IRC-Worm.DOS.Loa

Class IRC-Worm
Platform DOS
Description

Technical Details

This is an IRC worm that spreads via mIRC channels. The worm code itself is
a randomly named DOS EXE file. When it is executed, the worm copies itself
with the LOA.EXE name to the Windows directory and registers this file in
the system registry in the auto-run section:


LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionRunServices:
“Life of Agony”=”loa.exe”

When the worm locates the MIRC.INI file, it writes to there several
instructions that disable the mIRC security settings and creates its script
file that contains commands that send the worm’s EXE file to the channel.

The worm manifests itself as anti-virus programs that searche and delete
the DM-Setup mIRC worm (the worm actually does delete DM-Setup
files if they present on disks). It then displays the following messages:


You are about to scan your harddrive for the DMSetup virus, it is
crucial that you run this program without mIRC active, so if you
are still in mIRC at the moment, type /EXIT before you continue.
Press any key if mIRC is not active…

The worm also displays other messages that depend on the current date:
