Ok, Ok.
The .RAR file probably has nothing in it. Let me guess, the reason you want to hack into it is because the .RAR asks you to do a dam s u r v e y to get the "password" to use it. Oh, and it is from youtube, yes? Youtube is 100% viruses or scams.
The answer to the question of whether or not, you can create an aimbot for use in vehicles, is yes. I have seen them, and helped to build them. The reason why none of them work in these times, is because of the recent patch data. DICE changed the hexadecimal addresses within the game. This means that the aimbots don't aim at anything.
