Burris MacOmber, PLLC, a law firm based in Tucson, Arizona, suffered a ransomware attack announced by the group TheGentlemen on June 20, 2026. The attackers have threatened to release all sensitive legal data if their demands are not met. The firm has not yet issued official breach notification letters to clients. The legal sector is often targeted due to the sensitive nature of information handled.
The types of data exposed include sensitive legal data, client files, case documents, and potentially confidential communications. The exact number of affected individuals has not been officially disclosed, but it is likely limited to the firm's clients. While not explicitly confirmed, it is probable that client identifiers and other sensitive information depending on case types are involved. There is no public record of an Arizona Attorney General filing or class action lawsuits as of June 25, 2026.
Details are emerging, and official notifications may be delayed as the firm addresses the situation. The threat actor's status is listed as "unknown" in ransomware intelligence databases, and no resolution has been confirmed.
