Microsoft researchers have identified Moonstone Sleet, a North Korean threat group, carrying out espionage and financial cyberattacks using a variety of techniques against aerospace, education, and software organizations. Moonstone Sleet’s multifaceted strategies blend cybercriminal and nation-state actor methodologies, including creating fake companies and distributing custom ransomware and a fake video game. Defenders are urged to adopt a multi-layered security posture to detect and respond to these activities.
Key takeaways from the meeting notes:
– Researchers at Microsoft have identified a North Korean threat group, Moonstone Sleet, engaging in espionage and financial cyber-attacks using a variety of techniques against aerospace, education, and software organizations and developers.
– Moonstone Sleet initially heavily overlapped with the known DPRK advanced persistent threat (APT) Diamond Sleet, but has since differentiated itself, moving to its own infrastructure and establishing a unique identity.
– The group engages in both espionage and financial theft, using a range of tactics such as fake job offers, custom ransomware, and a fully functional fake video game called “DeTankWar.”
– Moonstone Sleet utilizes trusted platforms like LinkedIn and Telegram to target victims, often masquerading as legitimate companies to engage with victims.
– Its whack-a-mole cyber defense strategy includes spreading malicious packages on professional networking platforms, creating its own ransomware called FakePenny, and using a multi-layered approach to infiltrate organizations.
– Defenders are advised to adopt a multi-layered security posture, involving endpoint protection, network monitoring, threat hunting, and a combination of technical defenses and strategic intelligence to mitigate the threat posed by Moonstone Sleet.
These takeaways provide a clear overview of Moonstone Sleet’s activities and the recommended defenses against their multifaceted cyber threats.
