ds-granit.fr Listed by Threeam Ransomware Group

On November 22, 2023, French interior-design firm DS Granit appeared on the leak site operated by the threeam ransomware group. The listing states that internal files were exfiltrated during a ransomware attack; the exact number of records affected and the full scope of data remain undisclosed by both the attackers and the company.

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.

Primary Disclosure Details

The threeam leak site lists DS Granit as a victim and claims the company’s internal files were stolen prior to encryption. No specific volume of data, list of file types, or sample documents is shown in the public portion of the posting. The disclosure does not state whether customer records, employee personal information, or only internal operational files were taken. As of the publication date, DS Granit had not released its own public notification detailing the incident or the categories of information involved.

Why This Matters for You and Your Family

When a company that handles design projects, supplier contracts, and client communications is breached, the information stolen can easily include names, addresses, phone numbers, email accounts, and payment details belonging to ordinary customers. If you or your family have worked with DS Granit or similar French design and renovation businesses, your contact information may now sit in an attacker-controlled archive. Internal files exfiltrated in these incidents frequently contain spreadsheets that link personal details to project addresses, making it simpler for criminals to target households with phishing, identity theft, or physical scams.

Doxxing and Identity-Chain Risks

Stolen internal files often contain more than isolated records; they create chains that link email addresses, phone numbers, physical addresses, and sometimes spouse or child names. Once criminals possess these connections, they can pivot to gaming platforms, social-media accounts, or school portals that reuse the same credentials. A single leaked work email can expose your child’s Roblox or Fortnite account if the same password appears anywhere in the household. These identity chains accelerate doxxing by letting attackers map one piece of information to many others within hours rather than months.

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.
