Ambleside Listed by Anubis Ransomware Group

On March 23, 2025, the Anubis ransomware group added Ambleside to its leak site, claiming that it had exfiltrated internal files containing the personal data of patients, company employees, and records of dozens of incidents that include patient abuse.

What Public Reporting Shows

Public reporting indicates the incident stems from a ransomware attack in which attackers gained access to Ambleside’s systems, copied sensitive internal documents, and later published a sample on their dark-web leak portal. The exposed material includes personal information belonging to both patients and staff as well as detailed records of multiple reported incidents, some describing cases of patient abuse. Available reporting describes the volume of affected individuals as currently unknown, with no confirmed count of unique patient or employee records released by either the victim organization or the threat actors.

Patient names, employee details, and incident reports appear among the stolen data according to the sample files posted. The leak site entry carries a typical ransomware extortion structure, although no specific ransom deadline had been publicly disclosed at the time of initial reporting.

Why This Matters for You and Your Family

When a healthcare or care-provider organization suffers a breach, the information exposed often includes the exact details needed to commit identity theft, open fraudulent accounts, or target family members with phishing and social-engineering attacks. If you or a loved one received care at Ambleside, your medical history, contact information, and possibly financial details may now sit in an attacker-controlled archive. Children’s records, when included, can remain valuable to criminals for years because minors’ credit files are rarely monitored.
