Pro-North Korea website Uriminzokkiri.com has been hijacked by hackers who accuse Kim Jong Un of "threatening world peace."

Uriminzokkiri's main site was offline Thursday morning, while its Twitter feed, Flickr stream and a number of companion websites had their content replaced with anti-North Korea messages.

Notably the hackers posted a cartoon wanted poster of Kim Jong Un – "aka Nuke Nuke Mickey Lover" – with a list of his alleged crimes, including "threatening world peace with ICBMs and nuclear weapons," "wasting money while his people starve to death," and "concentration camps and the worst human rights violation in the world."

North Korea's supreme leader was drawn as a pig, with a huge tattoo of Mickey Mouse. Other images showed the Anonymous hacker collective's iconic Guy Fawkes mask covering the North Korean flag.

Meanwhile Uriminzokkiri's official Twitter account picture had been changed to show two mask-wearing dancers, alongside the legend "Tango Down" and links to hacked companion sites:

Hours before Uriminzokkiri was taken down, Anonymous-affiliated hackers had already claimed to have published the names, email addresses, passwords and dates of birth of more than 9,000 of the site's registered users.

The list was accompanied by a message warning the North Korean government that "We are inside your local intranets [...] we are inside your mail servers, we are inside your web servers."

Hackers have already proved that these are no empty threats. Under the banner of "Anonymous Korea," they claim to have waged a politically driven cyberwar on North Korean websites since Saturday under the hashtag #OpNorthKorea.

State-owned sites including the Korean Central News Agency and Air Koryo have been sporadically unavailable since Saturday, according to North Korea Tech.

Uriminzokkiri ("Our Nation" in Korean) is based in China, but publishes news and propaganda from North Korea's state media and is considered one of Pyongyang's primary online mouthpieces. Its YouTube channel, for example, was first to post the bizarre dream-sequence video of a North Korean rocket destroying a city that looked a lot like New York (since removed due to copyright claims).

Its Twitter account has been hijacked once before, in 2011, prompting Pyongyang to warn of "grave consequences" for those behind the attack.
