i was trading skins on cs.money, but when i hit confirm trade in the mobile authenticator the trade didnt go through and cs.money stated "The trade has been cancelled in Steam. You are being scammed, unless you cancel it intentionally, Your Steam account is vulnerable, your items are at risk of theft. Please follow the next steps to prevent the damage"

and listed
"1. Change your password in Steam account settings
2. Revoke the API Key issued by scammers.
3. Create new trade URL
4. Please be careful when a third-party site asks for your Steam credentials (login, password) as it is the most prominent form of hacking into accounts."
Go to http://gtm.you1.cn/storesteam/twofactor/manage and deauthorize all devices from logging in to your Steam account. This is a further precaution against anyone logging in without your knowledge. Go to Steam API Key page and click “Revoke My Steam Web API key
