chs.ca Listed by lockbit3 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The chs.ca Listed by lockbit3 Ransomware Group (reported October 21, 2023) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
On October 21, 2023, the Canadian organisation chs.ca appeared on a leak site operated by the ransomware group lockbit3. Public reporting states that internal files were exfiltrated in a ransomware attack; the number of people affected remains unknown, and further technical details have not been disclosed.
The listing matters because chs.ca is associated with the Canadian Hearing Society, which supports deaf, deafened and hard-of-hearing people. Any exposure of internal material from such an organisation raises concrete questions about the privacy of clients, staff and partners, even while the precise scope stays unconfirmed.
Breaking down the breach
According to the available record, chs.ca was listed by lockbit3 on or about October 21, 2023. The only data description supplied is that internal files were allegedly exfiltrated in a ransomware attack. No figure for affected individuals has been published, no attack vector or initial access method has been confirmed, and no timeline of compromise or encryption has been released by the organisation or independent investigators in the material at hand.
The group’s own leak-site text characterises the victim as a “Greedy Company” that “dont care about their customers and emplyees data” and notes that the Canadian Hearing Society provides services intended to enhance the independence of deaf, deafened and hard-of-hearing people. That language is a claim by the threat actors, not an independently verified finding. Public detail on whether ransom negotiations occurred, whether data were later published in full, or whether the organisation confirmed the intrusion remains limited.
The group behind it: lockbit3
Lockbit3 is a well-documented ransomware operation that has functioned as a Ransomware-as-a-Service platform. Affiliates gain access to victim networks, exfiltrate data, and deploy encryption; the core group then hosts leak sites to pressure payment by threatening or carrying out public release of stolen files. The brand has been linked to numerous high-profile incidents across healthcare, education, manufacturing and public-sector targets in multiple countries.
Typical lockbit3 tactics include double extortion—combining encryption with data theft—and the use of automated negotiation portals and countdown timers on leak sites. The group has historically claimed responsibility by posting victim names, sample files and taunting statements. In this case the listing of chs.ca and the accompanying commentary constitute such a claim; they should be treated as unverified assertions by the actors rather than established fact about the organisation’s conduct or the full contents of any stolen archive.
Who is chs.ca?
chs.ca is the web presence of the Canadian Hearing Society (also known as CHS), a Canadian non-profit that delivers services aimed at improving the independence and quality of life of people who are deaf, deafened or hard of hearing. Organisations of this type commonly maintain client case files, contact details, appointment and service records, employment information for staff and volunteers, and internal administrative documents.
A breach affecting such an entity is consequential because the population it serves may already face communication barriers and heightened privacy sensitivities. Exposure of internal material can therefore affect not only operational continuity but also the trust and safety of individuals who rely on the organisation for essential support.
What data was at risk
The facts name only “internal files exfiltrated in ransomware attack.” No inventory of specific data categories—such as names, addresses, health or audiology records, financial details or employee information—has been publicly confirmed. Exact contents therefore remain unconfirmed.
In general, a service organisation working with deaf and hard-of-hearing clients would be expected to hold personal contact data, service-history notes, possibly health-related or accommodation information, and internal HR or administrative files. Whether any of those categories were among the exfiltrated material in this incident is not established by the available record.
What's at stake
For individuals, the principal risks are misuse of personal information that may have been present in internal files—identity fraud, unwanted contact, or exposure of sensitive service-related details. Because the scale is unknown, it is not possible to say how many people, if any, face direct exposure. For the organisation, stakes include operational disruption, potential regulatory scrutiny under Canadian privacy law, reputational harm, and the cost of investigation and remediation.
Even when encryption is reversed or systems are restored, the fact of exfiltration means copies of data may remain under the control of criminals. That lingering uncertainty is the core ongoing risk for anyone whose information might have been held by chs.ca.
What to do if you're exposed
If you have been a client, employee or partner of the Canadian Hearing Society, consider the following practical steps while official confirmation of affected individuals remains unavailable:
- Monitor financial and credit accounts for unfamiliar activity and consider a fraud alert if you believe sensitive identifiers could have been involved.
- Be alert to phishing or social-engineering attempts that reference hearing services, appointments or personal details that an attacker might have obtained.
- Request information directly from the organisation about whether your records were implicated once it issues formal notices.
- Change passwords on related accounts and enable multi-factor authentication where available.
- Run a free exposure scan of your email address to check whether it has already appeared in known breach datasets.
Public detail on this incident is still limited. Treat claims from the ransomware group as unverified, rely on official statements from chs.ca or Canadian authorities when they appear, and focus on the concrete protective measures above rather than speculation.

Publicly posted by lockbit — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
