Abel Schillinger Listed by anubis Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On February 8, 2026, the Abel Schillinger organization was listed by the anubis ransomware group. The listing states that internal files were exfiltrated during a ransomware attack, with references to drafts and intellectual property. Public information on the number of individuals affected or the precise volume of data remains undisclosed. This incident occurs amid continued ransomware activity directed at professional services firms that handle sensitive client materials. Such listings on threat-actor sites often signal that data has left the organization's control, even when ransom demands are not met or details are not immediately confirmed by the victim.

Inside the incident

The reported event centers on a listing placed by the anubis group on February 8, 2026. The group claims to have obtained internal files from Abel Schillinger through a ransomware operation. No official statements from the organization regarding the timing of the intrusion, the method of access, or the scale of exfiltration have been made public. The number of people whose information may be involved is also not disclosed.

Inside anubis

Anubis is a ransomware operation that has appeared in public reporting for encrypting victim systems and removing copies of data before demanding payment. Groups of this type commonly maintain leak sites where they list organizations and, in some cases, publish samples or full archives when negotiations fail. The listing of Abel Schillinger constitutes the group's claim; independent confirmation of the data's contents or the circumstances of its removal has not been provided in available records.

Who is Abel Schillinger?

Abel Schillinger operates as a patent law practice. Organizations in this sector routinely receive, draft, and store documents that describe inventions, technical specifications, and prosecution strategies on behalf of clients. These materials often include unpublished technical details that have commercial value prior to patent grant or while applications remain pending. A breach affecting such a firm therefore touches both the firm's own records and the intellectual-property interests of its clients across multiple industries.

What was likely exposed

The listing describes internal files exfiltrated in a ransomware attack, with explicit mention of drafts and intellectual property. No further inventory of file types, client names, or specific data fields has been released. Patent-law practices typically hold correspondence with patent offices, invention disclosures, prior-art searches, and draft applications; however, the exact contents removed in this case remain unconfirmed beyond the general description provided in the claim.

What's at stake

For individuals and organizations whose patent-related materials may be involved, exposure carries the possibility that technical or strategic information could circulate beyond intended recipients. This can affect ongoing or future patent filings, competitive positioning, and confidentiality obligations owed to clients. For the firm itself, the incident adds operational, legal, and reputational considerations common to any professional-services breach involving client data.

If your data was in this claimed breach

Individuals concerned about possible exposure should monitor official communications from Abel Schillinger and any notifications required under applicable data-protection rules. Practical first steps include changing passwords for any accounts linked to the firm, enabling multi-factor authentication, and reviewing recent account activity for unusual access.
