McCOR Listed by DragonForce Ransomware Group

If you are a customer of McCOR, here’s what is being claimed, and what it would mean for you.

McCOR was listed on DragonForce's leak site. DragonForce claims to have stolen internal data. This is the group's claim, not a confirmed finding.

McCOR Listed by DragonForce Ransomware Group

On April 15, 2026, Canadian real estate and property management firm McCor appeared on the leak site of the dragonforce ransomware group. Internal files were allegedly exfiltrated during a ransomware attack, and the company’s data is now publicly listed for anyone to access.

Already exposed?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

What Public Reporting Shows

Public reporting indicates that dragonforce added McCor to its leak site on April 15, 2026. The posting states that internal files were stolen before encryption occurred. No exact number of affected individuals has been disclosed, but the breach involves data from a firm that manages commercial, retail, and residential properties across Canada. Available reporting describes the exposed material as internal company files rather than a specific list of customer records, though such documents frequently contain tenant names, contact details, financial information, and lease agreements.

McCor provides investment management, leasing, project management, and advisory services to real estate developers and tenants. Any records taken could therefore include personal information belonging to landlords, tenants, vendors, and employees.

Why This Matters for You and Your Family

When a property management company loses control of internal files, the people whose information sits in those files are placed at immediate risk. If you rent or own property managed by McCor, your name, address, phone number, email, bank details, or lease documents may now be in the hands of criminals. The same applies if you have ever done business with one of their clients.

Unverified claim — what this report is

This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
