Malborough, MA-based ReproSource Fertility Diagnostics has suffered a ransomware attack in which hackers gained access to systems containing the protected health information of up to 350,000 patients.
ReproSource is a leading laboratory for reproductive health that is owned by Quest Diagnostics. ReproSource discovered the ransomware attack on August 10, 2021 and promptly severed network connections to contain the incident. An investigation into the security breach confirmed the attack occurred on August 8.
While it is possible that patient data was exfiltrated by the attackers prior to the deployment of ransomware, at this stage no evidence of data theft has been identified.
A review of the files on the affected systems was completed on September 24 and revealed they contained the following types of protected health information:
Names, phone numbers, addresses, email addresses, dates of birth, billing and health information (CPT codes, diagnosis codes, test requisitions and results, test reports and/or medical history information), health insurance or group plan identification names and numbers, and other information provided by individuals or by treating physicians. A small subset of individuals may have had driver’s license number, passport number, Social Security number, financial account number, and/or credit card number exposed.
Notification letters are now being sent to affected individuals by Quest Diagnostics. Complimentary credit monitoring and protection services are being provided to affected individuals, who will also be protected by a $1,000,000 identity theft insurance policy.
ReproSource said additional safeguards have been implemented to protect against ransomware and other cyber threats, including additional monitoring and detection tools.
