US HEALTHCARE DIAGNOSTIC FIRM SAYS 140,000 AFFECTED BY DATA BREACH

Summary from the TLDR InfoSec newsletter

Everest ransomware actors accessed Vikor Scientific (now Vanta Diagnostics) data via revenue cycle vendor Catalyst RCM, using compromised credentials to steal about 12GB of files containing names, dates of birth, payment card data, medical details, and insurance information. Roughly 140,000 individuals are currently listed as affected, but the final impact may be higher as counts from all linked entities remain unclear.
