Amazon: Russian GRU Group Targets Western Infrastructure
🔐 Amazon Threat Intelligence details a multi-year, state-sponsored Russian campaign—assessed as GRU-linked—that targeted Western critical infrastructure, especially the energy sector, from 2021 through 2025. The actor shifted from exploiting N-day/zero-day flaws to abusing misconfigured customer network edge devices (including EC2-hosted appliances) to intercept credentials and gain persistent access. Amazon observed packet-capture based credential harvesting and subsequent credential replay attempts, with infrastructure overlaps linked to clusters tracked as Curly COMrades and Sandworm. Recommended mitigations include auditing edge devices, enforcing strong authentication, monitoring for credential replay, and applying AWS-specific controls.
