A Twitter and Flickr account associated with a North Korean news agency has been taken over by hackers claiming to be from the hacktivist collective Anonymous. Instead of pro-North Korea propaganda, the accounts are now criticizing North Korea and its leader Kim Jong-un for building nuclear weapons. The hackers controlling the Twitter account also claimed to have hacked the news agency's website and other North Korean websites, which appear to be offline.

The Twitter and Flickr accounts represent Uriminzokkiri (meaning "Our Nation"), a North Korean news and propaganda site. When Uriminzokkiri established a Twitter account in 2010, the IDG News Service described the news site as "the closest thing North Korea has to an official home page" and "one of the few Web sites believed to be run from the secretive nation."

The Twitter page, with 14,000 followers, switched from posting in Korean to English this morning. The profile picture was changed to an illustration of two dancers wearing Guy Fawkes masks. The hackers of the Flickr account are posting various pro-Anonymous and anti-North Korea pictures. One depicts Kim Jong-un with pig ears and a Mickey Mouse picture on his chest and says he is "threatening world peace with ICBMs and Nuclear weapons."

The Twitter and Flickr hacks come several days after hackers purportedly affiliated with Anonymous targeted Uriminzokkiri and claimed to have stolen 15,000 hashed passwords. A Washington Post article from this morning said Anonymous launched distributed denial of service attacks against several state-run North Korean websites, but that claims Anonymous hacked into North Korea's intranet appear unfounded.

Tensions have risen between North Korea and South Korea in recent days, with North Korea also making threats against the US. "US Defense Secretary Chuck Hagel said Wednesday that the North Korean threats to Guam, Hawaii, and the US mainland have to be taken seriously," CNN reported.

UPDATE: Uriminzokkiri seems to have taken back control of its Flickr page, but the Twitter account is still showing the Anonymous posts.
