There were (or are?) some older call of duty games being sold on steam that had unpatched RCE vulnerabilities in them. Simply joining a server ran by a malicious host can result in the players system being totally compromised. These games would go on sale once a year or whatever and attract new players, and people would post warnings in the steam forums and whatnot to try to stop people from being effected by the issue, but I am sure some people either didn't listen or didn't notice the warnings. I haven't looked into the issue in a few years at this point, but it's very possible that the games are still unpatched and being listed in the store to this day. Anything that connects to the internet needs to be strongly concerned about security!
