CAS EXhibition Partners Listed by Lynx Ransomware Group

If you are a customer of CAS EXhibition Partners, here’s what is being claimed, and what it would mean for you.

CAS EXhibition Partners was listed on Lynx's leak site. Lynx claims to have stolen internal data. This is the group's claim, not a confirmed finding.

CAS EXhibition Partners Listed by Lynx Ransomware Group

On September 15, 2025, the lynx Ransomware Group added Cas Exhibition Partners to its leak site, claiming that internal files had been exfiltrated from the company during a ransomware attack. Anyone whose information appears in those files—including customers, vendors, or employees—now faces the possibility that sensitive business and personal data has been published or sold on criminal forums.

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 Cas Exhibition Partners suffered a ransomware intrusion in which attackers gained access to internal systems and removed files before encrypting data. The lynx leak site listed the victim on September 15, 2025, and began publishing samples of the stolen material. Available reporting describes the exposed information as internal files; exact volume and full contents remain unconfirmed by the company. No official statement detailing the breach timeline or specific data types has been released to the public.

Why This Matters for You and Your Family

When a company that handles event registrations, vendor contracts, or client bookings is breached, the information it stores often includes names, addresses, phone numbers, email accounts, and payment details belonging to ordinary people. If you or your family have attended exhibitions, booked stands, or worked with Cas Exhibition Partners, your data may now be circulating among criminals. Credential leaks from such incidents frequently cascade into account takeovers on other services where the same email and password are reused.

Children’s information is not immune. Gaming accounts, school activity sign-ups, or family event registrations handled through exhibition partners can link back to household addresses and parent emails, creating long-term exposure.

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.
