Description: 

This worm propagates via network shares. It drops copies of itself on default network shared folders. It also uses its own list of user names and passwords to access password-protected shares. It takes advantage of the following Windows vulnerabilities to propagate across networks:

  • Buffer Overflow in SQL Server 2000
  • IIS/WEBDAV vulnerability
  • RPC/DCOM vulnerability
  • Windows LSASS vulnerability

For more information on these vulnerabilities please check Microsoft's Security Bulletins Web site:

This worm connects to an IRC (Internet Relay Chat) server. Once connected, it enables a remote user to issue certain commands locally of the affected machine.

It is capable of process termination. It terminates running processes related to antivirus and security applications. In addition, it also terminates the processes of previously hot malware like WORM_MYDOOM, WORM_BAGLE, WORM_NETSKY, WORM_MSBLAST, and WORM_SOBIG.

Moreover, this worm is an information thief. It steals the Windows product ID and the CD keys of several popular games if they are installed in the affected system.

Details:

Installation and Autostart Technique

Upon execution, this worm drops a copy of itself in the Windows system folder as LXES.EXE. It then creates the following registry entries to ensure its execution every system startup:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\
CurrentVersion\RunServices
Microsoftz turn Control = "aexl.exe"

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\
CurrentVersion\Run
Microsoftz turn Control = "aexl.exe"

It also adds the following registry entry as part of its installation routine:

HKEY_CURRENT_USER\Software\Microsoft\OLE
Microsoftz turn Control = aexl.exe

This worm modifies the following registry entries:

HKEY_LOCAL_MACHINE\Software\Microsoft\Ole
From
EnableDCOM = "Y"
To
EnableDCOM = "N"

HKEY_LOCAL_MACHINE\System\CurrentControlSet\
Control\Lsa
From
restrictanonymous = "dword:00000000"
To
restrictanonymous = "dword:00000001"

Network Propagation and Exploits

This worm propagates via network shares. It drops copies of itself on the following default network shared folders:

  • ADMIN$\system32
  • C$\Windows\system32
  • C$\WINNT\system32
  • IPC$

It also uses the following hardcoded list of user names and passwords to access password-protected shares:

Backdoor Routine

This worm connects to an IRC (Internet Relay Chat) server. Once connected, it enables a remote user to issue the following commands locally of the affected machine:

  • Add/Delete/List network shares
  • Capture screenshot using webcam
  • Create/List/Delete user accounts
  • Download/Search for files
  • Enable/Disable DCOM and anonymous login
  • Execute/List/Terminate processes
  • Flush DNS cache
  • Get system and network information
  • Get Windows login password
  • Launch DoS (denial of service) flood attacks using the ICMP, Ping, SYN, UDP methods
  • List/Start/Stop services
