Recommendation

  • Inventory all internet-facing infrastructure and audit access logs for anomalous, non-standard connection patterns consistent with stealthy persistence.
  • Review network egress logs for spikes in traffic to unknown or suspicious external IP space that may indicate C2 heartbeat activity.
  • Prioritize the hardening of edge devices, particularly VPN and firewall gateways, as these are common entry points for Volt Typhoon activity.
