1/10: Gaobot.CKP Worm Lets Hackers In
January 10, 2005

Gaobot.CKP is a worm with backdoor characteristics that allows hackers to gain remote control over the affected computer and carry out actions such as command execution, download and execute files, log keystrokes, obtain different information on the computer, launch distributed denial of service (DDoS) attacks, etc.

Gaobot.CKP uses different means to spread:

  • It makes copies of itself in the shared network resources it accesses to.
  • It exploits the LSASS, RPC DCOM and WebDAV vulnerabilities to spread across the Internet.
  • It can access computers with the applicaction SQL Server installed, and whose SA (System Administrator) account password is blank.
  • It takes advantage of the backdoors opened by the worms Bagle.A and Mydoom.A, in order to spread to those computers affected by these worms.
  • It uses the following backdoors in order to enter the affected computer: Optix, NetDevil, Kuang and SubSeven.
  • It affects computers with the program DameWare Mini Remote Control installed and running.

    If running a Windows 2003/XP/2000/NT computer, it is highly recommendable to download the security patches for the LSASS, RPC DCOM and WebDAV vulnerabilities from the Microsoft website.
