Investigations by Elliptic and TRM Labs point to North Korean hackers, possibly UNC4736 (also known as AppleJeus and Labyrinth Chollima), a threat actor previously linked to Lazarus. The attackers cultivated a presence within the Drift ecosystem over six months, posing as a quantitative firm. They approached Drift contributors in person at multiple crypto conferences, building trust and rapport. Communications continued via Telegram, where they discussed trading strategies and potential vault integrations, demonstrating technical proficiency and familiarity with Drift\u0026rsquo;s operations.
