PTC Windchill Vulnerability Exploited in Ransomware Campaign

A critical unsafe-deserialization vulnerability in PTC Windchill is being actively exploited in a ransomware campaign. The flaw allows attackers to execute arbitrary code remotely without authentication. Windchill is widely used for product lifecycle management in manufacturing and engineering environments, making exploited instances potentially exposed to production-impacting ransomware deployment. Organizations running Windchill should prioritize patching and check for signs of compromise given confirmed active exploitation.
