Amazon Disrupts GRU Hackers Targeting Edge Devices
🔒 Amazon Threat Intelligence disrupted active operations attributed to GRU-linked hackers who targeted customer cloud infrastructure by abusing misconfigured edge devices. The multi-year campaign, observed since 2021 and focused on Western critical infrastructure and the energy sector, shifted in 2025 from zero-day exploitation to targeting exposed management interfaces on routers, VPN gateways, and network management appliances. Amazon isolated compromised EC2 instances, shared indicators, and advised audits, credential monitoring, and AWS controls like isolating management interfaces, restricting security groups, and enabling CloudTrail, GuardDuty, and VPC Flow Logs.
