Denial of Service



If the local system date is between April 14th and April 23rd when the worm starts up, it targets the following remote servers in a denial of service attack:



http://www.keygen.us

http://www.freemule.net

http://www.kazaa.com

http://www.emule.de

http://www.cracks.am

System Changes



The worm installs itself on the victim machine as SYMAV.EXE in the Windows directory:



%WinDir%\SymAV.EXE

The following Registry key is added to hook system startup:



HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion

\Run "SymAV" = %WinDir%\SymAV.EXE

A base-64 encoded copy of the worm is saved to disk as F***_YOU_BAGLE.TXT (letters omitted, replaced with *) in the Windows directory:



%WinDir%\f***_you_bagle.txt

Remote Access Component



The worm opens port 6789 (TCP) on the victim machine. This facilitates the downloading and execution of files.
