29C3: Travis Goodspeed – writing a thumbdrive from scratch

Posted on Saturday, January 19th, 2013 in hacks, USB, Videos by the machinegeek


In this presentation from the recent 29C3 conference, Travis Goodspeed provides an interesting explanation of his from scratch implementation of a USB Mass Storage disk in user-land Python for the Facedancer board. . He also covers aspects of antiforensics are they relate to thumbdrives. His demo show how a thumbdrive’s own firmware can recognize and defend itself against disk imaging and other forensic tools, wiping itself to an innocent state whenever it detects disk imaging, undeletes, access by the wrong operating system, or the presence a write blocker.

Interesting stuff!

  • KH: Really? They are digital inputs driven by an MCU. The MCU GPIO probably has diode clamps and ESD protection. Have you experienced such failures? Please...
  • KH: Neither. Google "Marco Schweighauser’s 8-bit virtual Javascript CPU" and see the first result. Sounds more like a very limited feature toy CPU.
  • Alan: "8-bit x86 like CPU" - isn't that an 8080, or Z80?
