Korea Beat reports that Seoul’s finest have arrested three, ahem, unification activists on charges of distributing North Korean revolutionary literature on orders from North Korean agents.

This news, naturally enough, might get you wondering. Are there North Korean spies in my neighborhood or office? Is my mother-in-law a North Korean agent? How would I know?

Well, your Uncle Marmot — and the National Intelligence Service (NIS) — is here to help.

You see, the NIS has been marking the upcoming 59th anniversary of the start of the Korean War with an online event that includes a Flash game where you, the resident of Korea, can learn how to identify the spy or leftist criminal.

In case you need help, the NIS game describes the following individuals as possible spies/leftist criminals:

  1. Someone who sits in an odd corner at a PC room or elsewhere, uses the Internet to post and spread inpure content, and then leaves in a hurry;
  2. People who spread false rumors at anti-American or anti-government rallies and encourage violent demonstrations;
  3. Someone who uses Kim Il-sung or Kim Jong-il as a game avatar while praising them;
  4. Someone photographing military or industrial facilities or smelling out security;
  5. People calling for unification using inter-Korean economic cooperation or family reunions as pretexts.

Needless to say, the Kyunghyang Shinmun is not amused.
