THE MILLENNIUM GROUP Listed by D4rk4rmy Ransomware Group

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

The Millennium Group was listed on D4rk4rmy's leak site. D4rk4rmy claims to have stolen internal data. This is the group's claim, not a confirmed finding.

THE MILLENNIUM GROUP Listed by D4rk4rmy Ransomware Group

On August 16, 2025, the ransomware group d4rk4rmy added The Millennium Group to its leak site and began publishing what it claims are the company’s internal files. The Millennium Group, a global document management and workplace services provider operating for more than 40 years, serves both corporate and government clients. Any customer or employee whose personal or business records were stored in TMG’s systems may now have their data exposed.

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 d4rk4rmy exfiltrated internal files during a ransomware attack on TMG’s network. The group listed the company on its dark-web leak page and has started releasing samples of the stolen data. The exact number of people affected remains unknown, and the full volume of records has not been disclosed. Available reporting describes the exposed material as internal files rather than a structured database of customer records, though such files frequently contain names, addresses, contact details, contract information, and scanned documents.

August 16, 2025 marks the date the listing appeared. No ransom deadline has been publicly confirmed in the initial reports, but ransomware groups routinely set short windows before releasing larger batches of data.

Why This Matters for You and Your Family

When a service provider like TMG is breached, the information at risk often belongs to ordinary customers who used its document management or workplace services. If your employer, your child’s school, your medical provider, or your local government contracted with TMG, records containing your name, address, phone number, email, or identification numbers may have been taken. Once posted on a ransomware leak site, that information can be downloaded by anyone and combined with data from earlier breaches.

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.
