QQPass.AGU 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: 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 uses stealth techniques to avoid being detected by the user:

• It uses techniques included in its code to hide itself while it is active.
• It injects itself in running processes.

QQPass.AGU 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.
• Computer networks (mapped drives): it creates copies of itself in mapped drives.
