Full timeline through 2026
2023 — Capita outsourcing breach; Black Basta disclosures
Cataloged incident. UK outsourcing giant Capita absorbed a late-March 2023 Black Basta intrusion that lingered on networks for roughly ten days before containment, later forcing pension clients—including Diageo's defined-benefit arrangements—to warn tens of thousands of members about likely theft of national insurance numbers, addresses, and birthdates. Diageo correspondence summarized Capita's May 2023 admission that member files were probably compromised and funded Experian monitoring for exposed cohorts. Exposed categories include National Insurance numbers, home addresses, and DOBs referenced in Computing and successor member letters. BreachHistory cites approximately 30K+ affected records in this row. See the diageo-capita-pension2023 and canonical BreachHistory entry.
