Metropolitan Adjustment Bureau Listed by chaos Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

In the current ransomware landscape, groups continue to target organizations holding sensitive operational and client records, often publicizing claims of access on dedicated leak sites. On November 13, 2025, the chaos ransomware group listed Metropolitan Adjustment Bureau, stating that internal files had been exfiltrated during an attack. The number of individuals affected remains unknown, and no further details on the volume or specific contents of the data have been released publicly.

The incident underscores the exposure risks faced by firms that manage insurance-related documentation, where even limited confirmation of exfiltration can raise questions about downstream handling of client information.

Breaking down the breach

The only confirmed public information is the listing itself and the assertion that internal files were taken. No timeline for the intrusion, no count of affected records, and no description of the encryption or exfiltration methods have been disclosed. The organization has not issued a separate statement confirming or refuting the claims at the time of reporting.

Inside chaos

Chaos operates as a ransomware group that lists victim organizations on its leak site after claiming to have encrypted systems and removed data. Such groups typically follow a pattern of initial network access, data collection, deployment of ransomware, and then public pressure through site postings when ransom demands are not met. The listing of Metropolitan Adjustment Bureau constitutes the group’s claim of involvement; independent verification of the underlying access has not been provided in available reporting.

About Metropolitan Adjustment Bureau

Metropolitan Adjustment Bureau is a public insurance adjusting firm that has operated for more than fifty years. Its work centers on assisting homeowners and businesses with claims arising from fire, water, earthquake, and other disaster damage.

What was likely exposed

The facts released to date state only that internal files were exfiltrated. The precise categories of data contained in those files have not been disclosed. Firms of this type commonly store claim forms, adjuster notes, policy numbers, property addresses, and correspondence with insurers and claimants, yet the exact composition of the exfiltrated material remains unconfirmed.

The real-world impact

Individuals whose information appears in insurance adjusting files may face risks of targeted fraud or misuse of personal identifiers if the material circulates. For the organization, the incident can produce operational disruption, added costs for investigation and remediation, and potential regulatory scrutiny depending on the jurisdictions involved. Without Reported Details on data volume or sensitivity, the scale of these effects cannot be quantified from public sources.

What to do if you're exposed

Review recent statements or notifications from Metropolitan Adjustment Bureau or your insurer for any specific guidance. Monitor bank and insurance accounts for unusual activity, place fraud alerts with credit bureaus if personal identifiers are suspected to be involved, and consider enabling multi-factor authentication on accounts linked to the affected policies.
