Description: 

This AGOBOT variant is a network worm and a backdoor. It propagates into machines unpatched to the following vulnerabilities:

It attempts to log into systems using a list of user names and passwords. This worm then drops a copy of itself in accessed machines.

It also terminates certain processes and steals CD keys of certain game applications, then sends gathered data to a remote user via mIRC. It also has backdoor capabilities and may execute remote commands in the host machine.

This malware runs on Windows NT, 2000, and XP only.

Installation and Autostart Techniques

Upon execution, the malware drops a copy of itself in the Windows System directory using the following file name:

    SUPPORT3.EXE

It then adds the following entries so that it exectes everytime Windows restarts:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows
CurrentVersion\RunServices
x~{{dybel = "x~{{dy8%nsn"

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows
CurrentVersion\Run
x~{{dybel = "x~{{dy8%nsn"

It also creates the following registry keys and adds information within them in order to add the dropped file as a service that cannot be immediately terminated:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\
Enum\Root\LEGACY_SPPRT

HKEY_LOCAL_MACHINE\System\CurrentControlSet
Services\spprt

Network Propagation and Exploits

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

Read more on this vulnerability from the following link:

This worm looks for vulnerable machines on the network by scanning for random TCP/IP addresses on port 135.

It further uses the RPC Locator vulnerability which affects Windows NT systems and searches for vulnerable Windows NT machines on the network by incrementally scanning TCP/IP addresses on port 445.

More information on this vulnerability is available from the following Microsoft page:

This worm also exploits the IIS5/WEBDAV buffer overrun exploit affecting Windows NT platforms, which enables arbitrary codes to execute on the server.

The following link offers more information from Microsoft about this vulnerability:

When it finds a vulnerable target machine, it copies and executes itself on the system.

It also searches for the following network shares:

If these folders have full access rights, it attempts to copy itself to these network shares. However, if these shared folders have restricted access rights, the worm attempts force its way into the system by logging in using the following user names and passwords:

Backdoor Capabilities

The malware has backdoor capabilities, such as stealing CD Keys and sending them to the malicious user. It engages in port scanning activities in order to connect to the malware author. It also uses Secure Socket Layer (SSL) so that it can encrypt the packets that it sends to avoid detection.

This malware acts as an IRC (Internet Relay Chat) bot, and is capable of performing the following routines on a target system:

Information Theft

This worm attempts to steal CD keys of the following applications:

The following data regarding the compromised system is also sent by the IRC bot to a remote malicious user:

  • CPU
  • RAM
  • OS
  • System Uptime Details

  3. In the right panel, locate and delete either of the following entries:
    x~{{dybel = "x~{{dy8%nsn"
  4. In the left panel, double-click the following:
    HKEY_LOCAL_MACHINE>Software>Microsoft>
    Windows>CurrentVersion>Runservices
  5. In the right panel, locate and delete either of the following entries:
    x~{{dybel = "x~{{dy8%nsn"
  6. Close Registry Editor.
NOTE: If you were not able to terminate the malware process from memory as described in the previous procedure, restart your system.
