Severe flaw in WPA2 protocol leaves Wi-Fi traffic open to eavesdropping
Severe flaw in WPA2 protocol leaves Wi-Fi traffic open to eavesdropping The proof-of-concept exploit is called KRACK, short for Key Reinstallation Attacks.
It works by exploiting a four-way handshake that's used to establish a key for encrypting traffic. During the third step, the key can be resent multiple times. When it's resent in certain ways, a cryptographic nonce can be reused in a way that completely undermines the encryption.
