Brief Description 

    

IRCbot.BIJ is a backdoor that allows hackers to gain remote access to the affected computer in order to carry out actions that compromise user confidentiality and impede the tasks performed on the computer.

 

It captures certain information entered or saved by the user, with the corresponding threat to privacy: passwords saved by certain Windows services.

It sends the gathered information to a remote user by any available means: email, FTP, etc.

 

It reduces the security level of the computer: it terminates processes belonging to security tools, such as antivirus programs and firewalls, leaving the computer defenseless against attacks from other malware; it listens on open ports in order to control the computer remotely; it awaits remote-control orders received through IRC.

 

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

  • It terminates processes corresponding to several security tools, such as antivirus programs and firewalls, to prevent detection.
  • It deletes the original file from which it was run once it is installed on the computer.

 

IRCbot.BIJ 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.
  • IRC: It sends a copy of itself to all users connected to the channel to which the infected user is connected.
  • Computer networks (mapped drives): it creates copies of itself in mapped drives.
