Everything online is hackable. This is true for Equifax's data and the federal Office of Personal Management's data, which was hacked in 2015. If information is on a computer connected to the internet, it is vulnerable.

But just because everything is hackable doesn't mean everything will be hacked.

On January 3, the world learned about a series of major security vulnerabilities in modern microprocessors. Called Spectre and Meltdown, these vulnerabilities were discovered by several different researchers last summer, disclosed to the microprocessors' manufacturers, and patched—at least to the extent possible.

This news isn't really any different from the usual endless stream of security vulnerabilities and patches, but it's also a harbinger of the sorts of security problems we're going to be seeing in the coming years. These are vulnerabilities in computer hardware, not software.

The security of pretty much every computer on the planet has just gotten a lot worse, and the only real solution—which,of course, is not a solution—is to throw them all away and buy new ones that may be available in a few years.

On Wednesday, researchers announced a series of major security vulnerabilities in the microprocessors at the heart of the world's computers for the past 15 to 20 years. They've been named Spectre and Meltdown, and they operate by manipulating different ways processors optimize performance by rearranging the order of instructions or performing different instructions in parallel. An attacker who controls one process on a system can use the vulnerabilities to steal secrets from elsewhere on the computer.
