Proliance Surgeons in Washington notified HHS that 437,392 patients were affected by a #ransomware attack that encrypted files and systems and resulted in some files being exfiltrated.
Their undated website notice about the incident does not disclose when the attack occurred or was first discovered, but it appeared to be earlier this year (circa February). They first notified HHS on November 20.
The information involved includes individual names, and one or more of the following: date of birth, Social Security number, medical treatment information, health insurance information, phone number, email address, financial account number, driver license or other identification information, and usernames and passwords.
I haven't seen any group claim responsibility for this breach and Proliance does not state whether they ever negotiated with the unnamed TAs or paid them. Has anyone seen any group claim responsibility for this one?
Questions to Proliance have been sent.
