According to researchers at FireEye the security company, the notorious RAT (Remote Access Trojan) namely Gh0st is spreading infection together with Backdoor.ADDNEW a novel kind of backdoor Trojan which seizes passwords stored in Firefox while carries out Distributed Denial-of-Service assaults.

Gh0st that's basically used for online spying, targets Windows computers while having phone-home abilities for certain C&C (command-and-control) server. As the malware controllers maneuver Gh0st-contamianted systems remotely, they plant more malware that include surveillance-featured programs especially keyloggers.
