arc-reins.com + fidelityunited.ae UPDATE-FULL DATA DUMP Listed by stormous Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
A data breach involving ARC was disclosed on May 11, 2026, after the stormous Ransomware Group listed arc-reins.com and fidelityunited.ae in a full data dump of internal files. Individuals connected to the affected organisations are advised to review their exposure and take appropriate protective steps.
What happened
The incident is described as a ransomware attack that resulted in the exfiltration of internal files from ARC. The group placed the organization on its leak site on May 11, 2026. No independent confirmation of the attack date, data volume, or method of initial access has been made public.
The group behind it: stormous
Stormous is a ransomware group that publishes victim names and claimed data samples on a dedicated leak site after encrypting systems or stealing files. The group typically targets organizations across multiple sectors and uses these listings to pressure victims. In this case, the group claims responsibility for the ARC incident through its listing, though the accuracy of the posted details has not been verified by outside sources.
ARC and its sector
ARC works in the reinsurance and insurance sector, with operations that include marine, property, and liability coverage, particularly in the Middle East. Organizations of this type routinely maintain records on clients, partners, employees, and regulatory compliance. A breach in this sector can affect both commercial operations and individuals whose personal information is held for contractual or verification purposes.
What data was at risk
The only confirmed detail is that internal files were allegedly exfiltrated. The group claims the material includes compliance audit data, bank details, legal licenses, tax documents, contracts, KYC files, employee personal records, and insurance archives. The precise contents and whether all listed items were obtained cannot be confirmed from available information.
- Compliance audit data, bank details, and tax documents
- Employee passports, ID cards, emails, and contracts
- Marine, property, and liability insurance records
Why it matters
Release of employee identity documents and contract details can enable targeted fraud or impersonation. Commercial records such as bank details and insurance archives may be used for financial or competitive purposes. The organization faces potential regulatory questions and the need to notify affected parties once the scope is clarified.
What to do if you're exposed
Individuals who believe their information may be involved should review bank and insurance statements for anomalies and place fraud alerts with credit agencies where available. Readers can run a free exposure scan of their email to check whether their information has surfaced in known breach data. Organizations should follow standard incident response procedures and consult legal counsel regarding notification obligations.

Publicly posted by stormous — 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.
