Antivirus Software Incapable to Find Top Three Trojans

The IT Security Firm Trusteer states that antivirus program is completely incapable at detecting the dominant three Trojans- Yaludle, Silon and Zeus, which were responsible for stealing from UK financial institutions.

Out of 42 antivirus engines tested, only 14 were able to discover the Zeus Trojan, as per the firm's research. Further, Silon, the second most active Trojan, was found only by Trend Micro's antivirus engine and Panda Software and F-Secure could detect the third most rampant Trojan, Yaludle.

Further, Trusteer also disclosed that almost 90% of bank fraud held these three malware groups responsible for the trojans attacks. 1 out of 100 systems were hit with Zeus Trojan and it end up being the most abundant one. The Zeus Trojan is often used to jeopardize individual banking accounts in the UK.

CEO of Trusteer, Mickey Boodaei, claimed that most of the hackers use Zeus, but there is not clear association between Yaludle and Silon, as per the news published by SCMagazine on March 17, 2010.

Boodaei said that this is something useful for an original crime group for developing themselves and it will not be seen anywhere else. For instance, Zeus is platform specific, and it can be used in other countries as well in the time to come.

Explaining the detections and the number of infections, Boodaei opined that he did not have precise details because every piece of malware is not similar.

Along the lines of Boodaei's claim, information from another security firm, Prevx, demonstrated that it first observed attacks on 4th September 2009, and until March 16th 2010, the firm had seen 97 agents with 50 unique executables. Out of those variants, the maximum was 17 findings of just one file name. Resembling Boodaei's comments about the uniqueness of it, most of the filenames had just one agent seen.

As a solution to this problem, Boodaei recommends that banking institutions and their customers should be clearer about what malware can be used for online theft so that they can exactly know which of the several kinds of malware they should be protected against most, as per the news published by ComputerWeekly.com on March 17, 2010.
