A major security flaw has been discovered in Wi-Fi and we’re all at risk.

Researchers discovered the weakness in WPA2, the protocol that secures all modern Wi-Fi networks. Any modern device with a wireless connection could be open to a KRACK attack that would expose information like credit card numbers, passwords, messages and more.
