Brief Description 

    

Lineage.AYF 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: passwords saved by certain Windows services; keystrokes, in order to obtain information for accessing online banking services, passwords and other confidential information.

 

  • In the local network: it generates a large amount of network activity and consumes bandwidth.

 

It reduces the security level of the computer: it notifies the attacker that the computer has been compromised and is ready to be used maliciously.

 

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.

 

Lineage.AYF 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.
  • It is dropped or downloaded to the computer by other malware specimens, for example: Multidropper.BOO.
