Hi, my steam account turns out to have authorized a login from another country, As I remembered I have done nothing to compromise this account. I even used the Mobile Authenticator app. I didn't lose access to my account, as I can still login, but soon I realize that my steam wallet is depleted and I "supposedly" had gifted a game to another unknown account, which I did not realize and did not do. I have checked my sign in history and realizes that this hacker has compromised my account since last month, and there has been no emails or whatsoever. I have changed my steam password, and has reported for a refund for this unknown purchase, also reported that account for theft. What do I do next?
