Threat-actor claim — not a regulatory filing

This row is a claim by the ransomware group Karakurt on its public extortion blog. It has not been validated by the victim or any regulator. Treat attribution and counts as the threat actor's assertion until a regulatory filing or victim disclosure corroborates them.

Post text · scraped from the leak site

The Petaluma Health Center is a Federally Qualified Health Center that strives to care for the "whole" individual by providing excellent care for all patients, regardless of one's ability to pay for services. We do not know whether their patients personal and medical information was stored unsafely because of their disability to pay but we have almost 490GB of this Health Center on our servers. Along with that we've obtained a good amount of financial information (numerous declarations, payment docs, tax forms ...) and personal employees information (SSNs, passports, phone numbers, addresses etc).That is going to be interesting.
