Prelys Courtage Listed by Anubis Ransomware Group

On July 28, 2026, French mortgage brokerage Prelys Courtage was listed on the leak site of the Anubis ransomware group. The extortion actors publicly claimed to have exfiltrated internal files during a ransomware attack on the company, which operates as a major mortgage brokerage franchise handling client financing and real-estate loans across France.

Reported Details from the Leak Site

The Anubis leak page states that Prelys Courtage suffered a ransomware intrusion in which internal files were successfully exfiltrated. The listing does not disclose the exact number of affected individuals, nor does it specify the precise data types contained in the stolen files. It simply states that client data was impacted in the breach. The group has not published any sample files at the time of the initial listing, which is consistent with their current playbook of using the threat of full data release to pressure victims into payment. The disclosure indicates the incident is part of an active extortion campaign rather than a simple data dump.

Why This Matters for You and Your Family

If you have worked with Prelys Courtage for a mortgage, loan refinancing, or real-estate transaction, your personal and financial information may now sit in an attacker-controlled archive. Mortgage files routinely contain full names, dates of birth, home addresses, phone numbers, email addresses, national identification numbers, income details, bank account information, and copies of identity documents. Even though the exact volume of records is unknown, the exposure of this combination of data creates immediate risk for identity theft, loan fraud, and targeted phishing. Families who used the brokerage in the past several years should assume their information is at heightened risk until proven otherwise.

Doxxing and Identity-Chain Implications

Mortgage data is particularly dangerous because it links real-world identity to financial behavior and physical location. Attackers can combine the Prelys Courtage files with other leaked datasets to build complete identity chains — mapping your email addresses and phone numbers to usernames on social media, gaming platforms, and shopping sites. This chaining process often leads to doxxing, account takeovers, and swatting attempts. Credential leaks of this nature frequently cascade into gaming accounts belonging to you or your children, where stolen emails and passwords are tested for reuse, resulting in further exposure of private messages, friend lists, and sometimes home addresses.

Anubis Ransomware Group Track Record

Public reporting attributes the emergence of Anubis to late 2024. The group has rapidly built a reputation for targeting mid-sized European service firms, including financial intermediaries, insurance brokers, and professional services companies. Their typical playbook involves initial access through phishing or exploited remote desktop services, followed by rapid exfiltration of sensitive folders before encryption. Anubis then uses a double-extortion model: they threaten both operational disruption through encryption and public release of stolen client data. The group maintains an active leak site and frequently updates it with countdown timers, a tactic designed to create urgency for victims. While not yet among the largest ransomware operations, Anubis has shown consistent growth in both volume and the sensitivity of data they claim to hold.

What to do

• Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, including cleanup of exposed records.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next leak exposing you is caught in hours rather than months.
• Rotate any password you have ever used at Prelys Courtage or related mortgage portals anywhere it is reused, and switch to 2FA using an authenticator app instead of SMS.
• Cover the entire household with DoxxScan family protection, which extends to dependents and children’s gaming accounts that often chain back to the same breached email or address.
• Let remediation specialists handle data-broker takedown requests and opt-out processes that would otherwise require dozens of manual submissions.

The Prelys Courtage breach is a clear reminder that even specialized financial service firms remain high-value targets whose compromises directly threaten ordinary families’ financial privacy. Taking deliberate protective steps now can break the identity-chain before criminals monetize the data. DoxxScan by GalaxyWarden provides continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts at risk from cascading credential leaks like this one.
