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 Hunters posted Costex to its dark-web leak portal, showing samples of stolen data. The entry states that internal files were taken and that the victim’s systems were also encrypted. No exact number of affected individuals has been released, and the precise volume or sensitivity of the files remains unclear from the public posting. Available reporting describes the incident as a classic ransomware double-extortion case in which the attacker threatens both operational disruption through encryption and public exposure of the stolen information.

Why This Matters for You and Your Family

When a company like Costex suffers a breach, the information it holds about customers, vendors, and partners often ends up at risk. If you or anyone in your household has done business with the company, your contact details, financial records, or other personal data may now sit on a criminal leak site. Once files leave a corporate network, they can be downloaded by other criminals within hours. That single exposure frequently becomes the first link in a chain that leads to identity theft, account takeovers, or harassment aimed at you and your family.

The Doxxing and Identity-Chain Risk

Stolen corporate files commonly contain spreadsheets that link names, email addresses, phone numbers, and sometimes home addresses. Attackers and subsequent data brokers can combine this information with usernames found in the same documents. The result is an identity chain that reveals how your work email connects to your personal accounts, your children’s gaming handles, and even family photos. Credential leaks like this one regularly cascade into gaming-account takeovers, because the same password or recovery email used at a breached vendor often protects Steam, Roblox, or Discord logins. Public reporting shows these chains frequently end in doxxing, swatting, or extortion attempts against ordinary households.

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.
