Summary

North Korea has had IT workers embedded in DeFi protocols since DeFi Summer — and they’re pretty good devs. Nick Bax, blockchain investigator and SEAL 911 incident responder, joins us to break down how crypto crime has evolved from SIM swaps to nation-state social engineering. We unpack the Monero inflation bug, Arbitrum’s 9/12 multisig gold standard, how DPRK workers now use facilitators to rent real identities, and what it actually takes to break into onchain investigation.
