China hacked into the corporate networks of three top Israeli defense technology companies, including Elisra Group, Israel Aerospace Industries, and Rafael Advanced Defense Systems. Most of the information was intellectual property pertaining to Arrow III missiles, Unmanned Aerial Vehicles (UAVs), ballistic rockets, and other technical documents in the same fields of study.  Based on the infiltration Chinese hackers were looking for information related to Israel’s all-weather air defense system called Iron Dome.  Attacks bore all of the hallmarks of the “Comment Crew,” a prolific and state-sponsored hacking group associated with the Chinese People’s Liberation Army (PLA) and credited with stealing terabytes of data from defense contractors and U.S. corporations.
