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

• Boot.Stonedbootkit (Symantec)

• Rootkit.Win32.Stoned.a (Kaspersky)

Characteristics

StonedBootkit is a Master Boot Record (MBR) infecting trojan. It infects the Master Boot Record on the system hard disk. StonedBootkit can also exhibits characteristics of rootkit stealth-like behavior in that it hooks the system before Windows loads giving it the ability to hide from Windows and other applications running within Windows.

A proof-of-concept installs files under the following folders:

• c:\Stoned
• c:\Stoned\Applications
• c:\Stoned\Drivers
• c:\Stoned\Plugins

When it is done, it displays the following message:

Using a Software Development Kit (SDK), this proof-of-concept trojan can be extended into other applications, drivers, and plugins.

Symptoms

Presence of the folders (and files) mentioned above.

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
