donbosco-landser.net Listed by ransomhub Ransomware Group

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

donbosco-landser.net was listed on Ransomhub's leak site. Ransomhub claims to have stolen internal data. This is the group's claim, not a confirmed finding.

donbosco-landser.net Listed by ransomhub Ransomware Group

On September 20, 2024, the French private school Ecole Collège Lycée donbosco-landser.net appeared on the leak site of the RansomHub ransomware group. The listing states that internal files were exfiltrated during a ransomware attack. The number of records affected remains unknown, and the precise data types have not been detailed beyond the generic description of internal files.

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 582 companies.

Reported Details from the Listing

The RansomHub leak page, accessible via the onion link hosted on ransomware.live, explicitly names the victim as Ecole Collège Lycée donbosco-landser.net. It states the incident involved a ransomware deployment followed by data exfiltration. No sample files have been published at the time of the listing, and the disclosure does not quantify how many students, parents, or staff may be impacted. The school’s public website indicates it serves families across primary, middle, and high-school levels in the Landser area of France.

Internal files exfiltrated is the only description provided. The listing does not specify whether student records, staff payroll, medical information, or financial documents were taken.

Why This Matters for You and Your Family

When a school’s internal systems are breached, the people most exposed are the families who entrusted their personal details to that institution. Your child’s full name, date of birth, address, parent contact information, and possibly medical or academic notes could sit inside those files. Even without exact record counts, the exposure creates long-term risk because schools rarely delete old records. A breach today can surface your family’s information years from now when criminals combine it with newer leaks.

Parents and staff should treat this incident as a direct compromise of their household data. The fact that the attacker chose to list the school publicly signals they are prepared to release or sell the material if demands are not met.

Doxxing and Identity-Chain Risks

School databases frequently link a child’s identity to both parents’ names, home address, phone numbers, and email accounts. Once criminals obtain that core information, they can map it to social-media handles, gaming usernames, and other online footprints. This creates an identity chain that turns a single breach into repeated targeting. A stolen student email can lead to school-portal takeovers, while a parent’s phone number can be used for SIM-swapping or phishing calls that sound legitimate because the caller already knows family specifics.

Credential leaks of this nature also cascade into gaming accounts. Children often reuse school-related passwords or email addresses for Roblox, Minecraft, Discord, or Steam. Successful account takeover on those platforms can expose chat logs, voice recordings, and location data that further enrich a doxxing profile.

RansomHub’s Known Track Record

Public reporting attributes the emergence of RansomHub to early 2024. The group has quickly built a reputation for aggressive double-extortion tactics: encrypting victim systems while simultaneously exfiltrating data for later public release. Notable prior victims include healthcare providers, municipal governments, and private educational institutions. Their typical playbook begins with initial access gained through compromised credentials or vulnerable remote-desktop services, followed by lateral movement inside the network, data theft, and finally deployment of ransomware. If payment is refused, they publish samples or the full archive on their leak site to pressure the victim and embarrass them publicly.

The group’s rapid rise and willingness to target schools suggest they view educational organizations as soft targets that often lack enterprise-grade defenses yet hold sensitive family information.

What to do

  • Run a DoxxScan to map every link between your family’s emails, phone numbers, gaming handles, and real-world identities so you can see the full exposure chain created by this claimed breach.
  • Rotate any password used at donbosco-landser.net or related school services anywhere it has been reused, and immediately enable 2FA through an authenticator app rather than SMS.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your family’s data appears it is caught and acted upon within hours.
  • Cover the entire household with DoxxScan family protection, which extends to dependents and children’s gaming accounts that often chain back to the same leaked school records.
  • Let DoxxScan remediation specialists manage takedown requests for any exposed personal documents or broker listings that surface from this incident.

The breach of donbosco-landser.net illustrates how quickly a school ransomware incident becomes a permanent family privacy problem. Acting early limits how far attackers can travel down the identity chain. Start your DoxxScan trial today for continuous monitoring, AI-powered identity-chain mapping, and hands-on remediation by specialists that covers your whole household, including children’s gaming accounts.

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.
