A customer database belonging to UK retailer GAME has been breached, as has one belonging to Australian website Catalyst-Gaming, MCV reports. A list of over 2000 customer usernames, email addresses, and hashed passwords has been released.
GAME denied that it's been hacked. "The published email addresses are not registered users of GAME.co.uk, and there has been no breach of our database security." That leaves catalyst-gaming as a potential source of email addresses. Regardless, if you've used either site recently, a password change wouldn't hurt.
