McAfee ATR's Speakerdeck abstract frames Hidden Cobra, also known as Lazarus, as a North Korea-linked actor active since at least 2007. The talk focuses on 2018 research into campaigns using complex implants for intelligence collection, operational disruption and revenue generation through cryptocurrency and banking theft. It also promises detail on new implant frameworks, backend operations, law-enforcement collaboration and Operation Sharpshooter, which McAfee says expanded from an isolated incident into a long-running infrastructure investigation. The source is a conference-slide abstract, so it supports campaign and research scope rather than fresh indicators.
