According to the report, one case involved a hacker who reset a South Korean psychologist's Android-based smartphone and used a stolen KakaoTalk account to spread malware disguised as a "stress relief program" to the victim's contacts in early September.
Another similar attack targeted a North Korean human rights activist, affecting dozens of the activist's contacts on Sept. 15. The attackers tricked them into installing malicious software by posing as trusted acquaintances.
They also infiltrated devices, used Google location services to track when victims were away from home or work, and then remotely reset the devices.
"The use of various tactics to delete data and carry out other attacks appears unprecedented," the report said, highlighting North Korea's increasingly sophisticated cyberattacks.
