Health IT vendor breach exposes 442,000 patients’ data

A data breach at Unlimited Technology Systems, a vendor for practice management and revenue cycle software, exposed the personal and medical information of at least 442,000 patients in an October 2025 hack. The breach occurred between October 5 and October 10, with an unauthorized actor accessing files during that period. This incident underscores the growing threat of cyberattacks on healthcare IT vendors, which can have far-reaching implications for patient privacy and trust in the healthcare system.
