I have not read the whole article because I’m to lazy but here is a picture from the article you posted. Antimalware is not perfect and cannot detect every threat on your PC. There have been cases of game developer accounts being hacked and then updates being pushed through those hacked accounts including stealer malware / spyware which would then be installed on your PC, which is not a Steam Database breach but a Steam Developer Account Hack. Maybe Steam should have stopped those updates IDK I’m no malware expert. EDIT: Btw. the last Steam Database breach I could find in my 2 mins of searching the web was in 2015.
