Sony Rootkit (part two)

Sony has used rootkit-like technology in one of its products - again. The company first made this mistake when some of its music CDs installed DRM software on Windows PCs. Now F-Secure has discovered that the software used with Sony's USB memory sticks, specifically the MicroVault models with fingerprint recognition, features similar sneaky features.

Essentially the software creates a hidden folder to keep its fingerprint authentication data safe. However, adding this kind of feature to a PC is not always the best idea because it can be abused by malicious users or intruders. McAfee has provided an interesting video that demonstrates the trouble this can cause (see below).
