New Worm Transcodes MP3s to Try to Infect PCs

Filed under: — Aviran Mordo

A new kind of malicious software could pose a danger to Windows users who download music files on peer-to-peer networks.

The new malware inserts links to dangerous Web pages within ASF Advanced Systems Format media files.

The possibility of this has been known for a little while but this is the first time we ve seen it done, said David Emm, senior technology consultant for security vendor Kaspersky Lab.

Advanced Systems Format is a Microsoft-defined container format for audio and video streams that can also hold arbitrary content such as images or links to Web resources.

If a user plays an infected music file, it will launch Internet Explorer and load a malicious Web page which asks the user to download a codec, a well-known trick to get someone to download malware.

The actual download is not a codec but a Trojan horse, which installs a proxy program on the PC, Emm said. The proxy program allows hackers to route other traffic through the compromised PC, helping the hacker essentially cover their tracks for other malicious activity, Emm said.

The malware has worm-like qualities. Once on a PC, it looks for MP3 or MP2 audio files, transcodes them to Microsoft s Windows Media Audio format, wraps them in an ASF container and adds links to further copies of the malware, in the guise of a codec, according to another security analyst, Secure Computing.

The .mp3 extension of the files is not modified, however, so victims may not immediately notice the change, according to Kaspersky Lab.

Trend Micro calls the malware “Troj_Medpinch.a,” Secure Computing named it ” “Trojan.ASF.Hijacker.gen” and Kaspersky calls it “Worm.Win32.GetCodec.a.”

SCO ordered to pay Novell for software royalties

Filed under: — Aviran Mordo

The SCO Group has been ordered to pay Novell Inc. more than $2.5 million in royalties in a dispute over the Unix computer operating system.

Wednesday’s award by U.S. District Judge Dale Kimball falls short of the nearly $20 million Novell was seeking. Nonetheless, SCO said it might appeal.

SCO originally brought a lawsuit against Novell in 2004 alleging slander of title. SCO asserted Novell hurt SCO’s business and reputation by denying that Novell sold SCO ownership rights when it allowed SCO to take over the business of servicing Unix technology in 1995.

Novell countersued for license royalties. Kimball ruled last August that SCO didn’t acquire ownership rights to Unix when it bought the licensing and development rights from Novell in 1995. That paved the way for Wednesday’s award.
