A security researcher’s recent proof of a BIOS firmware attack has many readers concerned about the future of firmware attacks. Almost every electronic device today has a rewritable firmware chip. Most malicious tasks — stealing money, passwords, or identities — can more easily be accomplished using normal software-only malware. It’s easier to “brick” (make unusable or unbootable) a computer device with a firmware attack because the attacker just needs to corrupt the firmware code. To protect yourself, buy hardware with built-in protections against malicious firmware modification.”]
