Anyway... The Decrypt Service is the server, the webpage that will provide you with the program you need to decrypt your files back to their original form (after payment). This server is hidden behind Onion.to, which means it's horrendously difficult to trace. Maybe their server is in Russia, China or even your at your neighbor's. One can't really tell because Onion.to creates a chain of randomly chosen computers as a path to the final server. This chain-route can go from Miami to Russia, then to Australia, then back to Miami and then finally to the crook's server.
The Onion.to address they use (at least one of them) is: https://rj2bocejarqnpuhm.onion.to/*** where three dumb alphanumeric characters are used to identify the victims. When you visit that link, this is what you see:
So, you fill the blanks with the code in the image (CAPTCHA) and proceed to the REPAIR.. oh, sorry DECRYPT SERVICE... Thanks God!
So, what if you don't really believe in this site? What if that page content is FAKE and not about your computer? Oh, well there you have "My Screen" section, in which you can see YOUR ACTUAL COMPUTER SCREEN!
Isn't that enough? Well, then there you have the Test Decrypt section where you can upload just one small file (only once) and get it decrypted in order to check the "service" works.
The crooks...under the name of Victor Yanukovich also uploaded a video to YouTube that clearly shows you this shit is 100% REAL.
He is also gentle enough to show you step by step how to pay for his "SERVICE".
