Community Manager Bashiok said that the company is taking the claims "extremely seriously" and is investigating the rash of account compromises. "Despite the claims and theories being made, we have yet to find any situations in which a person's account was not compromised through traditional means of someone else logging into their account through the use of their password," he said. "While the authenticator isn't a 100% guarantee of account security, we have yet to investigate a compromise report in which an authenticator was attached beforehand."
Blizzard is assisting compromised customers by restoring stolen items and rolling back their accounts. The studio has a post up on its forums to help players protect their accounts and get assistance if theft occurs.
