Interlock ransomware claims DaVita attack, leaks stolen data

Interlock ransomware claims to have exfiltrated roughly 1.5 TB (about 700,000 files) of data from DaVita, a major kidney dialysis provider, and has published the files on its dark web leak site after negotiations allegedly failed; DaVita says a full investigation is underway. The report highlights Interlock's evolving ClickFix social-engineering tactics that deliver info-stealers and RATs prior to encryptor deployment and urges vigilance while the leaked data's authenticity remains unverified.
