[QUOTE="Winter Soldier, post: 629928, member: 59377"] There are some variants, for example the kill-switch call has been eliminated by modifying the hex of the executable and bypassing the concerned calls: probably these versions were not made by the original author, because by analyzing the code, it is clear that it was not done a compiler. Indeed, subsequently to the control of the kill switch, the flow of code execution proceeds to create a service called "mssecsvc2.0" (displayed with the symbolic name "Microsoft Security Center (2.0) Service"), starting it and pulling out the ransomware component and performing it.
