South Korea blames DPRK for military intranet hack

South Korea on Tuesday accused Democratic People's Republic of Korea (DPRK) of hacking its military intranet and leaking confidential information.

The accusation was made in a news briefing by South Korea's Defense Ministry spokesman Moon Sang-gyun, reports the CNN.

"We've identified that malicious codes had spread to some computers in the intranet system," he said.

"The Ministry of National Defense assembled a joint investigation team, and after the investigation, we've confirmed that some military data, including confidential information, was leaked. North Korea is assumed to be behind this," he added.

However, the South Korean military still has not determined what exactly has been leaked, but said it was possible the hack could lead the command to rewrite military operation plans.

If the accusations are true, it wouldn't be DPRK's first breach of South Korea's cybersecurity this year.

In March, top South Korean government officials' smartphones were hacked by DPRK, according to the country's spy agency, stealing text messages and voice communications by "sending enticing text messages.
