Do the following to secure your account:

1. Scan for malware https://www.malwarebytes.com/
2. Check that the email and phone number on the Steam account are still yours.
3. Deauthorize all other devices https://steamhost.cn/twofactor/manage
4. Change passwords from a trusted/clean device.
5. Generate new backup codes for your Mobile App https://steamhost.cn/twofactor/manage
6. Revoke the API key https://steamhost.cn/steamcommunity_com/dev/apikey (there should be nothing in the APIKEY)


I assume when you say rank status, you mean prime?
If so you can restore it by the below steps:

https://steamhost.cn/help_steampowered_com/en/wizard/HelpWithGame
Enter name of the game in search bar,
Click on game,
Click on "it's not in my library",
"Restore removed package".


As for your items they are gone and will not be returned or refunded by Steam.

not just to see who is the one
