Fuite de données chez un fournisseur: l’attaque ransomware contre Marquis expose des clients de banques américaines

Selon BankInfoSecurity (article de Mathew J. Schwartz, 31 décembre 2025), plusieurs établissements financiers américains notifient des fuites de données liées à une attaque de ransomware ayant ciblé le fournisseur Marquis Software Solutions, éditeur texan de logiciels de marketing et de conformité pour plus de 700 banques et credit unions. • Nature de l’incident: une attaque de ransomware le 14 août impliquant la compromission d’un pare-feu SonicWall de Marquis. Des enquêteurs externes mandatés par Marquis ont établi que l’attaquant a pu accéder à des fichiers stockés par Marquis pour le compte de ses clients professionnels et que l’incident serait limité à l’environnement de Marquis. Les données potentiellement exposées incluent: noms, adresses, numéros de téléphone, numéros de sécurité sociale (SSN), informations de compte financier sans codes d’accès, et dates de naissance. 🚨

iQ Credit Union has disclosed that a ransomware incident at its vendor, Marquis Software Solutions, exposed personal information of over 111K Washington residents. The attacker accessed files containing names, SSNs, dates of birth, addresses, and partial financial data after exploiting a SonicWall firewall.

Identity protection services are being provided, and individuals are advised to monitor accounts and consider credit freezes.

How should financial institutions rethink vendor-risk strategies moving forward?

GreyNoise reports a coordinated wave of login attempts against Palo Alto GlobalProtect portals, later expanding into scans of SonicWall SonicOS API endpoints. More than 7,000 IPs tied to 3xK GmbH infrastructure were involved.

Palo Alto Networks confirmed the activity represents credential-based probing, not a vulnerability exploit.
Defenders are encouraged to enforce MFA, track recurring client fingerprints, and apply dynamic blocking.
