Corinthian Media Listed by Akira Ransomware Group

On June 6, 2025, the Akira ransomware group listed Corinthian Media on its leak site and announced it was prepared to publish more than 7 GB of the company’s internal files. The exposed material includes detailed financial data, credit card scans, personal document scans, medical information, and NDAs. Corinthian Media, a media buying and planning firm, has not publicly confirmed the claim, and the exact number of individuals whose records were taken remains unknown.

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 the Akira group first added Corinthian Media to its data-leak portal on June 6, 2025. The actors claim to have exfiltrated more than 7 GB of corporate documents before encrypting systems or disrupting operations. The posted description explicitly lists credit card scans, personal documents, medical information, and NDAs among the stolen files. No sample data has been released so far, and the group has set no public deadline for publication in the available screenshots.

Why This Matters for You and Your Family

When a company that handles advertising campaigns, vendor contracts, or client campaigns suffers a breach, the personal information it stores can belong to everyday customers, employees, and their families. Credit card scans and medical information are particularly damaging because they can be used for identity theft, fraudulent loans, or insurance fraud. If your data was among the records, you may not learn about it for weeks or months. In the meantime, thieves can open accounts, file false tax returns, or sell your details on underground forums.

Children’s records are not immune. Many families share email addresses or phone numbers across household accounts, creating a single point of failure that reaches school forms, sports registrations, and gaming profiles.

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.
