Korean users of dcinside.com attacked frequent cyberwarfare opponent Japan - specifically the users of 2ch.org, who had been posting inflammatory anti-Korea comments. The event coincided with one of the early displyas of Korean independence during Japanese occupation in 1919. Koreans started spamming 2ch, continuously reloading and then launching a more sophisticated DDoS, eventually closing the site for a big portion of the day. During one point that 2ch was up, it was defaced with images of Korean flags. Japanese attacks on dcinside had very little success as it had been heavily reinforced in preparation. When the 2ch members redirected their attack at the South Korean President's website, it was ignored and even encouraged (the President was unpopular and even born in Japan). Finally 2ch turned its sights on VANK, successfully taking down the Korean PR site for a short period. These events are notable for several reasons, but especially given their extensive coverage and documentation.
