Excelsior Orthopaedics, LLP (“Excelsior”), a healthcare provider with 10 locations across western New York, has reported a major cybersecurity incident impacting 394,752 individuals, including patients and employees of its affiliated entities Buffalo Surgery Center and Northtowns Orthopedics. The breach, which stemmed from a hacking attack, exposed highly sensitive personal and medical information.

Excelsior Orthopaedics Data Breach Details

Excelsior reported that it detected unusual activity on its network on June 23, 2024, and determined that an unauthorized party had gained access to its IT systems. The intrusion was classified as an external system breach (hacking). The company engaged a third-party cybersecurity firm to contain the attack, conduct forensic analysis, and assess the extent of the data compromise.

In response to the breach, Excelsior stated that it has:

  • Contained the intrusion and secured its network

  • Engaged cybersecurity and forensic experts to investigate

  • Notified law enforcement and relevant regulatory authorities

  • Offered 12 months of free credit monitoring and identity theft protection through CyberScout, a TransUnion company

  • Full names

  • Dates of birth

  • Driver’s license or state identification numbers

  • Social Security numbers

  • Medical records and health information

  • Health insurance details

This type of data is particularly valuable to cybercriminals and can be exploited for medical identity theft, tax fraud, and other forms of financial crime.

Total Number of Individuals Affected

The investigation confirmed that this was a large-scale breach, impacting 394,752 individuals in total.
