Collge Superieur De Montreal Listed by rhysida Ransomware Group

On November 24, 2025, Collège Supérieur de Montréal appeared on the leak site of the Rhysida ransomware group after the attackers exfiltrated internal files from the Canadian post-secondary institution.

What's Publicly Reported from Reporting

Public reporting indicates the college was listed on the Rhysida leak portal hosted via ransomware.live. The group claims to have stolen internal documents during a ransomware incident. No exact victim count has been disclosed, and the precise volume or sensitivity of the files remains unclear from available information. The listing appeared on November 24, 2025, consistent with Rhysida’s typical pattern of publishing victim data after an initial extortion window.

Available reporting describes the exposed material as internal files. Because the college serves students, faculty, and administrative staff, any personnel records, application forms, or vendor contracts contained in those files could include names, contact details, dates of birth, and financial information.

Why This Matters for You and Your Family

When a school or college suffers a breach, the people most affected are often students, parents, alumni, and nearby residents whose personal information was stored in the institution’s systems. If your child attends or has applied to Collège Supérieur de Montréal, or if you have ever taken a course, worked there, or been listed as an emergency contact, your data may now sit on a ransomware leak site. Internal files frequently contain more than just names; they can hold addresses, phone numbers, email accounts, and sometimes Social Insurance Numbers.

Once that information reaches criminal marketplaces, it rarely stays isolated. A single leak can supply the missing piece that links your email address to your home address, your children’s names, or your banking details. For ordinary families this means higher risk of identity theft, targeted phishing, or unwanted exposure of private matters.

The Doxxing and Identity-Chain Implications

Ransomware groups like Rhysida do not always publish every file they steal. They often keep the most sensitive material for targeted extortion or sell it quietly on underground forums. Even a modest leak of internal files can seed an identity chain: an attacker starts with one email address from the college breach, finds the same password reused on a gaming platform, then maps that gamer tag to a child’s real name and home address. The result is doxxing that can affect every member of a household.

Credential leaks like this one cascade into account takeovers and doxxing chains, especially when gaming accounts are involved. Children’s usernames, chat logs, or linked email addresses become easy stepping stones for harassers or identity thieves. What begins as a school breach can quickly become a family-wide privacy emergency.

Rhysida’s Publicly Known Track Record

Public reporting attributes Rhysida’s emergence to mid-2023. The group has since claimed responsibility for attacks on healthcare providers, municipalities, and educational institutions across several countries. Notable prior victims include hospitals and local governments whose patient records and employee data were later published when ransom demands went unpaid.

Rhysida’s typical playbook involves initial access through phishing or exploited remote desktop services, followed by exfiltration of internal files before encryption. The group then demands payment and, if unmet, publishes samples or full datasets on its leak site. Extortion pressure is applied through both data publication and direct contact with victims or their clients.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real-world identity so you can see exactly what the Collège Supérieur de Montréal breach may have exposed about you.
• Rotate any password you used at the college or similar educational portals anywhere it has been reused, and switch on two-factor authentication through an authenticator app rather than SMS.
