Full timeline through 2026
2023 — Dark Angels ransomware; multi-TB exfiltration claims; delayed consumer notices
Unverified claim — treat actor counts cautiously. Johnson Controls International disclosed a September 2023 enterprise ransomware and data-exfiltration event attributed in security journalism to the Dark Angels group, with actors claiming tens of terabytes of archival theft, eight-figure ransom demands, and follow-on remediation costs above $27 million in vendor financial reporting. Late-2024 and 2025 coverage tracked long-cycle identity-notification programs as forensic scope matured. Exposed categories include Corporate and building-systems adjacent records described across law-firm summaries—field-level public mapping varies by notice cohort. No attested victim count is published for this row yet. See the johnson-controls-darkangels2023 and canonical BreachHistory entry.
