TMA Group of Companies Listed by Sarcoma Ransomware Group

On April 10, 2025, the TMA Group of Companies in Australia appeared on the leak site of the sarcoma ransomware group after attackers exfiltrated 1.1 TB of internal files. The incident affects anyone whose personal or financial information was stored in TMA’s systems, including customers, visitors, and business partners who interacted with the company’s digital platforms and hardware solutions.

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 sarcoma actors breached TMA Technology, the customer-experience division of the group. The attackers extracted 1.1 TB of internal documents before publishing a sample on their leak portal. No exact victim count has been released, and it remains unclear which specific categories of records were taken. The leak site lists the Australian company under the sarcoma group’s April 10 entry, claiming the data was exfiltrated during a ransomware operation.

Why This Matters for You and Your Family

When a company that handles customer interactions suffers a breach, the information it stores about you can end up in criminal hands. TMA’s solutions connect visitors, partners, and guests, which often means names, contact details, payment records, or account information sit in the same environment that was compromised. If your data was among the 1.1 TB taken, it can be sold, published, or used to launch further attacks against you or members of your household. Ordinary families who simply shopped, booked, or registered through TMA’s platforms now face the same exposure risk as the company’s largest clients.

Credential leaks like this one frequently cascade into account takeovers on unrelated services where the same email and password were reused.

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.
