Prelys Courtage Listed by anubis Ransomware Group: What Was Exposed & What To Do

People who have dealt with Prelys Courtage may now face uncertainty about whether personal or financial details held by the firm have left its control. Public reporting describes a client data breach tied to a ransomware incident in which internal files were taken, yet the number of people affected and the precise contents of those files remain unknown.

On 28 July 2026 the organisation appeared on a listing associated with the anubis ransomware group. For clients and counterparties, the practical question is straightforward: what information may now be in unauthorised hands, and what steps reduce the resulting risk.

Inside the incident

According to the available record, Prelys Courtage was listed by the anubis ransomware group on 28 July 2026. The reported summary characterises the event as a client data breach at a major mortgage brokerage franchise. The facts state that internal files were exfiltrated in a ransomware attack. No confirmed figure for the number of people affected has been published, and public detail does not describe the intrusion method, the duration of unauthorised access, or any ransom demand. The listing itself is a claim by the group; independent confirmation of the full scope has not been supplied in the material at hand.

Who is anubis?

Anubis is a ransomware operation known in public reporting for double-extortion tactics: encrypting systems while also copying data and threatening to publish or sell it if payment is not made. Groups operating under this model commonly maintain leak sites where they name victims and, in some cases, release samples or larger archives. Their tooling and affiliate structures have evolved over time, but the core pattern remains pressure through both operational disruption and the exposure of stolen files. With respect to Prelys Courtage, the only specific assertion on record is the group’s own listing of the organisation; no further claims by anubis about this victim are documented in the facts provided.

Prelys Courtage and its sector

Prelys Courtage operates as a mortgage brokerage franchise. Firms in this sector intermediate between borrowers and lenders, collecting and retaining substantial volumes of personal, financial and property-related information in the ordinary course of arranging home loans and related products. That typically includes identity documents, income and employment records, bank details, credit information and correspondence about individual transactions. Because the business sits at the centre of high-value, long-lived financial relationships, a breach that reaches internal files can affect not only the brokerage’s own operations but also the privacy and security of clients, guarantors and, in some cases, employees or partner lenders. The consequential nature of such an incident stems directly from the sensitivity and longevity of the data these organisations must hold to perform their regulated function.

What was likely exposed

The facts name the exposed material as internal files exfiltrated in a ransomware attack and describe the event as a client data breach. Beyond that characterisation, the exact data types, file counts and affected populations are not disclosed. Organisations of this kind ordinarily process identity particulars, contact details, financial statements, loan application packs and related internal records. It is therefore reasonable to expect that some combination of client and operational information could have been among the taken files, yet that remains an inference rather than a confirmed inventory. Readers should treat any specific claim about named data elements as unconfirmed until the organisation or a competent authority publishes a verified account.

Why it matters

For individuals, the real-world risks centre on misuse of personal and financial information: targeted phishing that appears to come from a trusted mortgage adviser, attempts to open credit or refinance products in someone else’s name, or social-engineering attacks that exploit knowledge of a property purchase or existing loan. Even partial files can supply enough context to make fraudulent contact convincing. For the organisation, consequences include regulatory notification duties, potential contractual exposure to lenders and clients, operational disruption from the ransomware event itself, and the longer-term task of restoring confidence. None of these outcomes require dramatic language; they follow ordinary patterns observed whenever sensitive intermediary data leaves authorised systems.

Were you affected?

If you are a current or former client of Prelys Courtage, or have supplied documents to the firm in connection with a mortgage application, consider the following practical steps:

• Monitor bank and credit-card statements for unfamiliar activity and enable transaction alerts where available.
• Treat unexpected emails, calls or messages that reference a loan or property transaction with caution; verify through a known official channel before responding or opening attachments.
• Consider a credit freeze or fraud alert with the relevant credit-reference agencies if you believe high-risk data may have been involved.
• Retain any breach notification you receive from the firm and follow its specific instructions on password changes or document re-issuance.
• Run a free exposure scan of your email addresses to check whether they have already appeared in known breach datasets elsewhere.

Public detail on this incident remains limited. Further clarity, if it comes, will most likely arrive through official statements from Prelys Courtage or from supervisory authorities. Until then, measured vigilance is the proportionate response.
