South Korea's presidential office, Cheong Wa Dae, is on alert against a possible cyber attack by North Korea after receiving related intelligence reports, officials said Wednesday.
"The National Cyber Security Center (NCSC) obtained intelligence on a (possible) cyber attack from North Korea," Cheong Wa Dae spokeswoman Kim
Hee-jung told reporters. A relevant team at Cheong Wa Dae is on an emergency alert footing from Tuesday in cooperation with the NCSC, she added.
The possible attack seems to be associated with the North's threat of "holy war" to retaliate against the large-scale joint naval drills between
South Korea and the United States in the East Sea, which are scheduled to end later Wednesday, she added.
The Web sites of Cheong Wa Dae and several other key government offices were hit last year and in recent months by a series of distributed
denial-of-service (DDoS) attacks, a massive number of access attempts, believed to be from the communist regime.
