Security firm FireEye has observed cyber attacks aimed to hack the Terminal High Altitude Area Defense (THAAD) missile system. The THAAD system was designed by South Korea to protect the country from the incoming intercontinental ballistic missile (ICBMs), it is part of the Star Wars defense system. China has long been in opposition to the deployment of the THaAD since South Korea announced it as a key component of its defense infrastructure. The first components of the system arrived in South Korea last month and have been a key issue in the current presidential campaign.”]
