Researcher Details USB-Based Attack That Circumvents All Known Protective Security Measures
The exploit takes advantage of a flaw that allows a hacker to tamper with the firmware that controls the functions of USB devices such as mice, thumb drives and keyboards.
Because BadUSB resides not in the flash memory storage of USB devices, but in the firmware that controls their basic functions, the attack code can remain hidden long after the contents of the device’s memory would appear to the average user to be deleted. And the two researchers say there’s no easy fix: The kind of compromise they’re demonstrating is nearly impossible to counter without banning the sharing of USB devices or filling your port with superglue.Nohl, along with fellow SR Labs researcher Jakob Lell, will present additional details on this attack during a presentation at the annual Black Hat hacking conference, which will be held next week in Las Vegas. The title of his presentation is "Bad USB - On Accessories that Turn Evil."
“These problems can’t be patched,” says Nohl, who will join Lell in presenting the research at the Black Hat security conference in Las Vegas. “We’re exploiting the very way that USB is designed.”
