Wi-Fi Protected Access(WPA,more commonly WPA2)handshake traffic can be manipulated to induce nonce and session key reuse,resulting in key reinstallation by a wireless access point(AP)or client.

An attacker within range of an affected AP and client may leverage these vulnerabilities to conduct attacks that are dependent on the data confidentiality protocols being used.

Attacks may include arbitrary packet decryption and injection,TCP connection hijacking,HTTP content injection,or the replay of unicast and group-addressed frames.

These vulnerabilities are referred to as Key Reinstallation Attacks orKRACKattacks.
KRACK attack allows other nasties, including connection hijacking and malicious injection.
Exploits affecting Windows 7-based CT, SPECT, PET scanners are publicly available.
