Cathar Games Listed by avaddon Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Cathar Games Listed by avaddon Ransomware Group (reported September 9, 2021) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
Inside the incident
The only confirmed information is the listing itself. Avaddon posted Cathar Games on its site and asserted that internal data had been removed. No independent confirmation of the theft or the contents of the files has been reported. The scale of the operation, including how many systems were affected or how the initial access occurred, remains undisclosed.
The group behind it: avaddon
Avaddon operated as a ransomware group that combined file encryption with the threat of data publication. The group maintained a leak site where it listed organisations that had not met its demands. This double-extortion approach was documented across multiple incidents involving companies in different sectors. The listing of Cathar Games follows the pattern the group used with other claimed victims, though the accuracy of any individual claim requires separate verification.
About Cathar Games
Cathar Games is a video-game development and publishing organisation. Companies in this sector routinely store customer account details, transaction records, and internal project information. A successful intrusion that reaches internal files can therefore touch both operational materials and records that identify individual users or partners.
What data was at risk
The listing refers only to internal files. No inventory of specific data types has been released. Organisations of this kind commonly hold email addresses, usernames, payment information, and correspondence; however, whether any of these categories were among the exfiltrated material is unconfirmed.
The real-world impact
Individuals whose details appear in stolen internal files may face increased risk of phishing, account takeover attempts, or misuse of personal information. For the company, the incident adds operational disruption from any encryption that occurred and potential loss of control over proprietary documents. The absence of Reported Details about the data limits precise assessment of downstream effects.
What to do if you're exposed
Anyone who has an account with Cathar Games or who has shared personal information with the company should monitor those accounts and associated email addresses for unusual activity. Changing passwords, enabling multi-factor authentication, and reviewing financial statements for unauthorised transactions are standard first steps. Readers can also run a free exposure scan of their email address against known breach data to check for prior appearances in public listings.

Publicly posted by avaddon — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
