Nightingalehammerson

Nightingalehammerson was compromised in a ransomware attack attributed to kairos in December 2025. The organization, operating in an undisclosed sector in Unknown, was added to the group's data leak site as part of an extortion campaign.

kairos operates as a financially motivated ransomware-as-a-service (RaaS) operation, exfiltrating sensitive data and threatening public disclosure to pressure victims into paying ransom demands.

Nightingale Hammerson comprises two care homes, Nightingale House in Clapham and Hammerson House, Wohl Campus, in Hampstead. Our homes are welcoming, warm and comfortable but they are also a hive of activity and enjoyment. The care we offer is exceptional and our individually tailored approach to care offers a home-from-home for residential, nursing, dementia, respite and palliative care.
