Interesting, potentially two hacks have taken place in as many days. I'm assuming in your case
@Manzaitest it was due to either a RAT infection or you were the victim of a password stealer?
Sadly neither an outbound firewall or AV will protect you from having your passwords sent out to a remote server, the only way to prevent this is not to store your passwords on your PC (never use the "Remember My Password" feature of your browser, use something like LastPass instead). It is possible to mitigate against this kind of attack by setting directory permissions so as only your web browser is able to access your browser profile folders, whilst this technique can be effective it is essentially just bolstering the castle walls whilst leaving the main gate wide open
If anybody else is worried about their personal configurations in light of recent events, drop me a PM and I'll happily advise
