NSM Insurance Group Listed by hive Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The NSM Insurance Group Listed by hive Ransomware Group (reported March 18, 2022) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
On March 18, 2022, the ransomware group known as hive listed NSM Insurance Group on its data-leak site. The listing states that internal files were taken during a ransomware incident, though the number of records, the precise contents of those files, and whether any data was later published remain undisclosed.
The event is one of many similar claims made by ransomware operators against organisations in the insurance sector. Its significance lies in the nature of the data such firms routinely hold and the limited public information released about the scope of this particular incident.
What happened
NSM Insurance Group appeared on the hive ransomware group’s leak site on 18 March 2022. The group claims to have exfiltrated internal files during a ransomware attack. No figure for the volume of data or the number of individuals affected has been made public, and it is not confirmed whether the files were subsequently released.
Who is hive?
Hive is a ransomware operation that emerged in 2021 and employs a double-extortion model: it encrypts systems and also removes copies of data, threatening public disclosure if a ransom is not paid. The group has been linked to attacks on entities across multiple countries and industries. Its leak sites function as a pressure tactic, listing victims and, in some cases, posting samples or full archives when negotiations fail.
About NSM Insurance Group
NSM Insurance Group operates as a managing general agent and specialty insurance provider. Organisations of this type underwrite policies, process claims, and maintain records that commonly include customer identification details, policy information, claims histories, and, in some cases, financial or medical data required for underwriting. A breach at such a firm therefore touches both corporate records and information belonging to policyholders and claimants.
What was likely exposed
The only detail released is that internal files were taken. The exact categories of data contained in those files have not been disclosed. Insurance organisations routinely store personal identifiers, contact information, policy numbers, claims documentation, and payment records; however, whether any of these specific data types were present in the exfiltrated material remains unconfirmed.
Why it matters
Insurance records can be used for identity fraud, targeted scams, or the filing of false claims. For the organisation, the incident raises the possibility of regulatory scrutiny and operational disruption. Because the scale of the data removal is unknown, the practical consequences for any individual policyholder or employee cannot yet be quantified from public sources.
If your data was in this claimed breach
Individuals who believe their information may have been involved should monitor account statements and insurance communications for unusual activity. Standard protective steps include placing credit freezes or fraud alerts with major credit bureaus and using unique passwords with multi-factor authentication on any associated online accounts. Readers may also run a free exposure scan of their email address against known breach data to check for prior appearances in public listings.

Publicly posted by hive — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
