Description

Ocelot Ventures, LLC, doing business as Excelas, disclosed that an unauthorized actor gained access to certain of its systems between November 27 and December 3, 2025. The company detected suspicious network activity on January 28, 2026, and promptly engaged third‑party cybersecurity experts to conduct an investigation. The investigation aimed to determine the scope and nature of the unauthorized access. Following the investigation, Excelas began notifying individuals who may have been affected by the incident. On May 12, 2026, the company filed a formal notice of the breach with the Commonwealth of Massachusetts. The timeline indicates a gap of approximately two months between the end of the suspected access period and the detection of suspicious activity.

According to Excelas, the data that may have been impacted includes names, dates of birth, Social Security numbers, government‑issued identification information, medical or health or diagnosis information, medication information, medical record images, insurance information, and payment information. The company stated that individuals who received an Excelas data breach notification may have had sensitive personal and protected health information exposed. Excelas provides medical record organization and document management services for healthcare providers, insurers, and law firms. The breach therefore potentially affects a broad range of individuals whose information is handled through those services. The types of information listed align with the categories of personal and protected health data typically managed in medical record organization workflows.

In response to the incident, Excelas retained third‑party cybersecurity experts to investigate the unauthorized access and to assist with containment and remediation. The firm also initiated a notification process to alert potentially affected individuals and provided them with information about the breach. Edelson Lechtzin LLP, a national class action law firm, announced that it is investigating potential claims arising from the Excelas breach and is offering free consultations to those who received a notification. The law firm has offices in Pennsylvania and California and handles a variety of class and collective actions in addition to data breach litigation.
