State-sponsored Chinese hackers tried to disrupt the operation of the controversial THAAD anti-missile system in South Korea, CNN reported, citing American cyber security experts.
The U.S. news network said the hacking had taken aim at an unidentified organization with connections to the THAAD system.
China has vehemently opposed the THAAD installation here, claiming the system's powerful radar can penetrate its territory and undermine its security.
"China uses cyber espionage pretty regularly when Chinese interests are at stake to better understand facts on the ground," John Hultquist, the director of cyber espionage analysis at FireEye, told CNN. "We have evidence that they targeted at least one party that has been associated with the missile placements."
A spokesperson for South Korea's Ministry of Foreign Affairs said there was an attempted cyber attack in April, but did not say whether its target was the THAAD system.
Early this week, U.S. Forces Korea (USFK) confirmed the anti-missile system is operational, about a week after the USFK began installing the system at a former golf course in the rural town of Seongju, North Gyeongsang Province.
