RE/MAX 1st Choice Listed by Gammax Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to target professional services firms that hold concentrated stores of client and operational data, using leak-site listings to pressure victims even when full technical details remain sparse. In that landscape, a recent claim involving a Florida real-estate brokerage illustrates how quickly such incidents surface publicly and how little confirmed information often accompanies them at first.

RE/MAX 1st Choice has been listed by the Gammax ransomware group, according to reporting dated July 30, 2026. Public detail is limited: the number of people affected is unknown, and the only description of exposed material is that internal files were exfiltrated in a ransomware attack. The listing itself is a claim by the group rather than an independently verified confirmation of every asserted detail.

Breaking down the breach

What is known rests on the Gammax listing and the accompanying summary. RE/MAX 1st Choice appears on the group’s leak site in connection with a ransomware attack in which internal files were said to have been taken. The report is dated July 30, 2026. No public figure has been given for the number of individuals affected, no attack vector or initial access method has been disclosed, and no timeline of intrusion, encryption, or negotiation has been released. Beyond the statement that internal files were exfiltrated, the precise scope, volume, or categories of material remain unconfirmed in the available record.

Because the primary source is a threat-actor listing, the incident should be treated as an asserted claim pending further corroboration from the organisation or independent investigators. No dollar amounts, file counts, or sample data releases are described in the facts at hand.

Who is Gammax?

Gammax is known publicly as a ransomware and data-extortion operation that follows a familiar double-extortion pattern: encrypting systems where possible and exfiltrating data to threaten publication if payment is not made. Like other groups in this category, it maintains a leak site on which it names victims and, in some cases, posts samples or larger archives to demonstrate possession of stolen material. Public reporting on Gammax has generally described opportunistic targeting across sectors rather than a narrow industry focus, with pressure applied through timed disclosure threats.

For this incident, the only specific assertion tied to RE/MAX 1st Choice is the group’s own listing and the claim of internal-file exfiltration. No additional statements, screenshots, or unique demands attributed to Gammax about this particular victim appear in the provided facts. Readers should therefore separate well-documented patterns of how such groups operate from the still-unverified particulars of any single listing.

RE/MAX 1st Choice and its sector

RE/MAX 1st Choice is a Florida real-estate brokerage established in 2005 and managed by Katy and John Martinelli as owners and operators. It operates within the residential and commercial property market, a sector that routinely handles identity documents, financial records, property details, and correspondence tied to buyers, sellers, and agents. Brokerages of this type typically sit at the intersection of multiple parties—clients, lenders, title companies, and contractors—so a compromise can touch data that extends beyond a single firm’s own employees.

A breach claim against a local or regional RE/MAX franchise matters because real-estate transactions concentrate sensitive personal and financial information in relatively compact organisations. Even when the exact contents of a theft remain undisclosed, the sector’s normal data holdings make such incidents consequential for clients and staff who may have shared documents in the course of ordinary business.

The information in question

The facts state only that internal files were exfiltrated in a ransomware attack. No further breakdown—such as whether the material included client databases, contracts, employee records, financial ledgers, or email archives—has been publicly named. The number of people affected is unknown.

Organisations in residential real estate commonly hold names, contact details, government-issued identification, mortgage and banking information, property addresses, and transaction histories. That is the type of material such a firm would typically possess; it is not a confirmation that any specific category was taken in this case. Until the organisation or a credible investigation publishes a clearer inventory, the exact contents remain unconfirmed.

The real-world impact

For individuals, the practical risks centre on misuse of any personal or financial data that may have been among the internal files. That can include targeted phishing that references a real property transaction, attempts at identity fraud, or social-engineering calls that sound legitimate because they draw on accurate details. Because the scale and data types are undisclosed, people who have done business with the brokerage cannot yet know from public sources whether their own information was involved; caution is therefore warranted without assuming the worst.

For the organisation, a ransomware event that includes exfiltration typically brings operational disruption, potential regulatory notification duties, reputational strain, and the cost of investigation and remediation. Client trust in a brokerage depends heavily on confidential handling of transaction documents; even an unverified listing can prompt inquiries and require clear internal and external communication. None of these outcomes establish negligence as fact; they are the ordinary consequences that follow when a professional-services firm is named in a ransomware claim.

Were you affected?

If you have been a client, counterparty, or employee of RE/MAX 1st Choice, treat the situation as a prompt for basic hygiene rather than proof that your data was taken. Monitor financial and credit accounts for unfamiliar activity, be sceptical of unexpected messages that reference property deals or request urgent payment or personal details, and consider placing fraud alerts if you have shared sensitive documents with the firm. Prefer official channels if you need to confirm the status of any transaction.

You can also run a free exposure scan of your email address to check whether it has already appeared in known breach datasets. That step will not confirm or rule out involvement in this specific incident, but it can show whether your address is circulating more broadly and help you prioritise password changes and monitoring.
