As repordted by YONHAP News on Wednesday, Defense Minister Kim Kwan-jin told a parliamentary session that signals were detected originating from the North’s western border city of Kaesong and were also believed to be emitted from Mount Kumgang on the Korean Peninsula’s east coast.
“Besides Kaesong, Mount Kumgang is believed to be a site where the GPS jamming signals were originated,” a participant quoted Kim as saying at the closed-door session.
Seoul’s military officials have said the signals were sent from the North’s western border cities of Kaesong and Haeju, but it was the first time that Kim mentioned Mount Kumgang as a potential origin of the electronic attack.
Kim said the North’s attempt to block military communications was ineffective because most military devices use a military-only satellite navigation system.
“To cope with a future disruption of GPS signals, the ministry will step up a cooperation system among private, government and military sectors,” Kim said, according to the participant.
The North’s latest electronic attack may have been intended to disrupt the joint military exercises by South Korean and U.S. forces that run until Thursday, military officials here said.
North Korea has been thought to have been responsible for the intermittent failure of GPS receivers since last year. (*)
