"China-based hackers stole plans for Israel's Iron Dome missile defense system in 2011 and 2012, according to an investigation by a Maryland-based cyber security firm first reported by independent journalist Brian Krebs.
The hackers also stole plans related to other missile interceptors, including the Arrow 3, which was designed by Boeing and other U.S.-based companies.
"According to Columbia, Md.-based threat intelligence firm Cyber Engineering Services Inc. (CyberESI), between Oct. 10, 2011 and August 13, 2012, attackers thought to be operating out of China hacked into the corporate networks of three top Israeli defense technology companies, including Elisra Group, Israel Aerospace Industries, and Rafael Advanced Defense Systems.
First one should note that the Iron Dome has changed much since that data and that it is only effective because it has been totally adapted to the specific characteristics of the rockets that are used against it
seondly it is clear that this is economic espionage because China is nowhere to be seen in the market of the anti-missile market and so it is normal that these hacks on command happened
thirdly it is just another proof - if you ever needed one - that the security of even the highest classified data and networks is not as stringent as it should be even in a country where there are a lot more official rules and punishments in the field of cybersecurity because they are permanently under attack and the existence of their state itself depends on it
