On April 19, 2025, the Danish vocational education provider EUC Sjælland appeared on the leak site of the ransomware group RansomHouse. The organization, which serves thousands of students and staff across four campuses in Næstved, Køge, Haslev and Greve, is claimed to have had internal files exfiltrated during a ransomware attack.

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 580 companies.

Reported Details of the Breach
Public reporting indicates that EUC Sjælland, originally formed in 1999 through the merger of technical schools in Køge, Haslev and Næstved, was listed by the group on its dark-web portal. The data consists of internal files that the attackers claim to have taken before encrypting systems. No precise victim count has been released, and the exact volume or specific types of records remain unconfirmed in available reporting. The listing appeared on the RansomHouse leak site, accessible via the onion address tracked by ransomware.live.
Why This Matters for You and Your Family
When a school or training centre is breached, the information exposed often includes personal details of students, parents, employees and contractors. Internal files can contain names, addresses, dates of birth, national identification numbers, contact information, employment records and sometimes family-related data. If your child attends or has attended EUC Sjælland, or if you or a family member work there, your information may now sit in a criminal archive. Once stolen, such data rarely disappears. It can be sold, traded or used months or years later to commit identity theft, fraud or harassment.
The Doxxing and Identity-Chain Risks
Ransomware incidents like this frequently cascade into doxxing. Attackers or buyers of the data can link an email address from the leak to gaming usernames, social-media handles and phone numbers. A single school record can expose a child’s full name and birthdate, which is then matched to a Roblox or Discord account using the same password. That connection turns a simple breach into a chain that reveals home addresses, family relationships and daily routines. Credential leaks of this nature have repeatedly led to account takeovers on gaming platforms, followed by demands for ransom or public shaming. Protecting both adult and children’s accounts is therefore essential.
