Description: 

This memory-resident worm spreads via network shares. It attempts to drop a copy of itself to the shared folders within the network, if they are not password-protected.

It also exploits the Remote Procedure Call (RPC) Distributed Component Object Model (DCOM) vulnerability to propagate across networks. For more information about these Windows vulnerabilities, please refer to the following Microsoft Web pages:

It has backdoor capabilities, which allow it to perform port scanning activities in order to connect with the malware author. It also uses Secure Socket Layer (SSL) so that it can encrypt the packets that it sends to avoid detection. This worm also steals the Microsoft Windows product ID and the CD keys of popular game applications.

It also has the ability to terminate processes, which are usually related to antivirus, firewall, and system applications. It also modifies the HOSTS file to prevent the user from accessing certain Web sites.

It runs on Windows NT, 2000, and XP.

TECHNICAL DETAILS


Size of malware: 161,280 Bytes

Initial samples received on: Jan 14, 2005

Payload 1: Steals CD keys

Payload 2: Compromises system security

Payload 3: Redirects users to local machine

Payload 4: Terminates processes

Details:

Installation and Autostart Technique

Upon execution, this memory-resident worm drops a copy of itself in the Windows system32 folder as the following file:

    GNKSVC32.EXE

It then adds the following registry entries to enable its dropped copy to run at every Windows startup:

HKEY_LOCAL_MACHINE\Software\Microsoft
Windows\CurrentVersion\Run
Gekio Startups = "gnksvc32.exe"

HKEY_LOCAL_MACHINE\Software\Microsoft\
Windows\CurrentVersion\RunServices
Gekio Startups = "gnksvc32.exe"

After installing itself on the system and launching its dropped copy into memory, it deletes the executed worm file.

Network Propagation and Exploits

This worm spreads via network shares. It attempts to drop a copy of itself to the following shared folders in the network, if they are not password-protected:

  • ADMIN$
  • Print$

This worm may also take advantage of the Remote Procedure Call (RPC) Distributed Component Object Model (DCOM) vulnerability present on Windows XP systems, in order to spread across the network. This vulnerability allows an attacker to gain full access and execute any code on a target machine, leaving it compromised.
