Possible Cyber Attack Against South Korean Banks and TV Stations

B3ryllium writes "At least four broadcasters and two banks in South Korea are reporting massive computer accessibility issues, saying that their networks are 'paralyzed' by what looks like a cyber attack. Additional reports from Twitter suggest that hundreds of computers in the country powered off simultaneously at 2:20am, and reported "Boot device not found" errors. South Korea's military has upgraded its "Information Operation Condition (INFOCOM)" level from Level 4 to Level 3 in response to this situation."

According to additional reports throughout the day, malware was transmitted through patch management servers, affecting hundreds of PCs at the broadcasters and banks. The malware was designed to target the master boot records of the computers, taking them offline, and according to another article, local security experts say that this is an example of an advanced persistent threat.
