SonicWall MySonicWall Cloud Backup File Security Incident

SonicWall has disclosed a security incident affecting its MySonicWall cloud backup service. Threat actors conducted brute force attacks on the MySonicWall.com portal and gained unauthorized access to a subset of firewall preference files. While fewer than 5% of firewall installations were impacted and sensitive credentials remain strongly encrypted, configuration details contained in the files were only encoded, potentially providing attackers with useful intelligence for targeting associated firewall devices. According to SonicWall, no evidence currently suggests that the files have been leaked online, and the event was not ransomware-related.
