In this July 3, 2013 photo, Chris Palm, director of corporate communications, runs a demonstration of global computer virus activity inside the war room at the McAfee headquarters in Santa Clara, Calif. The hackers who knocked out tens of thousands of South Korean computers simultaneously this year are out to do far more than erase hard drives, cybersecurity firms say: They also are trying to steal South Korean and U.S. military secrets with a malicious set of codes they’ve been sending through the Internet for years. Researchers at the McAfee Labs said the malware was designed to find and upload information referring to U.S. forces in South Korea, joint exercises or even the word “secret.” (AP Photo/Marcio Jose Sanchez)
