When Sony Pictures employees got into the office on November 24, they discovered that their corporate network had been hacked. The attackers took terabytes of private data, deleted the original copies from Sony computers, and left messages threatening to release the information if Sony didn’t comply with the attackers’ demands.

Sony’s network was down for days as administrators struggled to repair the damage. Staff were reportedly forced to work on whiteboards to do their jobs.

But the greater damage was from all the confidential information that got leaked to the public. The hackers posted five Sony movies (four unreleased) to file-sharing networks. And they also leaked thousands of confidential documents — everything from private correspondence among Sony executives to salary and performance data about Sony employees. Those documents were password protected, and whoever is behind the hack provided said password only to journalists. But it’s likely only a matter of time before they break out into the world at large.
