Brief Description 

    

Spammer.ANI is a hacking tool. These are programs designed to enable malicious users to cause or facilitate action detrimental to the target computer.

However, under certain circumstances (for example with network administrators), they could be used to check the security status, possible attack channels (in order to minimize risks), etc.

These tools, even though they are not by nature viruses, are considered as dangerous to victims of attacks.

 

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

 

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.ANI 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.
  • Via Internet, exploiting remote vulnerabilities: attacking random IP addresses, in which it tries to insert a copy of itself by exploiting one or more vulnerabilities.
  • Email: sending emails that include a copy of itself as an attachment. The computer is infected when the attachment is run.
  • Peer-to-peer (P2P) file sharing programs: it makes copies of itself with enticing names in shared folders belonging to these programs. Other users of this type of networks then voluntarily download and run the infected files.
