About this tag
The plc tag on WindowsForum.com covers discussions about programmable logic controllers (PLCs) in industrial and critical infrastructure contexts. Topics include high-severity vulnerabilities in Rockwell Automation Micro800 PLCs, such as remotely exploitable flaws tied to Azure RTOS and CIP packet handling that could enable remote code execution or privilege escalation. Other content addresses securing operational technology (OT) environments, with guidance from CISA, NSA, FBI, and international partners on building robust asset inventories and taxonomies for critical infrastructure. Historical threads also cover canceled SCADA hack demonstrations and the security implications of PLC exploits. The tag focuses on cybersecurity, vulnerability disclosures, and best practices for protecting PLC-based systems.
