Blackshades has been proven backdoored on many occasions. Read around the threads on HF and you'll see valid proof.

Yes, but there's a difference between the legit and cracked version. Can you find anywhere that says the legit version is backdoored?

They've admitted that it's backdoored, it's just the purpose that people are debating about.

What do you think the purpose is?

"A programmer may sometimes install a back door so that the program can be accessed for troubleshooting or other purposes. However, attackers often use back doors that they detect or install themselves, as part of an exploit."

I'd say probably as part of an exploit as they don't need access for troubleshooting.

I heard it was so that they could prevent scams with the in-client exchange. At least that's what they claimed.
