The Clop ransomware group claims to have stolen 270 GB of data from Harley-Davidson by exploiting a vulnerability (CVE-2026-12569) in the Windchill product lifecycle management software. This breach highlights a widespread risk as over 40 companies have been targeted in the same campaign, urging Windchill and FlexPLM users to take urgent mitigation actions.

This Wire brief sits within Fusion42's coverage of Security: Cybersecurity.

◆ The Wire takeaway

The attack forces you running Windchill or FlexPLM to urgently patch and audit your systems; ignoring this vulnerability risks regulatory backlash and market trust erosion.
