Suspected North Korean hackers recently targeted several South Korean think tanks and security-related institutions. Their primary target appeared to be the Korea Atomic Energy Research Institute (KAERI), South Korea’s sole nuclear power research institute. In response to the recent attacks, the U.S Department of State called for strengthening the international joint efforts against North Korean cyber threats.
According to South Korea’s National Intelligence Service (NIS), KAERI had likely been exposed to cyber attacks by North Korea for 12 consecutive days, local media reported. The attacks appeared to have been carried out by North Korean state-linked organizations. Fortunately, they are not believed to have resulted in leakage of KAERI’s core research.
