Seoul: Suspected North Korean hackers have attempted an attack targeting a major joint military exercise between Seoul and Washington that starts on Monday, South Korean police said.
South Korea and the United States will kick off the annual Ulchi Freedom Shield drills on Monday through August 31 to counter growing threats from the nuclear-armed North.
Pyongyang views such exercises as rehearsals for an invasion and has repeatedly warned it would take “overwhelming” action in response.
The hackers — believed to be linked to a North Korean group dubbed Kimsuky — carried out “continuous malicious email attacks” on South Korean contractors working at the allies’ combined exercise war simulation centre, the Gyeonggi Nambu Provincial Police Agency said in a statement on Sunday.
“Police investigation confirms that North Korean hacking group was responsible for the attack,” it said in a statement, adding that military-related information was not stolen.
A joint investigation by the police and the US military found that the IP address used in the latest attack matched one identified in a 2014 hack against South Korea’s nuclear reactor operator blamed on the group, according to the statement.
