Symantec Says new Worm Infects All Three OS’s

Symantec considers the malware to be medium risk, but says it can and does infects Mac, Windows/Vista and Linux.

—The worm was first spotted late last month but at the time, it was not thought to be “in the wild”.

Once opened the OpenOffice file (badbunny.odg) launches a macro that behaves in several different ways depending on the user’s operating system.

On Windows systems, it drops a file called drop.bad which is moved to the system.ini in the user’s mIRC folder, while executing the Javascript virus badbunny.js that replicates to other files in the folder.

On Apple Mac systems, the worm drops one of two Ruby script viruses in files called badbunny.rb and badbunnya.rb.

On Linux systems, the worm drops both badbunny.py as an XChat script and badbunny.pl as a Perl virus.

Symantec rates the worm “Medium Risk”.
