Marquis Accuses SonicWall of Security Lapses; Ties it to Ransomware Attack

Marquis has sued SonicWall in the U.S. District Court for the Eastern District of Texas, alleging that a 2025 breach of SonicWall’s cloud backup service exposed firewall configuration backups and enabled a ransomware attack on Marquis’ network. The complaint says stolen emergency “scratch codes” and other configuration data allowed attackers to bypass defenses and steal sensitive PII, and Marquis seeks a jury trial. #Marquis #SonicWall
