[x] Block Moonstone Sleet a new North Korean threat actor.
Description
A new North Korean threat actor, now tracked as Moonstone Sleet (formerly Storm-1789), that uses both a combination of many tried-and-true techniques used by other North Korean threat actors and unique attack methodologies to target companies for its financial and cyberespionage objectives. Moonstone Sleet is observed to set up fake companies and job opportunities to engage with potential targets, employ trojanized versions of legitimate tools, create a fully functional malicious game, and deliver a new custom ransomware.
Moonstone Sleet uses tactics, techniques, and procedures (TTPs) also used by other North Korean threat actors over the last several years, highlighting the overlap among these groups. While Moonstone Sleet initially had overlaps with Diamond Sleet, the threat actor has since shifted to its own infrastructure and attacks, establishing itself as a distinct, well-resourced North Korean threat actor.
