WPA2 security hole KRACKs Wi-Fi networks wide open
by from Techreport on (#356DB)
The United States Computer Emergency Readiness Team has issued a warning about a new attack that affects Wi-Fi networks using the commonly-used WPA2 protocol. The vulnerability is called a KRACK attack and affects the four-way handshake that occurs between an access point and a client device when the client wants to join the protected network.
Attackers can decrypt packets on WPA2 networks by forcing the re-use of a cryptographic nonce with a key already in use by manipulating and replaying cryptographic handshake messages. Should the attack succeed, it's then possible to monitor any ...
