Talos described defensive coverage work tied to Novetta’s Operation Blockbuster research on Lazarus Group, also referred to as Group 77. The underlying research connected multiple malware families to the same threat actor group and associated them with high-profile attacks over a nine-year span. Talos examined malware samples provided through the collaboration to verify coverage across the families and directed defenders to the Operation Blockbuster report for IOCs and malware-operation details. The excerpt emphasizes Snort rules, ClamAV signatures, AMP, web scanning, network security, and email security controls as defensive layers against the malware and delivery activity used in these campaigns.
