Rising SpyEye malicious code threat

AhnLab announced that its research has identified a significant majority of the domains and hosts for the SpyEye Banking Trojan are in the US. The malicious code has gained attention as of late for the threat it poses to online banking user information.

According to SpyEye-relevant host data extracted by the AhnLab Packet Center, 48% of all SpyEye domains were found to be located in the US, followed by Russia at 7%, and the Ukraine at 6%.

The AhnLab Packet Center is the company’s malicious packet analysis system, which assesses suspicious packet data, including that from SpyEye C&C servers. The findings indicate that the main targets of SpyEye are mainly in the US, and that North American financial institutions and users should remain especially vigilant.

Since its toolkit first became public in 2010, the SpyEye Trojan has produced many variants. According to analysis by the AhnLab Packet Center, the “10310” variant was identified as the most distributed version at 34.5%.

The “10299” and “10290” variants followed at 14.7% and 14.6%, respectively. Additional variants are expected in the future.

SpyEye, along with ZeuS, are notorious banking Trojans that have helped thieves steal more than $100 million around the world. Without an end-user PC solution, banks face great difficulty protecting individual customers from the sophisticated threats posed by these malicious codes.
