Forescout Discovers Exposed RDP and VNC Servers Linked to ICS/OT Environments

Forescout identified tens of thousands of exposed Remote Desktop Protocol (RDP) and Virtual Network Computing (VNC) servers accessible via the internet, with some linked to Industrial Control Systems (ICS) and Operational Technology (OT) environments. The discovery highlights misconfigured or unsecured remote access services that could allow unauthorized entry into critical infrastructure. No specific industries, technical vulnerabilities (e.g., CVE IDs), or exact numbers of affected ICS/OT systems were disclosed in the report. The findings emphasize the risks of internet-facing remote access tools in sensitive operational networks. The exposure increases potential attack surfaces for threat actors targeting industrial sectors.
