Backdoor:W32/Moudoor is a derivative of the notorious Gh0st Remote Access Tool (RAT) that is notable for being a favored tool of a cyberespionage group that has been working since 2010 and targeting industries such as financial services, government departments and education facilities around the world.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
The F-Secure Online Scanner can also be used to check machines for signs of compromise. This stand-alone tool does not require installation, allowing a user to quickly download and run it to scan suspect machines.
More information on the scanning and removal options available in your F-Secure product can be found in the Help Center.

The Moudoor backdoor is typically delivered to a target via a 'watering-hole' type of attack, in which a website known to be visited by staff of the targeted institution is compromised in order to deliver malware to its visitors.
Once the backdoor is delivered to and installed on a machine in the targeted network, it is able to perform a wide variety of actions related to covert monitoring and file system manipulation, including extracting information from the infected machine(s).
This detection is part of a Coordinated Malware Eradication initiative that focuses on detecting and disrupting specific malware families, with emphasis on the advanced persistent threats used by cyber espionage or hacking groups to target multiple organizations around the world. Together with coalition partners such as ThreatConnect, ThreatTrack Security, Volexity, Symantec, Tenable, Cisco, and iSIGHT, this effort is aimed at reducing the impact of these groups' actions and collectively improving security for our customers.
