Experts from Cyphort Labs have discovered an extensive data theft campaign named Nighthunter that has been active since 2009 stealing victims credentials. The malicious campaign is cross sector, every industry has been targeted without distinction, the experts havent noticed any targeted attack in the criminal operation. The attackers used several different keyloggers ( e.g. Predator Pain, Limitless, and Spyrex) to steal the victims credentials and send them to a remote email server.”]
