Military investigators raid cyber command in hacking probe

SEOUL, -- Military investigators have raided South Korea's cyber command as part of their investigation into the first hacking of the command's intranet that is being blamed on North Korea, military officials said Tuesday.

"The Defense Security Command is thoroughly looking into how the cyberattacks took place, what confidential information has been leaked and if there was any professional negligence," a military official told Yonhap News Agency.

He confirmed that military prosecutors were overseeing the raid while the Defense Security Command was collecting documents in a raid to the cyber command on Tuesday.

In September, the defense ministry recognized that a total of 3,200 computers, including 700 linked with the intranet, were contaminated with malware a month after the latest cyberattack took place.

The ministry found in October some military documents were hacked while refusing to provide details. The computer used by Defense Minister Han Min-koo also turned out to have been compromised.

Last week, the ministry said the IP addresses linked to the attack were traced to a location in China that has been used by North Korean hackers.

As one of the military's two integration servers was jointly linked to the internet and the intranet, it allowed the hackers to gain access to the intranet, it said.

The cyber command separated the affected server from the whole network to avoid the spread of viruses in October, two months after the initial hacking attempt was made in August.

It marked the first time that the data of South Korea's cyber command has been compromised. South Korea set up the command in January 2010 as part of its efforts to counter external hacking attempts on the country's military.

North Korea -- which has thousands of cyberwarfare personnel -- has a track record of waging cyberattacks on South Korea and the United States in recent years, though it has flatly denied any involvement.
