If you are a customer of ams-group.co.uk FULL DATA DUMP 33GB, here’s what is being claimed, and what it would mean for you.

The extracted data comprises administrative and financial records, payroll sheets, and client and partner directories, alongside technical and engineering specifications, employee records, and business plans. It also includes architectural designs, official contracts, detailed engineering reports, and construction site maps, as well as risk assessments, internal correspondence, and tax and legal information.

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 582 companies.

Reported Details of the Breach

Public reporting indicates the data was exfiltrated during a ransomware attack on AMS Group, a UK-based firm involved in architectural and engineering services. The archive contains administrative and financial records, payroll sheets, client and partner directories, employee records, business plans, architectural designs, official contracts, detailed engineering reports, construction site maps, risk assessments, internal correspondence, and tax and legal information.

Available reporting describes the incident as a full data dump rather than a partial leak. The exact number of individuals whose personal information appears in the files remains unknown, but the presence of payroll sheets, employee records, and client directories suggests that current and former staff, as well as business contacts, are likely affected.

Why This Matters for You and Your Family

When a company you work for, do business with, or have your information stored by suffers a breach like this, your personal details can end up freely downloadable by anyone. Employee records and payroll sheets often include addresses, dates of birth, national insurance numbers, bank details, and salary information. Tax and legal files can add even more context that makes identity theft or financial fraud simpler for criminals.

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.
