Transport for London discloses ongoing “cyber security incident”

Transport for London (TfL) is investigating an ongoing cyber security incident; the agency reports no current evidence of customer data compromise and no impact to services, has notified the National Crime Agency and the NCSC, and implemented containment measures. The report also recalls a related May 2023 incident in which the Cl0p ransomware gang breached a supplier's MOVEit server and exposed contact details for ~13,000 customers.
