Brief Description 

    

Agent.CTG is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions.

 

It uses stealth techniques to avoid being detected by the user:

  • It deletes the original file from which it was run once it is installed on the computer.

 

It uses several methods in order to avoid detection by antivirus companies:

  • It terminates its own execution if it detects that it is being executed in a virtual machine environment, such as VMWare or VirtualPC.
  • It terminates its own execution if it detects that a memory dump program is running, such as Procdump.
  • Its code is encrypted and it is only decrypted when it is going to run. Because of this, its code is not legible through a memory dump.
  • It terminates its own execution if it detects that a debugging program is active.

 

Agent.CTG uses the following propagation or distribution methods:

  • Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.
  • Via Internet, exploiting remote vulnerabilities: attacking random IP addresses, in which it tries to insert a copy of itself by exploiting one or more vulnerabilities.
