Brief Description 

    

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

 

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

 

Spammer.ALU 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.

 

Spammer.ALU 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.
  • Email: sending emails that include a copy of itself as an attachment. The computer is infected when the attachment is run.
