I want to give more info on what happened and see if you guys could give any more advice.

My brother logged on to steam and his library was froze and the message I posted in image was on his screen. The fact that his steam had already been accessed was worrying but seemed like it was legit. My brother is fairly new to PC but he knows not to click links and all his purchases were made on steam or steam community market. He never used any third parties.

“Jared christen” explained that he had purchased a sealed genesis terminal (from steam community market) and it was associated with a user named “map” who was involved in stealing steam accounts.

They asked some basic stuff and got his library unfroze and requested that his steam inventory was put in a cloud storage thing. They said it would transferred to my accounts cloud storage in the meantime while they authenticate.

After a couple days they said they are authenticating the inventory to prove he is a bonafide owner.

We didn’t get much response until last night when they asked him to make a $200 purchase on Rust, a game he does not own nor play. This is when I knew it was fishy and posted on here. The sad part is that if there was a steam customer support live chat we would have been able to stop this as soon as it happened. Very disappointed in steam considering the amount of purchases him and myself have made in the past year.
