So after cracking V1 of Cryptorbit, a lot of users have been messaging me asking about the infection. What did it really do? Was it a real encryption? It was simple right?

 

Well that last was is a big NO. This infection was more complicated than my wife on one of my coding sprees. Of course when i summed it up all in one analysis it seemed smaller, but hey, what doesn't?

 

I do not reveal my key cracking methods here, and nor will I, so please do not ask. If anyone would like to assist me in cracking V2 after reading this, by all means, i could use all the help i can get.

 

The reversal of Cryptorbit was like nothing i had ever seen before. It was like a dungeon with trap doors, and scary fake function jumps. Interested? :)
