gymund.dk Listed by lockbit2 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The gymund.dk Listed by lockbit2 Ransomware Group (reported May 19, 2022) 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.
What happened
The only confirmed public record is the May 19, 2022 listing of gymund.dk on the LockBit2 leak site. The group claims to have stolen internal data. No information has been released about the timing or method of the intrusion, the volume of data taken, or whether any files were subsequently published.
Who is lockbit2?
LockBit2, also known as LockBit, is a ransomware-as-a-service operation that has been active since at least 2019. The group supplies encryption tools to affiliates who conduct intrusions, then demands payment for both decryption keys and assurances that stolen data will not be released. It has been linked to incidents across multiple countries and sectors, relying on double-extortion tactics that combine system encryption with threats to publish exfiltrated material.
About gymund.dk
gymund.dk operates as a fitness facility in Denmark. Organizations in this sector routinely collect and store member registration details, contact information, membership histories, and payment records. A breach involving internal files at such an entity can therefore touch both operational documents and personal data belonging to customers and staff.
What was likely exposed
Public reporting states only that internal files were exfiltrated. The exact categories of data involved have not been disclosed. Fitness organizations commonly hold names, addresses, email addresses, telephone numbers, membership identifiers, and financial details associated with payments or direct debits; whether any of these specific elements were present in the claimed theft remains unconfirmed.
Why it matters
Internal files can contain information that enables account takeover, fraud, or unwanted contact if personal or financial records are included. For the organization, the incident may result in costs related to investigation, remediation, and compliance with Danish and European data-protection requirements. Individuals whose information is present in the files face these risks regardless of whether the files are later published.
If your data was in this claimed breach
People who held memberships or accounts with gymund.dk should review their financial statements for unexpected activity and change passwords on any associated services. Enabling multi-factor authentication on email and financial accounts reduces the chance of unauthorized access. Readers can also run a free exposure scan of their email address against known breach records to determine whether their information appears in publicly documented incidents.

Publicly posted by lockbit — 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.
