Another Sony rootkit

F-Secure announced yesterday that it has found another Sony product that installs a rootkit and hidden directory on Windows machines. Last time it was the copy protection associated with music CDs, this time it's software associated with a fingerprint reader for the Sony MicroVault USM-F memory stick, which Sony says is now no longer for sale. The use of the memory stick causes files to be installed into a hidden directory on your hard drive which is hidden from the operating system, including antivirus scanning. This means that, like the hidden directory created by the CD copy protection scheme, the directory can be used by other malicious software to hide itself.
