There are a few avenues for how North Korea might have acquired Chinese UAV technology. One is through official channels of purchase or provision. However, a Hong Kong newspaper, the South China Morning Post, reported that China TranComm Technologies, the vendor for Taiyuan Navigation, has denied that they had ever sold any UAVs to North Korea. Another is through back channels or the black market. However, UAVs are supposed to be on the September 2013 list of dual use items that China banned from being exported to North Korea. The SKY-09's has a relatively small price of a few thousand dollars, making the gains quite small compared to the potential domestic and international difficulties that could be caused if such channels were exposed. Another avenue is through traditional espionage or even cyber espionage. Unit 110, the cyber arm in the Reconnaissance Bureau of the (North) Korean People's Army, has reportedly intercepted U.S.-South Korean war plans in 2009, so acquiring foreign civilian UAV design information is within its capability. Yet this channel would risk antagonizing North Korea’s neighbor and only ally.
