Brief Description 

    
Haxdoor.S is a Trojan with backdoor characteristics.
Haxdoor.S allows hackers to get into and attack the affected computer. Hackers can capture screenshots, steal personal data, etc.
Furthermore, due to its backdoor characteristics, Haxdoor.S allows hackers to gain remote access to the affected computer. Therefore, hackers will be able to carry out actions that compromise user confidentiality and impede the tasks car-ried out 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 reduces the security level of the computer: it opens one or more ports to allow remote access to the computer and takes action that compromises user confidentiality.

 

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

  • It uses techniques included in its code to hide itself while it is active.

 

Haxdoor.S 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.
