Sunflower recently disclosed a cyberattack on its systems, revealing that hackers gained access on December 15 but remained undetected until January 7. 

During this time, sensitive personal and medical data — including names, addresses, dates of birth, Social Security numbers, driver’s license details, medical records, and health insurance information—were compromised. According to its filing with the Maine Attorney General’s Office, the breach impacted 220,968 individuals.

Meanwhile, CCA experienced a similar data breach in July last year. The organization reported that cybercriminals stole extensive patient information, including names, addresses, dates of birth, driver's license numbers, Social Security numbers, diagnoses, lab results, prescriptions, patient ID numbers, and provider details. The breach affected 114,945 individuals, as per its filing with Maine’s Attorney General’s Office.

The Rhysida ransomware group has claimed possession of 7.6TB of Sunflower’s data, including a 3TB SQL database, according to The Register. With the data still listed online, it suggests that either negotiations are ongoing or have collapsed. However, as of now, there is no confirmed evidence of the stolen data being misused on the dark web.

Following these incidents, both organizations have taken steps to strengthen cybersecurity measures to prevent future breaches.
