SonicWall Urges Password Resets Following Cloud Backup Breach

SonicWall has urged customers to reset passwords after a security breach exposed encrypted firewall configuration backup files for less than 5% of its customers, potentially aiding attackers in exploiting firewalls. The breach involved brute-force attacks on cloud backups, with no evidence of files being leaked online. SonicWall recommends verifying backup status, resetting passwords and TOTP, and importing new preferences. The incident coincides with ongoing attacks by the Akira ransomware group exploiting SonicWall vulnerabilities to gain network access and disable security defenses.
