BMC Holes Let Attackers Live Beneath the OS, Past Every Endpoint Tool
Your servers' Baseboard Management Controllers run outside the OS, and that's exactly the problem. Researchers warn that flaws in BMC firmware and the aging IPMI protocol let attackers take control below the operating system, surviving reinstallations and ordinary recovery. Standard EDR and antivirus sit above this layer, so a compromised BMC is invisible to the very tools meant to catch it. For GPU clouds and bare-metal fleets with thousands of hosts on shared management networks, one foothold can reach far beyond a single box.
