Brief Description 

    

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

 

It captures certain information entered or saved by the user, with the corresponding threat to privacy: email addresses.

 

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.
  • On remote sites: it mass mails junk mail (spam).

 

It reduces the security level of the computer: it changes the security settings of Internet Explorer, decreasing its security level; it notifies the attacker that the computer has been compromised and is ready to be used maliciously.

 

Alanchum.DT 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 uses techniques included in its code to hide itself while it is active.

 

Alanchum.DT 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.
