The three, surnamed Kang, 17, Bae, 14, and Woo, 23, posted a YouTube video on March 21, 2014, stating, "To the Government of South Korea. We are watching you, and We Expect for the changes of the Korean Government. ... This is the LAST WARNING MESSAGE for Korean Government. In April 14th 2014, Expect Our Revolution and You CAN'T STOP US!!"
According to the police, the threat was a hoax.
While Kang and Bae had met via Anonymous' Facebook and Twitter pages and Kang claimed to be a member of Anonymous, none of the three appears to have any hacking skills. "Police became suspicious when Anonymous denied the attack plans," the Chosun Ilbo reports.
