Source code for BadUSB vulnerability posted on GitHub

usb-flash-drive(LiveHacking.Com) – Back in August, security researchers  Karsten Nohl and Jakob Lell demonstrated how a USB device can be reprogrammed and used to infect a computer without the user’s knowledge. Dubbed BadUSB, the pair published their findings during the Black Hat conference, however they did not publish the source code or the reversed engineered firmware needed to perform the attack. Nohl and Lell said they did not release code in order to give firms making USB-controller firmware time to work out how to combat the problem.

Now two other researchers, Adam Caudill and Brandon Wilson have done their own research on BadUSB and produced code that can be used to exploit it. The source-code can be found on Github. Unlike Nohl and Lell, Caudill and Wilson think it is in the public’s interest to release the source code for public consumption.

“We’re releasing everything we’ve done here, nothing is being held back,” said Mr Wilson during his presentation at DerbyCon. “We believe that this information should not be limited to a select few as others have treated it. It needs to be available to the public.”

The BBC contacted Karsten Nohl about the new release, he said that “full disclosure” can motivate USB device makers to improve the security on their devices. However he also noted that the problem with BadUSB is not one particular device but rather, “the standard itself is what enables the attack and no single vendor is in a position to change that.” He added that, “it is unclear who would feel pressured to improve their products by the recent release.”

According to the GitHub page for the new source-code the following devices can be reprogrammed and used as attack vectors:

  • Patriot 8GB Supersonic Xpress
  • Kingston DataTraveler 3.0 T111 8GB
  • Silicon power marvel M60 64GB
  • Toshiba TransMemory-MX™ Black 16 GB
  • Patriot Stellar 64 Gb Phison
