What the KRACK Wi-Fi vulnerability means for you and your devices

Mashable 

So it turns out your Wi-Fi is vulnerable to hackers. A newly released research paper dropped a pretty sizable security bomb: The security protocol protecting most Wi-Fi devices can essentially be bypassed, potentially allowing an attacker to intercept every password, credit-card number, or super-secret cat pic you send over the airwaves. So what, if anything, can you do about all this -- other than go back to the Ethernet cable-laden Dark Ages? First, let's take stock of just how bad things are. Researcher Mathy Vanhoef, who discovered the vulnerability, explains that it allows for an attack that "works against all modern protected Wi-Fi networks."
