    In recent weeks, a major Korean electric utility has been affected by destructive malware, which was designed to wipe the master boot records (MBRs) of affected systems. It is believed that this MBR wiper arrived at the target systems in part via a vulnerability in the Hangul Word Processor (HWP), a commonly used application in South Korea. A variety of social engineering lures were used to get would-be victims to open these files. Below is a quick overview of the attack ...
