Limbo 2, a new custom-built trojan designed to continually evade the top ten security software products on the market, is causing havoc on the net.
Discovered by software company Prevx, the trojan features a highly changeable shell with unlimited variants, so it can be customised by hackers to ensure the Trojan remains undetected by major anti-virus software. Personalised versions of the malware are fetching up to £700 each on illegal forums.
The Trojan steals financial information and hijacks live banking sessions, not only keylogging but also adding spoofed information boxes asking for users to enter more information than usual. This information is then filtered back to the owner of the malware.
Jacques Erasmus, director of Malware Research at Prevx said: "This is one of the most dangerous Trojans out there at the moment. The strength of this piece of Malware lies in its versatility, even if it is recognised up by an anti-virus company it can be changed so as to be invisible again within hours. There are likely to be so many variants out there that they will never all be detected, which is a scary thought as it is designed to steal bank details".
