CCMC Listed by Medusa Ransomware Group

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

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

On September 23, 2025, community association management firm CCMC appeared on the leak site of the Medusa ransomware group, with internal files reportedly exfiltrated during a ransomware attack. The Scottsdale, Arizona-based company, founded in 1973, manages residential communities, municipal and utility districts, commercial associations, and provides pre-development consulting services nationwide. With 738 employees, the breach potentially exposes sensitive records belonging to homeowners, association members, employees, and business partners whose personal and financial details were stored in the compromised systems.

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 Medusa posted CCMC to its data leak site on September 23, 2025. The company’s headquarters is located at 8360 East Vía de Ventura #100, Scottsdale, AZ 85258. Available reporting describes the exposed material as internal files exfiltrated during the ransomware incident. The exact number of individuals whose records were taken remains unknown, and the full scope of the stolen data has not been publicly detailed beyond the broad category of internal files.

Why This Matters for You and Your Family

If you live in a neighborhood, condominium, or homeowners association managed by CCMC, your address, payment history, contact information, or other records may have been among the files taken. The same applies if you or your spouse works for one of the communities, districts, or developers that rely on CCMC’s budgeting, governance, or amenity-planning services. 738 employees and countless association members now face the risk that their personal data could be used for identity theft, phishing, or further extortion. When a company that handles so many household records is breached, the impact reaches far beyond the office walls and directly into family finances and privacy.

The Doxxing and Identity-Chain Implications

Ransomware leaks like this one rarely stop at the initial data set. Stolen internal files often contain spreadsheets that link names, addresses, emails, phone numbers, and sometimes dates of birth or financial details. Attackers and opportunistic criminals can chain this information with usernames found on other platforms, turning a single breach into a map of your online and offline identity. Credential leaks of this nature frequently cascade into account takeovers, especially for gaming accounts belonging to you or your children. A compromised email or reused password can give attackers access to Discord, Steam, Roblox, or other services where kids share personal details, quickly linking back to the family home address exposed in the CCMC files.

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.
