A quick question.
Hello, so a few hours ago my friend was invited to a altpug match by randoms, he accepted them and was called on Skype, once they called him they spoke to him for a bit but just hung up after a short period of time, then just like that they had a RAT on his system although he had never downloaded anything, then they rebooted his PC, he turned it back on and all his items had vanished, but only expensive ones such as his butterfly knife, he has checked his market history and they were not sold (after writing this we check his trade history which had the proof they traded his stuff away), anyway, for the question.
A) How did they infect him? he never ran anything they told him to, never even went on any sites as he didn't trust them.
As I was writing this we uncovered all the other questions i had, like how they got his stuff off of his account.
So if anyone could help me out with that one that'd be great
Thanks in advance.
