But maybe it won’t help you set up your metal smelting furnace.
Other Estimates
Centimeters to inches the easy way.
This is a useful way to embrace metric. Find rough estimates for units you deal with. For example, 2.54 cm/inch is not the easiest thing to apply. But if you remember that 5 cm is about 2 in, that works well. So a 160 mm rod is 16 cm. If you think of that as 3 x 5 + 1, you’ll know it is 6 inches plus an extra centimeter. The right answer is about 6.3 inches. Not close enough to start cutting things, but it does give you a feel for how big a thing you are talking about.
If you lived through the time when gasoline in the US went from less than $1/gallon to over, you might remember that many gas stations switched to liters because the pumps couldn’t be set for a dollar. The reason is a liter is very nearly a quart, and there are four quarts to a gallon. So 12 liters is practically 12 quarts or 3 gallons. This turns out to be very close.
Kilograms and kilometers are a bit trickier. The right way to imprecisely convert kilograms to pounds is to multiply by 2.2. But a nice mental math trick is to double it. Then remove the last digit and add the rest back in to the whole result. Then put the last digit you removed after the decimal point. So 8 kg would be 16+1 (throw away the six) or 17 pounds. Then put the 0.6 in for the correct answer of 17.6 pounds. Of course, the conversion factor isn’t exactly 2.2, but that’s what most people use anyway. If you are trying to be scientifically accurate, none of this is going to help you.Estimating kilometers.
The factor for kilometers is roughly 0.6 km/mile or 1.6 miles/km. If you halve the kilometers, that will get you a fairly low estimate. So 35 km (21.7 miles) is easy to guess as more than 17.5 miles. That’s a pretty big difference, though. But if you then add 10% of the 35 back (3.5) you get 21 miles which is close.
Advice
I’m not trying to say that these rule-of-thumb tricks are good when you need an exact answer. But they are handy when you simply want a gut feel over some measure. Over time, you’ll just naturally know that 35 °C is summer-weather hot and you need more than a coffee mug to hold 3 liters.
Do you have a favorite fast conversion back or forth from metric? Share it in the comments. Americans love their strange measuring system. Turns out, some of the reasons we didn’t get metric was due to pirates, as you can see in the video below.

3D Printing a Self-cleaning Water Filter
No one likes cleaning out water spouts. [NeedItMakeIt] wanted to collect rainwater and was interested in using a Coanda filter that those used on hydroelectric plants to separate out debris. Ultimately, he decided to design his own and 3D print it.
The design uses a sloping surface with teeth on it to coax water to go in one direction and debris to go in another. It fits into a typical spout, and seems like it works well enough. Some commenters note that varying volumes of rain and different types of debris behave differently, which is probably true. However, there are similar commercial products, so you’d guess there would be some value to using the technique.
The water pushes the debris off the slope, so you end up losing a little water with the debris. So as always, there’s a trade-off. You can see in the video that if the water flow isn’t substantial, the debris tends to stall on the slope. Could the filter be improved? That was the point in trying a second design.
It wasn’t a big improvement. That’s where there’s a plot twist. Well, actually, a literal twist. Instead of making a flat slope, the new design is a conic shape with a spiral channel. That improved flow quite a bit. We weren’t clear from the video of exactly where the debris was going with the last version.
Usually, when we think of the Coanda effect, we are thinking aerodynamics. It can be quite uplifting.

How The Widget Revolutionized Canned Beer
Walk into any pub and order a pint of Guinness, and you’ll witness a mesmerizing ritual. The bartender pulls the tap, fills the glass two-thirds full, then sets it aside to settle before topping it off with that iconic creamy head. But crack open a can of Guinness at home, and something magical happens without any theatrical waiting period. Pour it out, and you get that same cascading foam effect that made the beer famous.
But how is it done? It’s all thanks to a tiny little device that is affectionately known as The Widget.
Beer Engineering

In 1959, draught Guinness diverged from other beers. The pints served from the tap at the pub were charged with a combination of nitrogen gas and carbon dioxide, rather than just carbon dioxide alone. Nitrogen is less soluble in beer than carbon dioxide, and low temperatures and higher pressures are required to get it to stay in the fluid. Charging the beer in this way, and then forcing it through a tap with a restrictor plate with many fine holes, allows the pouring of a beer with small, fine bubbles. This is what gives Guinness its signature smooth, creamy texture and characteristic dense head. The lower carbon dioxide level also contributes to the flavor, removing some of the sharp taste present in regular carbonated beers.
When Guinness started using the nitrogenation method, it quickly gained popularity and became the default way to serve the draught beer. The problem was that it wasn’t initially practical to do the same for bottled Guinness. Without being poured through the fine holes of a special tap under pressure, it wasn’t possible to create the same foamy head. Bottled Guinness thus remained carbonated in the traditional manner, and it was thus very much unlike the draught beer served at the pub. The desire was to produce a better version—”bottled draught Guinness” was a term often bandied about. The company experimented with a variety of methods of serving nitrogenated Guinness from a bottle or can. It even sold some bottles with a special “initiator” syringe to generate head in select markets, but it was all too clumsy to catch on with the beer drinking public. A better solution was needed.The modern floating Guinness widget, pictured in a can that has been cut open. Credit: Duk, CC BY SA 3.0
The modern widget was developed as the technological solution to this fundamental problem in beverage physics. Guinness tackled this challenge by essentially putting a tiny pressure vessel inside the larger pressure vessel of the can itself. The widget is a small plastic sphere, hollow inside, with a tiny hole on the surface. The widget and beer are placed inside the can on the production line. Liquid nitrogen is then added, before the can’s lid is sealed. The can is then inverted as the liquid nitrogen quickly boils off into a gas. This effectively fills the widget with gaseous nitrogen under pressure, often along with a small amount of beer. It’s a charged pressure vessel lurking inside the can itself.
The magic happens when the beverage is served. When you crack open the can, the pressure inside drops rapidly to atmospheric pressure. The nitrogen under pressure in the widget thus wants to equalize with the now lower-pressure environment outside. Thus, the nitrogen sprays out through the tiny hole with tremendous force, creating countless microscopic bubbles that act as nucleation sites for the rest of the nitrogen dissolved in the surrounding beer. As the beer is poured into a glass, a foamy head forms, mimicking the product served fresh from the tap at the local pub.
Today’s widget, first marketed in 1997, is the floating sphere type, but the original version was a little different. The original widget launched in 1989 was a flat disc, which was mounted in the bottom of the can, but fundamentally worked in the same way. However, it had a tendency to cause rapid overflowing of the beer if opened when warm. The floating spherical widget reduced this tendency, though the precise engineering reasons why aren’t openly explained by the company. The fixed widget actually had a surprise return in 2020 due to COVID-19 supply chain issues, suggesting it was still mostly fit for purpose in the brewery’s eyes.
The key to the widget’s performance is in the filling and the construction. It’s important to ensure the widget is filled with pressurized gas, hence the inversion step used in the filling process. If the pressurized nitrogen was allowed to simply sit in the empty space in the top of the can, it would just vent out on opening without making any head. The orifice size on the widget is also critical. Too large, and the pressure equalizes too quickly without creating the necessary turbulence. Too small, and insufficient gas and beer volume flows through to generate adequate nucleation. The widget as it stands today is the result of much research and development to optimize its performance.A finned “rocket” widget as used in Guinness beer bottles. Credit: Joeinwap, CC0
Further different widget designs have emerged over the years. The company had mastered draught Guinness in a can, though it needed to be poured into a glass to be drank properly. The company later looked to create draught Guinness that could be drank straight from the bottle. This led to the creation of the “rocket widget.” It worked largely in the same way, but was designed to float while remaining in the correct orientation inside the neck of the bottle. Fins ensured it wouldn’t fall out of the bottle during drinking. It would charge the beer with bubbles when first opened, and continue to boost the head to a lesser degree each time the bottle was tilted for a sip.
Guinness could have left this problem unsolved. It could have remained a beautiful tap-based beer, while selling its lesser carbonated products in bottles and cans for home consumption. Instead, it innovated, finding a way to create the same creamy tap-poured experience right out of the can.
The next time you crack open a widget-equipped can and watch that mesmerizing cascade of bubbles, you’re witnessing a masterpiece of beverage engineering that took years to perfect. It’s a reminder that sometimes the most elegant engineering solutions hide in the most ordinary places, waiting for someone clever enough to recognize that a tiny plastic ball could revolutionize how we experience beer outside the pub.
Dopo Darcula arriva Magic Mouse: il nuovo incubo del phishing ruba 650.000 carte al mese
Dopo la chiusura della piattaforma di phishing Darcula e del software Magic Cat utilizzato dai truffatori, la soluzione Magic Mouse ha guadagnato popolarità tra i criminali. Secondo gli specialisti di Mnemonic, Magic Mouse contribuisce già al furto di dati da almeno 650.000 carte bancarie al mese.
Recentemente abbiamo parlato del lavoro di Darcula e dell’indagine condotta dagli esperti di Mnemonic. Questa piattaforma PhaaS (phishing-as-a-service) ha preso di mira utenti Android e iPhone in oltre 100 paesi. Il servizio criminale ha utilizzato 20.000 domini che imitavano marchi noti per rubare credenziali.
Secondo gli analisti, gli operatori di Darcula sono stati responsabili del furto di 884.000 carte bancarie e le vittime di hacker in tutto il mondo hanno cliccato su link dannosi ricevuti tramite messaggi di testo 13 milioni di volte.
Poco dopo l’attività di Darcula è cessata, ma come hanno spiegato i ricercatori di Mnemonic al DEF CON, un altro servizio di phishing simile sta guadagnando popolarità tra i criminali informatici.
Gli esperti ricordano che il software Magic Cat ha svolto un ruolo chiave nel lavoro di Darcula. Ora Magic Cat è stato sostituito da una piattaforma simile, Magic Mouse, la cui popolarità è aumentata notevolmente dopo la chiusura di Darcula.
Gli esperti ritengono che Magic Mouse sia un’operazione nuova, con sviluppatori diversi dietro. Non è quindi correlato a Darcula. Tuttavia, l’attuale successo di Magic Mouse è dovuto in gran parte al fatto che nuovi operatori si sono appropriati dei kit di phishing che hanno reso così popolare il software del suo predecessore.
Questi kit contengono centinaia di modelli di siti di phishing che Magic Cat ha utilizzato per imitare pagine web legittime di importanti colossi tecnologici, noti servizi al consumatore e servizi di consegna. Tutti questi siti sono stati progettati per indurre le vittime a fornire i dati della propria carta di credito.
Sebbene Magic Mouse sia già popolare e potrebbe diventare ancora più pericoloso di Magic Cat in futuro, portando ai suoi operatori milioni di dollari di profitti (sotto forma di fondi rubati alle vittime), i ricercatori osservano che le forze dell’ordine “non riescono a vedere” oltre alcune segnalazioni isolate di frode. In altre parole, nessuno attualmente considera Magic Mouse una campagna fraudolenta su larga scala.
Allo stesso tempo, Mnemonic ritiene che gran parte della responsabilità dell’esistenza e della prosperità di tali schemi fraudolenti ricada sulle aziende tecnologiche e sui giganti della finanza, che continuano a rendere difficile ai truffatori l’utilizzo di carte rubate.
