mj-donnais.fr Listed by lockbit3 Ransomware Group

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

mj-donnais.fr was listed on the lockbit3 ransomware leak site. The group claims to have stolen internal data.

— from LockBit’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.

On September 14, 2022, the French company mj-donnais.fr appeared on the LockBit 3.0 ransomware leak site. The listing states that internal files were exfiltrated during a ransomware attack, although the exact number of records affected and the specific types of data taken remain undisclosed by the group.

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 582 companies.

Details from the Leak Site

The primary disclosure on the LockBit 3.0 leak site indicates that mj-donnais.fr suffered a ransomware intrusion in which attackers successfully stole internal files before encrypting systems. No ransom amount, exact breach date, or sample data is shown in the public listing. The notification simply confirms that data was taken and warns that it will be published if the victim does not negotiate. As is typical with these sites, the listing does not quantify affected records or list individual data fields exposed.

Why This Matters for You and Your Family

When a company that handles customer orders, payments, or personal correspondence is breached, your information can easily be caught up in the stolen files. Even if the leak site does not publish every record, the mere claim of exfiltration creates long-term risk. Internal files often contain names, addresses, phone numbers, email accounts, order histories, and sometimes payment details. Once that information leaves the company’s control, it can surface months or years later in identity-theft operations or targeted scams aimed at you and your household.

Doxxing and Identity-Chain Risks

Stolen internal files frequently link multiple pieces of information that attackers can chain together. An email address found in one document can be matched to a username on a gaming platform, a phone number in a supplier spreadsheet, or a home address in an invoice. These connections allow criminals to build a complete profile for doxxing, account takeover, or spear-phishing. Credential leaks of this nature often cascade into gaming accounts belonging to you or your children, where stolen logins grant access to valuable in-game items, chat histories, and further personal details that tie back to the family’s real identity.

LockBit 3.0’s Known Track Record

Public reporting attributes the LockBit ransomware operation to a group that first appeared in 2019 and rebranded as LockBit 3.0 in 2022. The gang has targeted organizations across dozens of countries, routinely posting victim data on their leak site when ransom demands are not met. Their typical playbook involves initial access through compromised remote desktop credentials or vulnerable web applications, followed by lateral movement, data exfiltration, and deployment of ransomware. They then apply dual extortion pressure: threatening both system encryption and public release of stolen files. The group’s leak site has hosted data from hundreds of victims, making LockBit 3.0 one of the most active ransomware operations in recent years.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, with cleanup handled by the service.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure surfaces in hours rather than months.
  • Rotate any password you used at mj-donnais.fr or related services, replace it with a unique passphrase, and secure the account with 2FA through 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 data.
  • Let remediation specialists perform hands-on takedown requests across data brokers and leak repositories on your behalf.

The incident underscores that ransomware groups continue to treat stolen corporate data as leverage long after the initial attack. A single listing like this can feed identity theft and account takeovers for years. Starting with DoxxScan gives you continuous monitoring across 13.1B+ breach records and 100+ platforms, AI-powered identity-chain mapping, and hands-on remediation by specialists, including household coverage that protects both adult accounts and children’s gaming profiles.

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.
