Security specialists are warning that Sony's MicroVault USB, which is a biometric USB storage device, cloaks driver software in a Windows directory that could be used by malware to avoid detection from security applications.

The fingerprint-recognition software packaged with Sony's Microvault USB installs itself as hidden files on the user's system under the "c:\windows\" directory

F-Secure security expert, Mika Tolvanen, reported that it is possible to enter the hidden directory using a Command Prompt and from there create and run new hidden files.

"Files in this directory are also hidden from some antivirus scanners — as with the Sony BMG DRM case — depending on the techniques employed by the antivirus software. It is therefore technically possible for malware to use the directory as a hiding place," said Tolvanen on the F-Secure blog.

Sony claims the rootkit-like behaviour of a device driver used to run its biometric Micro Vault USB drive was unintentional.

Sony Sweden representative Fredrik Fagerstedt told local press this week that sometimes even actions undertaken with "good will" can go wrong.

Sony admits to USB security flaw

A spokesperson from Sony downplayed the situation: "While relatively small numbers of these models were sold, we are taking the matter seriously and conducting an internal investigation. No customers have reported problems related to situation to date."

Although the models affected are no longer being produced, some can still be found in stock in online stores. Sony said a downloadable fix for the problem would be offered by mid-September.
