Vendor cloud backups create systemic risk

Updated: 2025.12.01 4D ago 4 sources
SonicWall says attackers stole all customers’ cloud‑stored firewall configuration backups, contradicting an earlier 'under 5%' claim. Even with encryption, leaked configs expose network maps, credentials, certificates, and policies that enable targeted intrusions. Centralizing such data with a single vendor turns a breach into a fleet‑wide vulnerability. — It reframes cybersecurity from device hardening to supply‑chain and key‑management choices, pushing for zero‑knowledge designs and limits on vendor‑hosted sensitive backups.
