Brief Description 

    

Banker.DOF 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.

It sends the gathered information to a remote user by any available means: email, FTP, etc.

 

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 awaits remote-control orders received through FTP.

 

Banker.DOF 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.

 

Visible Symptoms

 

Banker.DOF is easy to recognize, as it shows the following symptoms:

  • It displays false error messages when it is run.
