There's a branch of hacking and computer security you don't hear about much, but it's incredibly important. It's called "side-channel attacks."

At its most basic, a side-channel attack is one that lets a hacker get information from a computer using some seemingly insignificant detail of how a computer works. For example, a hacker might measure fluctuations in the processor voltage to figure out what information is being processed, or pick up faint voltage spikes from your keyboard to know what letters you're typing. It sounds like a Hollywood spy thriller, but it's real.

What keeps side-channel attacks from being a worry for everyone is that most attacks against computer hardware require the hacker to be in the same general area, if not actually touching the computer. So they're usually used against major companies or secure government systems.

However, security researchers have found a scary new side-channel attack that could be a game changer. That's because all it takes to work is you visiting the wrong site. Once you do that, a hacker can know everything you're doing on your computer.
