CNSS Benin Email Archive Leaked on DarkForums

Overview

On 26 April 2026, a DarkForums user published an archive described as the email inbox of the Caisse Nationale de Sécurité Sociale (CNSS) of Benin. The post claims the files were extracted directly from the institution's mail server the same day. The archive weighs 5.86 GB and was shared free of charge.

What was published

The poster states the archive contains 5,993 confidential emails and 9,019 attachments. The contents listed in the post include:

• Demande_de_numero_d'immatriculation (registration number requests)
• Réclamation_de_mes_allocations_familiales (family allowance claims)
• Certificat_de_vie_du_consulat_et_carte_de_pension (consulate life certificates and pension cards)
• Annonce_de_décès (death announcements)

The download package is a compressed folder with an emails.json file described as containing 364,693 lines, plus an emails.csv export. A session ID and the poster's X (Twitter) account were provided for contact.

Risks for affected individuals

• Pension and family allowance claims contain personal identifiers and family details that can enable fraud.
• Life certificates and death announcements expose sensitive administrative records of beneficiaries.
• Emails may include identity documents submitted by citizens during registration.

What remains unknown

• The number of citizens whose personal data appears in the correspondence.
• Whether the server breach also affected internal CNSS applications beyond email.
• The full content of the attachments, which the post only partially lists.

What affected people should do

Beninese citizens who interact with CNSS should monitor their pension and allowance files for anomalies, be alert to phishing messages referencing CNSS procedures, and report any suspicious contact to the institution's official channels.
