You logged in either into a fake steam website, got phished by another link for example "vote for my team" or "free giftcard" used your login on a 3rd party gambling, trading, skin site etc. There are tons of different ways to get caught. The only other way would be some kind of malware catching your active session, but if no malware is found, the only other possible way for that to happen, is that you used your login somewhere you're not supposed to do. It is impossible to get hacked through Steam Guard, because the code changes every few seconds and the attacker would need to have access to your phone to guess it, so you gave it to him at some point.
