Greg Sinclair of Google Cloud Security’s FLARE team discusses reverse-engineering work behind identifying, naming, and attributing North Korean cyber activity associated with Lazarus Group. The episode emphasizes binary-similarity analysis as a method for grouping related malware families and strengthening attribution confidence across sophisticated campaigns. The excerpt does not provide a specific intrusion timeline, victim set, malware hash, or infrastructure list, but it is relevant for understanding how technical malware relationships support Lazarus tracking. Its value is methodological: it explains how reverse engineers use shared code traits and family relationships to connect activity that may otherwise appear fragmented.
