fhw-neukoelln.de Listed by DragonForce Ransomware Group

If you are a customer of fhw-neukoelln.de, here’s what is being claimed, and what it would mean for you.

Fernheizwerk Neukölln provides heat to homes in the Berlin-Neukölln district. This local heating company generates and supplies heat to approximately 40,000 homes, ensuring a comfortable temperature during the cold months. They make every effort to provide reliable heat to the community by connecting homes to efficient heating systems throughout the district.
— from DragonForce’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.

fhw-neukoelln.de Listed by DragonForce Ransomware Group

On March 20, 2026, the German district heating provider Fernheizwerk Neukölln appeared on the leak site of the dragonforce ransomware group. The company supplies heat to roughly 40,000 homes in Berlin-Neukölln, and attackers claim to have exfiltrated internal files during a ransomware incident.

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.

What Public Reporting Shows

Public reporting indicates that Fernheizwerk Neukölln’s internal documents were posted on the dragonforce leak site. The heating utility, which operates district heating networks across one of Berlin’s largest residential areas, confirmed it had been targeted. Available reporting describes the data as internal files, though the precise volume and full list of contents remain unclear. No customer names, addresses, or payment details have been publicly enumerated in the initial leak announcement.

The incident follows the group’s typical pattern of encrypting systems and then publishing samples of stolen data when ransom demands are not met. As of the publication date on the leak site, the files were made available for download to other threat actors and researchers.

Why This Matters for You and Your Family

When a local utility that heats 40,000 homes loses control of internal files, the ripple effects reach the families who depend on it. Billing records, maintenance logs, service contracts, and correspondence often contain names, addresses, phone numbers, and account references. Once that information leaves the company’s protected systems, it can appear in unexpected places online.

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.
