Winamp PoC Backdoor and a Zero Day

Listen to your infection? Not necessarily as this backdoor binds cmd.exe on port 24501, but needs to be socially engineered in the form of a plugin for Winamp. Code originally released in December, 2006, see attached screenshot. Not much of a fun here either, but as the folks at SANS point out Winamp doesn't play .MP4 files automatically from a web page, so no chance to have it embedded within popular sites and cause mass outbreaks as we saw it happen with the with ANI exploit code and the WMF one.
