Miller Johnson Jones Antonisse & White Listed by genesis Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On February 17, 2026, the ransomware group genesis listed Miller Johnson Jones Antonisse & White on its site. The listing states that internal files were exfiltrated during a ransomware attack against the Oklahoma City law firm. The number of individuals whose information may be involved has not been disclosed. The incident is significant because law firms routinely process confidential client records, and any confirmed exfiltration of internal files raises questions about what material may have left the organization.

Inside the incident

The only confirmed public information is the February 17, 2026 listing by genesis and the statement that internal files were taken. No details on the date of the intrusion, the method of access, the volume of data, or any ransom demand have been made public. The firm has not issued a statement confirming or denying the claims, and the total number of people potentially affected remains unknown.

Who is genesis?

Genesis is a ransomware group that maintains a public leak site where it lists organizations it claims to have targeted. The group typically asserts that it has encrypted systems and copied files, then publishes samples or directories to pressure victims. Its listings are unverified claims until corroborated by the affected organization or independent investigation. The group has appeared in multiple prior incidents involving professional-service firms, though each case must be assessed on its own facts.

Who is Miller Johnson Jones Antonisse & White?

Miller Johnson Jones Antonisse & White is a law firm headquartered in Oklahoma City. Law firms of this type maintain client matter files, correspondence, financial records, and internal administrative documents. Because attorneys hold privileged information, any breach that reaches those records can affect both the firm and its clients across multiple matters.

What data was at risk

The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of specific file types or data categories has been released. Organizations in this sector commonly store client names, contact details, case-related documents, billing information, and employee records, but the precise contents of the exfiltrated material have not been confirmed.

What's at stake

For individuals whose information appears in the firm’s files, the main concerns are potential misuse of personal or financial details and the possibility that sensitive legal matters could become public. For the firm itself, the incident may trigger regulatory notifications, client notifications, and costs associated with investigation and remediation. Until more information is released, the scale of these consequences cannot be quantified.

If your data was in this claimed breach

Begin by monitoring accounts for unusual activity and enabling multi-factor authentication where available. Request a copy of any data-breach notice the firm may issue. Individuals can also run a free exposure scan of their email address against known breach datasets to check whether their information has appeared in other incidents.
