Boston Children's physician group suffers data breach
Boston Children’s Health Physicians notified patients and the public of a Sept. 6 data breach of its systems, caused by an IT vendor. The multispecialty group said in a statement that it immediately deployed cyberattack response protocols once it became aware of the incident.
The unnamed IT vendor alerted Boston Children’s to suspicious network activity, after which an investigation showed an unauthorized third party had gained access to systems and stolen data files.
The information taken included the names, dates of birth, Social Security numbers, insurance and billing information, driver’s license numbers, and medical record numbers from employees and patients. However, the electronic health record was not breached, meaning clinical data on patients was not stolen, Boston Children’s said.
Hacker group BrianLian claimed responsibility for the attack on a dark web forum, where the data is likely to be put up for sale.
BianLian has claimed responsibility for 60 ransomware incidents so far this year, data from Comapritech shows. However, there is no evidence ransomware was deployed in the breach at Boston Children’s.
The physician group said it worked with a cyber forensics agency to investigate the attack. That investigation appears to now be concluded, as Boston Children’s started sending letters to impacted patients on Oct 4.
