IN: Cummins Behavioral Health Systems discovers cyberattack when it finds ransom note

Sometime between Feb. 2 and March 9 of this year, Cummins Behavioral Health Systems (CBHS) in Indiana became a victim of a cyberattack.

CBHS is a private not-for-profit organization providing behavioral health services in Boone, Hendricks, Marion, Montgomery, Putnam, and surrounding counties in Central and West Central Indiana. It provides care to persons of all ages in a variety of office and community-based settings, including school-based services for students with mental health issues.

CBHS discovered the incident when they found a ransom note in their environment on March 9. There was no encryption of data. CBHS does not name the attackers or say whether they paid the demanded ransom, but there’s no language about getting any assurances about deletion of data, so they probably didn’t pay.

The types of information that may have been accessed or acquired included: names, addresses, dates of birth, driver’s license/State ID numbers, Social Security numbers, financial account information, payment card information, usernames and passwords, health insurance information and medical information.

CBHS has notified the Maine Attorney General’s Office that 157,688 people were affected. They have been offered mitigation services in a letter sent to those affected on August 11. There is also a notice on CBHS’s website, but that notice does not mention the mitigation services.

CBHS does not explain why it took five months from date of discovery to notify those affected, but there was no delay requested by law enforcement in this case.
