Energy arrives as Setup.exe in a RAR file attached to an email. When executed, Energy creates the file Energy.exe in the Windows system directory. It loads itself as a service named "EnErGy". Energy periodically lists the system's running processes and runs its code from them, infecting as many running processes as possible.

Energy hooks the MAPISendMail function in processes that import MAPI32.dll. The worm adds itself as Setup.exe to any RAR archive attached to an outgoing email.

The worm has no destructive routines and does little more than spread itself. It will only run on Windows NT-based systems. It has some similarities to Benny's Hiv virus.


Energy was completed on the 14th of November in 2000 in the Czech republic. It's creator, Benny submitted it in 29A magazine, where it appeared in the 5th issue. He says he came up with the name after some meditation and psychadelic experiences.
