Brief Description 

    

BeastDoor.GX 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: email addresses; user's browsing habits; screenshots of actions carried out.

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

 

It affects productivity, preventing tasks from being carried out:

  • In the affected computer: causes system slowdowns.
  • In the local network: it generates a large amount of network activity and consumes bandwidth; it carries out denial of service attacks against mail servers on the local network.
  • On remote sites: it mass mails junk mail (spam).

 

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 notifies the attacker that the computer has been compromised and is ready to be used maliciously; it awaits remote-control orders received through other channels.

 

BeastDoor.GX accesses several websites to download files, which it then runs. These can be any type of file, although they are normally malware.

 

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.

 

BeastDoor.GX does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc.
