Under Active Attack

Executive Summary

In December 2025, the Cybersecurity and Infrastructure Security Agency (CISA) released five separate advisories detailing multiple vulnerabilities discovered across widely deployed industrial control systems (ICS) products, including platforms from Industrial Video & Control, Iskra, Mirion Medical, and Mitsubishi Electric. These vulnerabilities range from improper authentication and unencrypted data flows to weak access controls and, if left unmitigated, could enable threat actors to compromise critical infrastructure, hijack remote operations, or disrupt medical and industrial processes. The affected organizations were notified, and remediation guidance was provided to reduce risk and limit exploitation by sophisticated actors.

This disclosure underscores an ongoing trend of vulnerability discoveries in ICS environments, where legacy protocols, insufficient segmentation, and growing connectivity increasingly expose operational networks to targeted attacks. Continued disclosures by agencies like CISA emphasize the urgent need for robust visibility, segmentation, and zero trust architectures in protecting critical infrastructure.

Why This Matters Now

Industrial control systems underpin critical sectors like energy, manufacturing, and healthcare—and newly discovered vulnerabilities allow attackers to target operational technology networks that once were considered isolated. With ransomware and nation-state threats sharply focused on ICS/OT, organizations must act quickly to address exposed gaps before they are exploited in the wild.

Frequently Asked Questions

Gaps included unencrypted data flows, insufficient authentication, and lack of proper segmentation—leaving critical systems at risk of lateral movement or remote compromise.

Cloud Native Security Fabric Mitigations and ControlsCNSF

Implementing CNSF controls such as zero trust segmentation, east-west traffic security, and egress policy enforcement would have hindered attacker movement, C2 communications, and exfiltration attempts. Enhanced visibility, anomaly detection, and in-line IPS could enable organizations to detect, prevent, and contain each stage of the attack sequence.

Initial Compromise

Control: Inline IPS (Suricata)

Mitigation: Real-time detection and prevention of exploit attempts.

Privilege Escalation

Control: Zero Trust Segmentation

Mitigation: Prevention of unauthorized lateral privilege escalation.

Lateral Movement

Control: East-West Traffic Security

Mitigation: Detection and blocking of unauthorized internal movements.

Command & Control

Control: Egress Security & Policy Enforcement

Mitigation: Disruption of outbound malicious communication.

Exfiltration

Control: Cloud Firewall (ACF)

Mitigation: Prevention of unauthorized data exfiltration.

Data Exposure

Potential exposure of sensitive operational data, including energy consumption metrics, water treatment parameters, medical dosage information, and manufacturing process details.

Recommended Actions

  • • Segregate ICS and operational zones with zero trust segmentation to prevent broad attacker movement.
  • • Deploy inline IPS and anomaly detection to rapidly block exploits and detect suspicious activity at all network layers.
  • • Enforce east-west and egress traffic controls to limit lateral movement and stop data exfiltration.
  • • Continuously monitor, baseline, and log all privileged access and policy changes across multi-cloud and on-prem environments.
  • • Regularly update and test incident response playbooks to ensure coverage for emerging ICS vulnerabilities and cloud-native attack vectors.
