Defensive Guidance
Summary

Show ▼
Organizations facing Iranian wiper campaigns are being urged to adopt a five-step containment playbook that cuts blast radius and limits destructive spread after initial access. The guidance emphasizes identity-aware access, default-deny administrative ports, tighter privileged access, tunnel detection for tools like NetBird, and automated isolation of compromised hosts. It matters because these operations are designed for disruption, not extortion, and can cripple critical supply chains, healthcare ecosystems, and infrastructure.

Five-step containment playbook for Iranian wiper campaigns
Initial DisclosureIran-linked destructive campaigns are described as relying on manual operations after initial access, including stolen VPN credentials, legitimate administrative tools such as RDP, PowerShell remoting, WMI, SMB, and SSH, and covert tunnels like NetBird. The guidance recommends identity-aware access controls, MFA for administrative services, default-deny administrative ports, privileged-access segmentation, east-west monitoring, tunnel detection, and automated isolation so wiper activity cannot spread across the environment.
