Security Bites Podcast: Skype worm jumps apps

This week, CNET.com's Robert Vamosi features guest security researcher Chris Boyd of FaceTime Communications. Boyd says he has discovered a new Skpe-based worm that manages to jump the fence and infect other IM clients such as Trillian, ICQ, AIM, Yahoo Messenger and MSN Messenger. Boyd also talks about his ongoing work with botnets, in particular one network that appears to be using the botnet's spam profits to buy firearms for a Middle East terrorist cell.

Also on the show, Vamosi talks about Apple's almost-monthly patch cycle, addressing 17 flaws in its latest update, including one affecting specially crafted PDF files, as well as fixes for flaws in Bind, Fetchmail and GNU Screen.

And Vamosi discusses a war in Estonia--online. Up to 128 Estonia-based URLs, including government sites, were victims of denial-of-service attacks over a two-week period. At the height, 58 sites were attacked May 9, 2007, which is Victory Day in Russia, where many of the attacks are thought to originate.
