Beware Of Bogus Audio And Video Files

When it comes to downloading music and video files what you see is not always what you get. It’s emerged that organisations associated with the RIAA have been polluting p2p file sharing services with bogus Windows Media files (WMA) containing ads and adware. has published news of contentious Windows Media files found on file sharing networks like Kazaa following an alert from a PC World reader. The files look like authentic music and video downloads but contain code that can spawn a string of pop-up ads and install adware using Internet Explorer.

According to PC World, “Using a packet analysis tool called Etherpeek, we determined that each media file loaded a page served by a company called Overpeer (owned by Loudeye). That page set off a chain of events that led to the creation of several Internet Explorer windows, each containing a different ad or adware.” Unfortunately this exploit may still affect you even if Internet Explorer is not your default browser.

Overpeer has worked with record companies since 2002 providing services that flood p2p networks with fake audio files that purport to be popular songs in an effort to deter p2p pirates. This division of the operation exploits a DRM loophole via security holes in Microsoft’s Internet Explorer. I wonder how Microsoft and other vendors will react to users avoiding WMA files in the light of malicious hackers exploiting their vulnerabilities?
