Attacking And Defending Bios -

Treat motherboard firmware updates with the same urgency as OS security patches.

Modern OS features use the CPU's virtualization extensions to protect critical memory from compromised firmware. 🔮 The Evolving Threat Landscape

If an attacker has physical access to the machine, they can bypass digital security controls. Attacking and Defending BIOS

Modern systems employ automated defenses to detect and repair firmware corruption.

System Management Mode (SMM) is a highly privileged CPU mode. Vulnerabilities in SMM handlers allow attackers to execute arbitrary code with ring -2 privileges. Treat motherboard firmware updates with the same urgency

A UEFI feature that ensures only cryptographically signed, trusted bootloaders and drivers can execute during the boot process.

Attackers do not always need physical access. They can leverage vulnerabilities from within a compromised operating system. Modern systems employ automated defenses to detect and

Quick physical tampering of unattended devices to install malicious hardware or modify firmware. 2. Remote and Software-Based Exploitation
