During Sunday's 60 Minutes white-wash of the NSA, Debora Plunkett, director of cyber defense for the NSA, claims they "stopped" a nation-state cyber attack that would brick computers across the country through a fake BIOS update. She claims the NSA "stopped" this attack by "working with computer manufacturers to close the vulnerability." Sounds like FUD to me.
