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.

What Public Reporting Shows

Public reporting indicates that qilin listed Castles Technology UK & Ireland on its data-leak portal and claimed to have stolen internal documents. The listing appeared on February 11, 2026. Available details describe the exposed material as internal files; specific record counts or categories of personal data have not been publicly detailed. The incident follows the typical ransomware pattern of encryption followed by threats to publish stolen data if demands are not met.

Why This Matters for You and Your Family

When a payment-technology provider loses control of internal files, the information inside can include customer records, partner contracts, employee details, or transaction logs. If your name, address, email, phone number, or payment history was stored in those systems, it may now sit on a dark-web leak site. That data does not expire. Criminals can reuse it months or years later to open accounts in your name, file fraudulent tax returns, or combine it with other leaks to build a complete profile of your household.

Children are not spared. Many families link children’s school records, gaming logins, or family-shared emails to the same addresses and phone numbers used in adult transactions. A single breach can therefore expose the entire household.

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.
