Six months after the Log4j vulnerability shocked the cybersecurity community, its risks to OT and ICS environments remain significant. The flaw, CVE‑2021‑44228, allows remote code execution in systems using Apache’s widely deployed Java logging library. Its discovery revealed how deeply embedded Log4j is across critical infrastructure, making remediation complex and ongoing. Despite global response efforts, many OT assets remain difficult to patch due to operational constraints, leaving organizations exposed to potential attacks. Continuous monitoring, asset visibility, and long‑term mitigation strategies are essential to managing the lingering risks.
