Hagen Rosskopf Listed by akira Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to target professional services firms that hold large volumes of sensitive personal and legal records. On 16 February 2026 the Akira group listed Hagen Rosskopf on its leak site, stating that internal files had been taken during a ransomware operation and that corporate data would be published soon. No independent confirmation of the volume or contents of any exfiltrated material has been made public, and the number of individuals potentially affected remains unknown.

Inside the incident

The only public record of the event is the listing itself. Akira posted a notice claiming that corporate data would be uploaded and described categories of material it said had been removed. No details on the date or method of intrusion, the duration of access, or the scale of the operation have been released by the firm or by investigators. The firm has not issued a public statement confirming or disputing the claims.

The group behind it: akira

Akira is a ransomware operation that emerged in early 2023 and has since conducted intrusions against organisations in multiple countries. Public reporting indicates the group typically uses double-extortion tactics, encrypting systems and removing copies of data before demanding payment. It maintains a leak site where it lists victims and, in some cases, publishes samples or full archives when negotiations fail. The group’s listings constitute its own assertions; independent verification of the data described in any single incident is often limited or absent.

About Hagen Rosskopf

Hagen Rosskopf is described as a boutique law firm focused on personal-injury cases, with a particular emphasis on claims involving injured cyclists. Law firms of this type routinely receive and store client identification documents, medical records, police reports, court filings and internal correspondence. These records are protected by professional confidentiality obligations and, in many jurisdictions, by data-protection statutes that treat health and identity information as sensitive.

What was likely exposed

The listing states that internal files were taken. Akira claims the material includes clients’ passports, driver’s licences, health information, confidential legal files, court documents, police reports and employee files. The precise contents, file counts and whether any of the material has been published remain undisclosed. Organisations in this sector commonly hold the categories of data named in the listing, but the exact scope of any exfiltration in this case is unconfirmed.

Why it matters

Legal files and health records can contain detailed personal histories that are difficult to change. If such material were to circulate, affected individuals could face risks of identity misuse, unwanted disclosure of medical conditions, or complications in ongoing legal matters. For the firm, the incident adds to the operational and reputational pressures already associated with ransomware events in the legal sector, where client trust and regulatory compliance are central.

Were you affected?

Individuals who are or were clients of Hagen Rosskopf should contact the firm directly for information on any notifications or protective measures being offered. A practical first step for anyone concerned about possible exposure is to monitor official communications from the firm and to review account statements and credit reports for unusual activity.
