North Korean hackers have gained access to officials' emails, including those working for the foreign, defense and unification ministers, as well as creating 27 phishing sites on free South Korean hosts, according to the news outlet.
Last month, South Korean police said that North Korean hackers have targeted computer systems belonging to 160 large South Korean companies, government agencies and non-government organizations, infecting some 140,000 computers with malware.
North Korea is also suspected of targeting South Korea’s military in two separate cyberattacks in 2014 and 2015, but no decisive evidence has been uncovered. South Korea believes that Pyongyang operates a 6,000-strong special hacker unit.
In March, South Korea's spy agency, the National Intelligence Service, reportedly said that North Korea had stolen information from dozens of Seoul top government officials' smartphones.
