Timeline of key events in the Sony Pictures Entertainment hack
December 18, 2014 - 2:56 PM
It's been four weeks since hackers calling themselves Guardians of Peace began their cyberterrorism campaign against Sony Pictures Entertainment. In that time thousands of executive emails and other documents have been posted online, employees and their families were threatened, and unreleased films were stolen and made available for illegal download. The hackers then escalated this week to threatening 9-11-like attacks against movie theatres scheduled to show the Sony film "The Interview." That fanned security fears nationwide and resulted in the four top U.S. theatre chains pulling the film from their screens, ultimately driving Sony to cancel the film's release.
