Researchers working on Project Basecamp found significant security issues with programmable logic controller (PLC) Some PLCs were too brittle and insecure to even tolerate security scans and probing. The D20 ME PLC by General Electric, a widely deployed industrial system, fared the worst. Wightmans analysis of the device revealed that the D20 relied on both hardware and firmware that was more than two decades old and was rife with hidden back door administrative accounts, remotely exploitable vulnerabilities.”]
