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.ServU-based (AVP)

• Backdoor.ServU.B (Central Command)

• Troj/Vicwor-A (Sophos)

Characteristics

This detection covers a popular FTP server daemon in certain packed formats. The Serv-U FTP daemon is a popular commercial FTP server. However, it has been used in many root kits and other malware for malicious purposes. BackDoor-ZH covers such misuse of this application.

Symptoms

Firewall traffic - Listening TCP Port 43958
Presence of RPCMON.DLL & RPCMON.VXD

Method of Infection

Varies. This remote access trojan is often dropped by other executables or self-extracting archives. Once the FTP server is running, a remote attacker can perform various file system functions.

Removal

All Users:
Use current engine and DAT files for detection. Delete any file which contains this detection.

Additional Windows ME/XP removal considerations
