Ramsey Malware

A new malware, called Ramsey, can jump air gaps: ESET said they’ve been able to track down three different versions of the Ramsay malware, one compiled in September 2019 (Ramsay v1), and two others in early and late March 2020 (Ramsay v2.a and v2.b). Each version was different and infected victims through different methods, but at its core, the malware’s… Continue reading Ramsey Malware

Jumping Air Gaps

Nice profile of Mordechai Guri, who researches a variety of clever ways to steal data over air-gapped computers. Guri and his fellow Ben-Gurion researchers have shown, for instance, that it’s possible to trick a fully offline computer into leaking data to another nearby device via the noise its internal fan generates, by changing air temperatures in patterns that the receiving… Continue reading Jumping Air Gaps

Bluetooth Vulnerabilities

A bunch of Bluetooth vulnerabilities are being reported, some pretty nasty. BlueBorne concerns us because of the medium by which it operates. Unlike the majority of attacks today, which rely on the internet, a BlueBorne attack spreads through the air. This works similarly to the two less extensive vulnerabilities discovered recently in a Broadcom Wi-Fi chip by Project Zero and… Continue reading Bluetooth Vulnerabilities

Jumping Airgaps with a Laser and a Scanner

Researchers have configured two computers to talk to each other using a laser and a scanner. Scanners work by detecting reflected light on their glass pane. The light creates a charge that the scanner translates into binary, which gets converted into an image. But scanners are sensitive to any changes of light in a room­ — even when paper is… Continue reading Jumping Airgaps with a Laser and a Scanner

Jumping Air Gaps with Blinking Lights and Drones

Researchers have demonstrated how a malicious piece of software in an air-gapped computer can communicate with a nearby drone using a blinking LED on the computer. I have mixed feelings about research like this. On the one hand, it’s pretty cool. On the other hand, there’s not really anything new or novel, and it’s kind of a movie-plot threat. Research… Continue reading Jumping Air Gaps with Blinking Lights and Drones

Yet Another Government-Sponsored Malware

Both Kaspersky and Symantec have uncovered another piece of malware that seems to be a government design: The malware — known alternatively as "ProjectSauron" by researchers from Kaspersky Lab and "Remsec" by their counterparts from Symantec — has been active since at least 2011 and has been discovered on 30 or so targets. Its ability to operate undetected for five… Continue reading Yet Another Government-Sponsored Malware
