QQRob.OS is a worm that spreads by copying itself, without infecting other files.

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 terminates processes belonging to security tools, such as antivirus programs and firewalls, leaving the computer defenseless against attacks from other malware; it changes system permissions, decreasing the security level.

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 uses several methods in order to avoid detection by antivirus companies:

• It terminates its own execution if it detects that a memory dump program is running, such as Procdump.

QQRob.OS 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.
• Computer networks (mapped drives): it creates copies of itself in mapped drives.
