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.

Characteristics

This trojan reconfigures Internet Explore to redirect users to a pornographic site.

When run, it modifies the following registry keys:

• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
  URL\DefaultPrefix "(Default)" = http://www.microsoit.com/direct.php?url=
• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
  URL\Prefixes "www" = http://www.microsoit.com/direct.php?url=
• HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main "Start Page" =about:blank

The effect of these modifications is that any address entered, without giving the protocol prefix such as "http://", will redirect users to the porn site "www.microsoit.com". This trojan also changes the start page to the blank page.

It also attempts to create the registry run key as follows, however since it fails to drop itself to C:\config.exe, it may not be effective.

• HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run "cmd32" = C:\configs.exe

Symptoms

• unexpected access to the porn site
• Unexpected blank start page of IE
• Existence of the above registry keys

Method of Infection

Trojans do not self-replicate. They are spread manually, often under the premise that the executable is something beneficial. Distribution channels include IRC, peer-to-peer networks, newsgroup postings, etc.

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
