Chip Backdoors: Assessing the Threat
By Jeff Goldman - 04 Aug, 2022 - Comments: 0

In 2018, Bloomberg Businessweek made an explosive claim: Chinese spies had implanted backdoors in motherboards used by some high-profile customers, including the U.S. Department of Defense. All of those customers issued strongly worded denials. Most reports of hardware backdoors have ended up in exchanges like these. There are allegations and counter-allegations about specifics. But as hardw... » read more
