Yes, I can verify that. We used CryptoLocker to network the office computers at the TV station where I worked. There was a scandal and with help from a detective we were able to locate some extremely "questionable content" (like potentially illegal) on 2 of the users's machines. I really had to get in there to ask questions, because the tech responsible for security on those sytems swore they would not be vulnerable. It was a close call, by any means. You just can't always trust the information, no matter what the source these days. It is critical to go in and check for yourself if you want to have any peace of mind.
