The international hactivist group "Anonymous" took control of five North Korean websites on Monday, to coincide with North Korea's national holiday celebrating the birth of founder Kim Il-sung.
Visitors to the "Uriminzokkiri.com" website and the others were greeted with images mocking leader third-generation leader Kim Jong-un.
The group took over the official Twitter account for Uriminzokkiri earlier this month and tweeted that more North Korean websites were in their hands.
This is the second time that Anonymous has hacked North Korean sites this month.
It leaked the information of thousands of website users in the first attack.
