SEOUL, Aug 20 (Reuters) - Suspected North Korean hackers have targeted a joint U.S.-South Korea military exercise being held this week though classified information has not been compromised, South Korean police said on Sunday.
South Korean and U.S. forces will on Monday begin 11-day Ulchi Freedom Guardian summer exercises to improve their ability to respond to North Korea's evolving nuclear and missile threats.
North Korea objects to such exercises saying they are preparations by the U.S. and its South Korean ally for an invasion of it.
North Korea has previously denied any role in cyberattacks.
At that time, South Korea accused North Korea of being behind that cyberattack.
