Blizzard has released a statement revealing that there's been a "recent increase in unauthorized World of Warcraft account-logins". These are coming in via Blizzard's site and the WoW mobile armory app, leading Blizzard to temporarily suspend access to its auction house via the game's mobile app. Affected account holders are being contacted by Blizzard and reminded, hey, two-step authentication exists for a reason.
