Forescout Technologies has identified persistent malware attacks on operational technology and industrial control systems, with over 20% targeting engineering workstations. Two Mitsubishi workstations were compromised by the Ramnit worm, and newly discovered malware Chaya_003 designed to disrupt Siemens engineering processes was also detected. Non-specific OT malware remains the most prevalent threat, but Forescout noted the ability of hacking groups to create OT-specific malware with the aid of AI, and recommended workstations should be hardened, networks segmented and monitoring for threats intensified.
