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

• VBS/Parlay

Characteristics

This detection is for a remote proxy trojan. That allows the remote hacker to connect to other systems via the compromised system and so obscure his tracks when either hacking into or attacking a another system.

Installation

Upon execution, the trojan installs itself into the %Sys32Dir% directory as REALUPD.EXE.

For example:

C:\WINDOWS\SYSTEM32\REALUPD.EXE

The following Registry key(s) is/are added to hook system startup:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
Run "Real Player Updater" = "%Sys32Dir%\realupd.exe"

Functionality

Once running on the victim machine, the server component opens a random high numbered socket (above 1024) to accept remote connections. The trojan also attempts to connect to an specific IP address in order to upload the IP address and port number of the compromised system to allow the hacker to know which port to use to connect to the compromised system. At this time this IP address is not accessable.

Symptoms

• A port number above 1024 open and listening
• Existence of the files/Registry keys detailed 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

All Users:
Use specified 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
