Data Breaches Reported by Manchester Ophthalmology, UnitedHealthcare, and Cook County Health
Manchester Ophthalmology in Connecticut has experienced a cyberattack in which the attackers may have gained access to patient information. The eye care provider became aware of the cyberattack on November 25, 2019 when employees noticed unusual activity on the network. Assisted by a third-party technology firm, it was determined later that day that hackers had gained access to its systems and attempted to deploy ransomware. Access was first gained to the network on November 22, 2019 and continued until November 25.
The investigation found no evidence to suggest any patient information was accessed or downloaded by the attackers, but during the investigation it was determined that certain patient information had not been backed up and could not be recovered. The types of data lost included names, patient-created medical histories, and details of the care those patients received at Manchester Ophthalmology.
Patients have been advised to exercise caution and monitor their accounts and explanation of benefits statements for any sign of fraudulent use of their information. Manchester Ophthalmology has provided further training to employees to ensure the proper backup of all information.
The breach report submitted to the Department of Health and Human Services’ Office for Civil Rights indicates up to 6,846 patients were affected by the security breach.

2,713 Individuals Informed of Cook County Health Mailing Error
Chicago, IL-based Cook County Health has started notifying 2,713 individuals that some of their protected health information was sent to a third-party vendor in error. The information related to individuals participating in a #keepingitLITE study and was sent to a vendor who was due to assist with mailing study information.
The list of study participants, which was limited to names, addresses, and email addresses, was sent before a business associate agreement was in place. A business associate agreement confirms that a vendor agrees to implement safeguards to ensure the privacy and security of any information. Without the BAA, satisfactory assurances that those safeguards were in place had not been received by Cook County Health.
Action has now been taken to ensure similar errors are prevented in the future.
