Though it doesn’t compare to the horrific 77 million compromised user accounts via Sony’s PlayStation Network in 2011, Gamigo’s 8 million leaked user email addresses and passwords is most likely 2012’s largest security breach. The German online game publisher discovered it had been hacked in late February and notified its customers. But five months later the identifying credentials of its users were posted as a text file to a site called SendSpace. Though most customers changed their Gamigo passwords when the company first notified them in February, when the old passwords became public it posed a much greater threat--what if they used those old passwords on other sites around the Internet? Those needed to be changed, too.
