Accounts are phished not hacked.

You gave away all your account details.

The account name, the password and the KEY to the door, the Steam Guard Mobile code giving them access to the account.

How? by either logging into a known scam site or item sell sites, fake steam log-in websites, or by tailored malware on your PC, the vote for my team scam, you have a pending ban scam on Discord, free knife click the link etc.

How does Steam (a program) know it is not you when all the account details are correct? It doesn't, therefore any action taken on your account is seen as you doing said actions.

The alternative is not plausible:

1) Someone would have to "GUESS" your account name from "millions of possible combinations".

2) Next they would have to "GUESS" your password from "millions of possible combinations" and then match it to your account name with "millions of possible combinations".

3) And finally they would have to "GUESS" the Steam Guard Mobile code "which changes every 30 seconds" to match both your account name and password to then have access your account.

Your account was phished / hijacked. Follow steps 1- 8 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)

7. Make sure your steam recovery email account is secure and still accessible.

8. Do a PW reset to recover any steam points spent in last 14 days.

Steam will NOT return lost funds or Items.

Because you were phished on your computer. They grabbed the session token from that 30 second 2fa code, along with your login info. that is the only way. with all 3 parts of the key, they could use that at any time to log in as you, since they had the 2fa session token code, steam thinks it is you.

The only way to get all 3 parts of the key is from your computer, you were phished.
