If you are a customer of fsd.se, here’s what is being claimed, and what it would mean for you.

Sweden’s first private fire consulting company was founded by Dr. Yngve Anderberg in Lund in 1977. In the early years, FSD’s main focus was on research and structural fire protection.The first four employees were hired in 1985. Over time, the bus...

fsd.se Listed by lockbit3 Ransomware Group

On June 01, 2023, Sweden’s private fire-safety consultancy FSD appeared on the LockBit 3.0 ransomware leak site. The listing states that internal files were exfiltrated during a ransomware attack; the number of records affected and the precise data types remain undisclosed by the group.

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 from the Listing

The LockBit 3.0 leak page, still accessible via its onion address at the time of writing, claims successful data theft from FSD and threatens publication unless a ransom is paid. The disclosure indicates that the company’s internal files were taken but provides no count of affected individuals, no sample documents, and no deadline beyond the standard countdown timer used by the gang. Public mirrors hosted on ransomware.live preserve the original post dated June 01, 2023, claiming the incident surfaced through the extortion platform itself rather than a voluntary company notification.

Why This Matters for You and Your Family

When a specialist consultancy like FSD suffers a breach, anyone whose personal or business records passed through its systems faces sudden exposure. Fire-safety reports, building-inspection data, insurance correspondence, and employee or client contact details can easily contain names, addresses, phone numbers, and email accounts. Once those details leave the company’s control, they become raw material for identity thieves, phishing campaigns, and follow-on extortion attempts aimed at you or members of your household. Even if you cannot remember interacting with FSD, the reality of modern consulting means your information may have been shared without your direct knowledge.

The Doxxing and Identity-Chain Risk

Stolen internal files frequently link email addresses, usernames, and phone numbers to real-world identities. Threat actors then cross-reference those artifacts across dark-web markets, paste sites, and public records to build detailed profiles. A single leaked work email can expose your home address, spouse’s name, and children’s school details within hours. Credential leaks like this one cascade into account takeovers, especially for gaming platforms where kids often reuse passwords or recovery addresses tied to a parent’s breached account. The result is a doxxing chain that can lead to harassment, SIM-swapping, or targeted scams against your entire family.

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.
