Severe WiFi security flaw puts millions of devices at risk

Here’s how it works. Attackers find a vulnerable WPA2 network, then make a carbon copy of it and impersonate the MAC address, then change the WiFi channel. This new, fake network acts as a “man in the middle,” so when a device attempts to connect to the original network, it can be forced to bypass it and connect to the rogue one. Normally, WPA2 encryption requires a unique key to encrypt each
