Another Biometric Flash Drive Vulnerability

leave a comment »

Here’s a link to an article about a number of easy to crack biometric flash drives brought to light by the folks at Heise Online. This vulnerability in two of the controllers from Afa Technology, a.k.a. Afatech, effects flash drives from the following vendors:

  • 9Pay
  • A-Data
  • Transcend

Given that flash drive vendors often use controller chips manufactured by third parties, it is likely that additional biometric flash drive vendors harbor this same vulnerability. Afatech recently merged with another Taiwan-based IC company, ITE Tech, and press releases indicate their controller design team will be integrated into a similar R&D team at ITE Tech. Therefore, any purchases of biometric flash drives from vendors that use controllers from Afatech or ITE Tech should be scrupulously reviewed.

As always, stay safe and avoid a false sense of security.
