It's a correct usage. Both forms work, but I prefer the negative one.
I don't see how it can be called a win-win situation- in a win-win situation both parties benefit, and I fail to see how not knowing that someone has invaded a machine to steal personal information is of any benefit to the victim. That's like claiming that if a thief puts a mask on and robs you, you benefit from not knowing the identity of the criminal.
Please restrict your discussions to legal activities- discussions on how to break the law are not acceptable.
