Yes I am gonna change all passwords, I nornamally use Roboform for entering passwords which avoids typing passwords but I will still change everything to be sure I am secure again.
One thing I did think to myself was, if there was an authenticator on the accounts (I removed it last week while I was leveling mutliple teams to speed up logging in, FACEPALM) then most likely I would not know my maching was hacked until either the antivirus found it or some other accont got hacked, THAT is kinda scarey.
This must be costing blizzard a LOT fo money
