This week’s reporting on the alleged Everest ransomware breach of ASRock Rack should be a wake-up call for anyone relying on modern server, storage, and cloud hardware. When an enterprise vendor’s internal repositories of firmware, BIOS, BMC code, diagnostic tools, and drivers are exposed, supply chain integrity is in jeopardy.  Adversaries gain insight into board layouts, update mechanisms, and secure boot flows, which accelerates vulnerability discovery and makes it easier to craft implants that look “authentic”. Implants come in many shapes and forms,s including repackaged drivers, UEFI images, and recovery media. In the worst case, compromise at this level undermines the hardware root of trust itself: if attackers can subvert firmware signing, update channels, or UEFI components, they can persist below the operating system, survive reimaging, and silently bypass many controls. Incidents like this underscore that supply-chain attacks targeting firmware and UEFI are now strategic targets, not edge cases. Defenders need to assume that detailed knowledge of platform internals is in adversary hands and respond by monitoring below the OS as a first-class requirement.  Measuring firmware integrity at boot, continuously attesting critical components (UEFI, BMC, NICs, RAID controllers), and watching out-of-band management paths for anomalous behavior is important. The trust model for infrastructure is shifting, and security programs that do not include firmware and UEFI telemetry are already behind the curve. Article: cyberdaily.au/security/13120…
