I got a leaked program of government in tor. It's making you able to search every data of a citizen in my country, its golden. I downloaded the software and datas as torrent. I checked datas if it's virus or real, I'm sure about it is not. I opened it in sandbox and it tried to connect to national police network but failed because of sandbox block. If I wouldn't use sandbox I'd probably got fucked up.
By the way the question is how to open that file in a virtual/safe computer, etc. The worst thing comes to my mind is an internet cafe. I'll wear a surgery mask then enter old man's internet cafe and use the program. What do you think? What is the safest way?
