The source code for the Spyeye toolkit has been leaked onto the Internet meaning that it could now be modified to create variants and prompt further malware infections and security attacks.

According to the network security company Damballa, the Spyeye toolkit, which includes the Zeus malware builder, was leaked by an infamous French security researcher named Xyliton, who is part of the Reverse Engineers Dream Crew (RED Crew).

The positive aspects of the leaked toolkit is that now security researchers are able to analyse the coding techniques of Gribo-Demon’s team (the authors of SpyEye) and begin bug hunting for vulnerabilities in the authors work.
