Overview

This is a trojan detection. Unlike viruses, trojans do not self-replicate. They are spread manually, often under the premise that they are beneficial or wanted. The most common installation methods involve system or security exploitation, and unsuspecting users manually executing unknown programs. Distribution channels include email, malicious or hacked web pages, Internet Relay Chat (IRC), peer-to-peer networks, etc.

Aliases

• Backdoor.Win32.IRCBot.br (Kaspersky)

• Troj/Stinx-A (Sophos)

Characteristics

This IRC bot trojan was mass-spammed on June 13, 2005 attached to an email message as follows:

Subject: Fw: Photo approval needed
Body:

When run, this trojan attempts to connect to two IRC servers on TCP port 6667:

• 69.31.78.132
• 69.31.73.179
• 66.252.2.190
• irc.skene.net

The trojan allows a remote attacker to download and execute arbitrary programs.

Symptoms

This trojan copies itself to the WINDOWS SYSTEM directory as svcmfte32.exe and creates 2 registry run keys to load itself at startup:

• HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
  Run "MainStart" = svcmfte32.exe
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
  Run "MainStart" = svcmfte32.exe

The trojan uses NETSH to add itself to the Windows Firewall allowed programs list.

Method of Infection

This trojan was mass-spammed as an email attachment.  Manually running the attachment infects the local machine.

Removal

All Users:
Use current engine and DAT files for detection and removal.

Modifications made to the system Registry and/or INI files for the purposes of hooking system startup, will be successfully removed if cleaning with the recommended engine and DAT combination (or higher).

Additional Windows ME/XP removal considerations
