Norgeshus Listed by Sarcoma Ransomware Group

On June 4, 2025, Norwegian homebuilder Norgeshus appeared on the leak site of the sarcoma ransomware group in a listing claiming internal files were exfiltrated during a ransomware attack.

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 580 companies.

Reported Details of the Incident

Public reporting indicates that sarcoma posted Norgeshus to its data-leak portal, claiming to have stolen company files. The exact number of people whose information was taken remains unknown. Available reporting describes the exposed material as internal documents rather than a structured database of customer records. No specific deadline for ransom payment has been publicly confirmed in connection with this listing.

The breach follows the pattern of many ransomware incidents in which attackers first encrypt systems and then threaten to publish stolen data if payment is not made. Norgeshus is a builder that works directly with families designing and constructing homes, which means the compromised files could contain contracts, correspondence, or personal details provided by customers during the building process.

Why This Matters for You and Your Family

When a company that handles your home-building project suffers a breach, your personal information can end up in the hands of criminals. Internal files often include names, addresses, phone numbers, email accounts, payment details, and sometimes copies of identification documents. Once that information leaves the company’s control, it can be sold, traded, or used to target you directly.

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.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
