Executive Summary

Recent research presented by Censys and GreyNoise at LABSCon 2024 highlights significant security risks associated with internet-exposed Industrial Control Systems (ICS). The findings challenge existing assumptions, revealing that attackers frequently prioritize exploiting common Remote Access Service (RAS) protocols rather than targeting ICS-specific communication channels. This shift indicates that internet-connected Human-Machine Interfaces (HMIs) are being rapidly targeted by adversaries seeking initial access to critical infrastructure environments. The exposure of these systems poses a substantial risk to operational technology integrity and availability. Organizations managing critical infrastructure are urged to reassess their security postures, specifically focusing on reducing internet exposure for HMIs and securing RAS protocols. Implementing strict network segmentation and monitoring for unauthorized remote access attempts are crucial mitigation steps to prevent potential compromise and ensure the resilience of industrial operations against evolving threat landscapes targeting exposed assets.

Summary

Discover the latest findings from Censys and GreyNoise on the real-world threats facing internet-exposed Industrial Control Systems (ICS). At LABSCon 2024, they revealed surprising research on how attackers prioritize common Remote Access Service (RAS) protocols over ICS-specific communication, highlighting key security challenges for critical infrastructure. Learn more about how internet-connected HMIs are rapidly targeted and the implications for ICS security.
