Mintzer Sarowitz Zeris Ledva & Meyers Listed by SilentRansomGroup Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On December 7, 2025, the ransomware group SilentRansomGroup listed Mintzer Sarowitz Zeris Ledva & Meyers on its leak site, claiming to have exfiltrated internal files during a ransomware attack. The number of individuals affected remains unknown, and the firm has not publicly confirmed the claim or the extent of any data exposure.

Such listings have become a recurring feature of the current threat landscape, where ransomware operators combine file encryption with the threat of data publication to pressure victims. Law firms hold concentrated volumes of sensitive client information, making them consistent targets for groups that monetise stolen records through extortion or resale.

What happened

The only confirmed public detail is the December 7, 2025 listing by SilentRansomGroup. The group asserts that internal files were removed from the firm’s systems. No information has been released about the date of the intrusion, the method of initial access, the volume of data taken, or whether encryption was also deployed. The number of people whose information may be involved is not disclosed.

Inside SilentRansomGroup

SilentRansomGroup is a ransomware operation that follows the double-extortion model now common among such actors. It typically gains access through phishing, compromised remote-access tools or unpatched systems, then exfiltrates data before deploying encryption. The group maintains a leak site where it publishes victim names and sample files to increase pressure on organisations that refuse ransom demands. Its listings are presented by the group as evidence of successful operations, though independent verification of each claim is not always available.

About Mintzer Sarowitz Zeris Ledva & Meyers

Mintzer Sarowitz Zeris Ledva & Meyers, also referenced as Mintzer Sarowitz Zeris & Willis PLLC, is a civil defense law firm operating fourteen offices across six states. Firms of this type routinely manage litigation and advisory work for corporate and insurance clients, which requires the collection and storage of detailed case files, communications, and supporting documentation. Because legal matters often involve personal, financial and medical information belonging to third parties, the compromise of such an organisation can expose data that extends well beyond the firm’s own records.

What data was at risk

The listing refers only to “internal files exfiltrated.” The precise categories of information contained in those files have not been disclosed. Organisations of this kind commonly hold client contact details, litigation documents, discovery materials, insurance records and correspondence that can include personal identifiers. Without a confirmed inventory, it is not possible to state which specific data elements were taken.

The real-world impact

Exposed legal files can contain information that remains relevant for years, increasing the window during which affected individuals may face misuse such as identity theft, targeted fraud or reputational harm. For the firm, the incident adds operational costs related to investigation, notification and potential regulatory scrutiny. Clients whose matters were handled by the firm may also experience secondary effects if their confidential legal information circulates beyond intended recipients.

If your data was in this claimed breach

Individuals who have been clients of the firm or whose information appears in its matters should monitor their financial accounts and credit reports for unusual activity. Enabling multi-factor authentication on important services and using unique passwords reduce the value of any exposed credentials. A free exposure scan of an email address against known breach data can indicate whether the address has appeared in previously published datasets, providing one starting point for further checks.
