Full breach record for Apollo Hospitals

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.

Apollo Hospitals: A sample of the Agenda ransomware used by the Qilin group suggests that the Apollo Hospitals healthcare provider was the victim of a cyberattack that notably affected a Veeam backup environment. The victim-specific Tor negotiation site is no longer accessible. Linked ransomware group: killsec.
