The builder application for the SpyEye trojan has been cracked prompting fears that the number of infections will spike and botnets will be harder to trace back to their creators.
Along with ZeuS, SpyEye is one of the most sophisticated and popular trojans used by cyber fraudsters to steal online banking credentials and other financial information.
SpyEye appeared as an alternative to ZeuS, the absolute king of online banking trojans, but last year both crimeware toolkits ended up under the supervision of the same developer who planned to merge them together.
According to a recent report from security vendor Trusteer, ZeuS still remains the most widely used crimeware toolkit, particularly because the source code of ZeuS leaked earlier this year which allowed anyone to create new samples.
