Brief Description 

    

Gaobot.DAC 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.DAC 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 IIS5SSL vulnerabilities to spread across the Internet.

 

It is highly recommendable to download the security patches for the LSASS, RPC DCOM and IIS5SSL vulnerabilities from the Microsoft website.

Visible Symptoms 

    

Gaobot.DAC is difficult to recognize, as it does not display any messages or warnings that indicate it has reached the computer.
