At least three billion computer chips are vulnerable to a security flaw found this week
Tech companies are still working overtime on patching two critical vulnerabilities in computer chips that were revealed this week. The flaws, dubbed “Meltdown” and “Spectre,” could let hackers get hold of passwords, encryption keys, and other sensitive information from a computer’s core memory via malicious apps running on devices. How many chips are affected? The number is something of a moving target.
