While passwords are encrypted, OP Productions admits a brute force approach could get through as many users are "not using strong passwords." They advise changing them immediately.
No financial data was copied, they say. OP Productions issued a security alert via email to War Z users today informing them of the database intrusions.
No names or addresses were taken as OP doesn't record those and all financial transactions are handled by a third-party. Right now they urge those affected to begin changing to stronger passwords on their and other websites using similar aliases or email addresses as a precaution.
"This has been a humbling experience for us," OP Productions said. "While we all know that there is no guaranty of security on the internet, our goal is to try our very best to protect your data. We sincerely apologize."
The War Z gained notoriety not along ago for being sold on Steam despite the received product not matching many of its claimed features. At the time the developer behind the projectbut shortly apologised for not delivering what was promised, and revised the game description and feature list. Valve pulled the game.
