New Windows Malware Locks Computer in Kiosk Mode

Posted on by

Clever:

A malware campaign uses the unusual method of locking users in their browser’s kiosk mode to annoy them into entering their Google credentials, which are then stolen by information-stealing malware.

Specifically, the malware “locks” the user’s browser on Google’s login page with no obvious way to close the window, as the malware also blocks the “ESC” and “F11” keyboard keys. The goal is to frustrate the user enough that they enter and save their Google credentials in the browser to “unlock” the computer.

Once credentials are saved, the StealC information-stealing malware steals them from the credential store and sends them back to the attacker…

Israel’s Pager Attacks and Supply Chain Vulnerabilities

Posted on by

Israel’s brazen attacks on Hezbollah last week, in which hundreds of pagers and two-way radios exploded and killed at least 37 people, graphically illustrated a threat that cybersecurity experts have been warning about for years: Our international supply chains for computerized equipment leave us vulnerable. And we have no good means to defend ourselves.

Though the deadly operations were stunning, none of the elements used to carry them out were particularly new. The tactics employed by Israel, which has neither confirmed nor denied any role, to hijack an international supply chain and embed plastic explosives in Hezbollah devices have been used for years. What’s new is that Israel put them together in such a devastating and extravagantly public fashion, bringing into stark relief what the future of great power competition will look like—in peacetime, wartime and the ever expanding …

Hacking the “Bike Angels” System for Moving Bikeshares

Posted on by

I always like a good hack. And this story delivers. Basically, the New York City bikeshare program has a system to reward people who move bicycles from full stations to empty ones. By deliberately moving bikes to create artificial problems, and exploiting exactly how the system calculates rewards, some people are making a lot of money.

At 10 a.m. on a Tuesday last month, seven Bike Angels descended on the docking station at Broadway and 53rd Street, across from the Ed Sullivan Theater. Each rider used his own special blue key -­- a reward from Citi Bike—­ to unlock a bike. He rode it one block east, to Seventh Avenue. He docked, ran back to Broadway, unlocked another bike and made the trip again…

FBI Shuts Down Chinese Botnet

Posted on by

The FBI has shut down a botnet run by Chinese hackers:

The botnet malware infected a number of different types of internet-connected devices around the world, including home routers, cameras, digital video recorders, and NAS drives. Those devices were used to help infiltrate sensitive networks related to universities, government agencies, telecommunications providers, and media organizations…. The botnet was launched in mid-2021, according to the FBI, and infected roughly 260,000 devices as of June 2024.

The operation to dismantle the botnet was coordinated by the FBI, the NSA, and the Cyber National Mission Force (CNMF), according to a press release dated …

Remotely Exploding Pagers

Posted on by

Wow.

It seems they all exploded simultaneously, which means they were triggered.

Were they each tampered with physically, or did someone figure out how to trigger a thermal runaway remotely? Supply chain attack? Malicious code update, or natural vulnerability?

I have no idea, but I expect we will all learn over the next few days.

EDITED TO ADD: I’m reading nine killed and 2,800 injured. That’s a lot of collateral damage. (I haven’t seen a good number as to the number of pagers yet.)

EDITED TO ADD: Reuters writes: “The pagers that detonated were the latest model brought in by Hezbollah in recent months, three security sources said.” That implies supply chain attack. And it seems to be a large detonation for an overloaded battery…

Python Developers Targeted with Malware During Fake Job Interviews

Interesting social engineering attack: luring potential job applicants with fake recruiting pitches, trying to convince them to download malware. From a news article

These particular attacks from North Korean state-funded hacking team Lazarus Group are new, but the overall malware campaign against the Python development community has been running since at least August of 2023, when a number of popular open source Python tools were maliciously duplicated with added malware. Now, though, there are also attacks involving “coding tests” that only exist to get the end user to install hidden malware on their system (cleverly hidden with Base64 encoding) that allows remote execution once present. The capacity for exploitation at that point is pretty much unlimited, due to the flexibility of Python and how it interacts with the underlying OS…
