Press / market disclosure — not a breach-notification filing

A media or market posting that confirms an incident but carries no breach-notification fields, so compliance clocks aren't assessable. The summary below is extracted from the coverage — verify against the source.

Standard Bank is discovering the extent of the cyberattack in the daily data dumps. Standard Bank: A cyberattack carried out by the malicious actor Rootboy resulted in the exfiltration of 1.2 terabytes of internal data from Standard Bank between late February and March 2026. Although the bank assured that its transactional systems remained secure, sensitive personal data of more than 154 million clients was compromised. Standard Bank is communicating with affected clients and proceeding with the preventive replacement of cards, while cooperating with regulatory authorities. Linked ransomware group: PrinzEugen.
