But any decent anti-virus tool will catch that type of thing.
We've long known that using USB flash drives can be dangerous, because a virus can be stored as a file on the drive. That will either shine a bright light on the problem, or spawn a cottage industry of hacking USB devices, or both. “We’re exploiting the very way that USB was designed.” Noll and Lell plan to demonstrate their code at the BlackHat 2014 conference to be held on August 7th. “These problems can’t be patched,” says Nohl. This previously unknown vulnerability is part of the USB standard’s design as such, it can’t be eliminated without re-engineering every USB device. It is a collection of malicious apps that can modify any software installed from a USB drive on a target computer completely take over control of an infected PC and even redirect users’ Internet traffic.Įrasing or reformatting the USB drive does not destroy the malware, which hides in the USB device’s firmware that controls the drive’s basic functions. To demonstrate the vulnerability of USB drives, the researchers wrote some proof-of-concept malware (which we can only hope no one copies) called BadUSB.
