SonicWall disclosed that brute-force attacks against the MySonicWall cloud backup portal allowed unauthorized access to a subset of firewall preference files affecting fewer than 5% of installations; sensitive credentials were reportedly strongly encrypted, but encoded configuration details could provide useful intelligence to attackers, and there is no current evidence the files were leaked or that the incident was ransomware-related.
