The source code of the SpyEye malware development kit is now available thanks to Xyliton and the Reverse Engineers Dream Crew. This is great news for the security research and anti-malware communities. But it also exposes the source code to other malware developers who can now adapt and morph SpyEye into a new, more insidious threat. The best way to develop effective defenses for SpyEye attacks is to understand the inner workings of the malware, and be able to identify unique aspects of SpyEye threats so they can be blocked.”]
