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-CCG

• TrojanSpy.Win32.Briss (AVP)

Characteristics

This is a trojan that installs itself on the victim's system for the purpose of logging any keys pressed and sending this log to a remote computer.  By doing this, it allow the attacker to grab sensitive information, including usernames and passwords. 

Note:   This was earlier detected as BackDoor-CCG, but has since been renamed to KeyLog-Briss.

Installation

Upon execution, the trojan modifies the registry to automatically load itself into memory at the next startup.

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
"systray" = C:\test\A.EXE

Note:   The keylogging behavior was not observed during testing. 

Symptoms

Presence of the file and registry entry mentionned 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, email, etc.

Removal

AVERT recommends to always use latest DATs and engine. This threat will be cleaned if you have this combination.
