SonicWall Urges Credential Resets After Security Breach
On September 19, 2025, SonicWall warned customers to reset all firewall-related credentials following a security breach. Attackers accessed less than 5% of its firewall backup files through brute-force attacks on its cloud API service. Although the stolen files contained encrypted passwords, they also held information that could facilitate the exploitation of affected firewalls. Later, it was confirmed that all cloud backups were compromised.
