Data compromised
Corporate archives and downstream consumer-notification cohorts as later inventory work matured
Technical writeup
Johnson Controls International and the parallel `johnson-controls` directory entry describe the same September 2023 enterprise ransomware and exfiltration wave attributed in security journalism to Dark Angels, with multi-terabyte theft claims and nine-figure remediation costs tracked across 2024–2025 filings. This row exists so visitors landing on the `johnson-controls-international` company slug still see the canonical incident without duplicating forensic novelty.
Root cause
Human-operated ransomware with bulk data theft (per vendor and trade-press narratives)
