BianLian ransomware claims attack on Boston Children’s Health Physicians

The BianLian ransomware group has claimed the cyberattack on Boston Children’s Health Physicians (BCHP) and threatens to leak stolen files unless a ransom is paid.

BHCP is a network of over 300 pediatric physicians and specialists operating over 60 locations across New York’s Hudson Valley and Connecticut, offering patient care in clinics, community hospitals, and health centers affiliated with Boston Children’s Hospital.

According to the announcement BHCP published on its website, a cyberattack compromised its IT vendor on September 6 and a few days later BHCP detected unauthorized activity on its network.

“On September 6, 2024, our IT vendor informed us that it identified unusual activity in its systems. On September 10, 2024, we detected unauthorized activity on limited parts of the BCHP network and immediately initiated our incident response protocols, including shutting down our systems as a protective measure.” –
