Linux & Unix Viruses

Slapper Worm Gets Facelift

Unix-based BBS admins or bloggers beware - the Linux Slapper worm has been given a facelift and this time you're the target. The worm exploits a vulnerability in xmlrpc.php, a file commonly included in BBS and weblog software. A second exploit lies in a vulerability in AWStats, a web hit statistics package. A third exploit leverages a flaw in WebHints, which can lead to remote system access.
Linux Users Beware the Lion

The SANS Institute's Global Incident Analysis Center has issued an alert warning of a Linux worm similar to the Ramen virus but significantly more dangerous. The Lion worm affects Linux machines running the BIND DNS server, versions 8.2, 8.2-P1, 8.2.1, 8.2.2-Px, and all 8.2.3-betas.
The first Windows Linux cross-platform virus discovered

Virus researchers have discovered a new breed of virus that infects both Windows and Linux files on Intel-based Pentium PC's. Considered a proof-of-concept virus, it has not been found in-the-wild. As such, it is not posing a threat to users, but could signal the beginning of a new precedent in virus writing - the cross-platform threat. Within less than a day of discovery, the new virus has already been assigned a number of different names, including Linux.PEElf.2132, W32.Winux, Linux.Winux, W32/Lindose, and W32.PEElf.2132.
