Permalink: Vulnerability could affect Sony USB sticks

Researchers from security companies F-Secure and McAfee have discovered that file-cloaking software in high-end Sony memory sticks could make computers vulnerable to hackers.

According to Finnish security software company F-Secure, Sony’s Micro Vault USB memory stick includes software that creates a hidden directory on the computer’s hard drive, a technique also used by a “root kit” hacking tool.

The hidden directory is designed to protect the memory stick’s fingerprint authentication feature from tampering and bypass.

However, F-Secure believes that this could also allow hackers to disguise malicious activity and has criticised Sony’s decision to use a rootkit-like cloaking technique its devices.

Software and files in hidden drives are not visible on screen and can also elude security software.

McAfee researchers have confirmed the vulnerability described by F-Secure.
