BBC’s Lazarus Heist episode “Big Boss” follows the hackers’ turn to the dark web and highlights a figure called “Big Boss” as important to the ATM heist. The available source is a short BBC Sounds listing, so it supports only the episode’s focus and not specific malware, wallet, server, or IOC claims. For DPRK-focused tracking, this is contextual reporting on alleged support infrastructure and criminal facilitation around the ATM cash-out story.
