The first trojan using Sony´s rootkit software to hide itself has been discovered by anti-virus companies. The register.co.uk:
“Sony-BMG’s rootkit DRM technology masks files whose filenames start with “$sys$”. A newly-discovered variant of of the Breplibot Trojan takes advantage of this to drop the file “$sys$drv.exe” in the Windows system directory.”
This new Trojan can only be detected by special software like the freeware product Rootkit Revealer. The trojan seems to be spread by fake emails asking business men to verify their picture.
