tdsb.on.ca Listed by lockbit3 Ransomware Group
If you are a customer of tdsb.on.ca, here’s what is being claimed, and what it would mean for you.
The Toronto District School Board, also known under the acronym of TDSB, is the largest school Board in Canada and the fourth largest in North America
— from LockBit’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.
Editor’s note: The claims described below originate from a ransomware group’s leak-site posting and have not been independently verified by GalaxyWarden. A listing of this kind is an assertion made by the group during an extortion attempt. It is not evidence that a breach occurred, and we report it as a claim rather than as a finding.

On June 10, 2024, the Toronto District School Board appeared on the LockBit 3.0 ransomware leak site, claiming that internal files had been exfiltrated during a ransomware attack on tdsb.on.ca. The listing states that data was stolen but does not specify the volume of records or the exact types of files taken. Anyone whose personal information, student records, or employment details are held by Canada’s largest school board may now face heightened risk of identity theft and doxxing.
Reported Details from the Listing
The LockBit 3.0 leak page explicitly names the Toronto District School Board and states that internal files were exfiltrated following a ransomware intrusion. No victim count is provided, and the disclosure does not list specific data categories such as names, addresses, Social Insurance Numbers, student grades, or employee payroll information. The posting follows the group’s standard format: an announcement of successful data theft with samples or full archives made available to pressure the victim. Publicly accessible mirrors of the leak site, tracked by ransomware.live, first indexed the TDSB entry on June 10, 2024.
Why This Matters for You and Your Family
If you or your children attend or work within the TDSB system, your information is likely stored in the very files now held by attackers. School boards maintain permanent records that include full legal names, home addresses, dates of birth, parent contact details, medical notes, and sometimes Social Insurance Numbers for staff. Once exfiltrated, this data does not expire. It can be sold quietly on dark-web forums or used immediately for targeted fraud, account takeovers, or spear-phishing campaigns against families. The breach therefore touches not only current students and employees but also alumni and former staff whose records remain archived.

Doxxing and Identity-Chain Risks
School-board data is especially dangerous because it creates direct links between real-world identities and online handles. A child’s student ID or parent email can be cross-referenced with gaming accounts, social-media profiles, and family addresses. Attackers routinely chain these pieces together: an email from the breach leads to a reused password on a gaming platform, which yields chat logs containing additional personal details, which in turn expose the household’s physical location. The result is persistent doxxing that can affect college applications, employment background checks, or even physical safety years later. Credential leaks like this one cascade into account takeovers and doxxing chains that conventional breach alerts rarely catch in time.
LockBit 3.0 Track Record
Public reporting attributes the LockBit 3.0 variant to a ransomware-as-a-service operation that first appeared in 2020 and rebranded after law-enforcement pressure in early 2022. The group has claimed responsibility for attacks on hundreds of organizations worldwide, including hospitals, manufacturers, and several other North American school districts. Their typical playbook begins with initial access gained through compromised credentials or exploited remote-desktop services, followed by rapid lateral movement, data exfiltration, and then dual extortion: threatening both encryption and public release of stolen files. LockBit 3.0 operators frequently set short payment deadlines and auction unsold data on their leak site when victims refuse to pay.
What to do
- Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup handled by specialists.
- Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure surfaces in hours rather than months.
- Rotate any password you have used on tdsb.on.ca or related TDSB services anywhere it is reused, and switch to 2FA through an authenticator app instead of SMS.
- Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often chain back to the same breached school records.
- Let remediation specialists manage takedown requests for any exposed personal documents appearing on data-broker or extortion sites.
The TDSB incident demonstrates that even large, well-known public institutions remain vulnerable, and the data they hold about your family can surface without warning on ransomware leak sites. Staying ahead requires more than reactive checks; it demands continuous visibility and expert intervention. DoxxScan by GalaxyWarden delivers exactly that through continuous monitoring across 13.1B+ breach records and 100+ platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and household coverage that includes children’s gaming accounts. Start your DoxxScan trial today to close the gaps before the next breach exposes you.

Leaked data cannot be deleted from the internet — anyone claiming otherwise is lying. Broker listings can be removed. We do the second, and show you exactly what to fix from the first.
