A remote administration tool (RAT) that bypasses the security features of a program, computer or network to give unauthorized access or control to its user.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
This backdoor program attempts to connect to a remote IRC server. It also attempts a Denial-of-Service (DoS) exploit on any machines it finds with an open Microsoft-ds (Directory Service) port.
During installation, the following files are created:
While active, the backdoor attempts to connect to a remote IRC server:
The backdoor also iterates the IP address and looks for available systems with an open Microsoft-ds port (specifically, tcp 445). If a vulnerable machine is discovered, the backdoor breaches the targeted machine's Windows Firewall, a form of Denial-of-Service (DoS) exploit similar to the notorious MS04-011 vulnerability.To protect the backdoor, the WMISRV Service is stopped when the debugger program Ollydbg is launched; this protective action makes the debugging process more difficult.
The backdoor edits the Windows Firewall Policy, to allow it to function as an authorized application.
It also sets two malware launch points as services:
The following mutex name is used by wmisvr.exe:
