On October 16, 2017, a research paper with the title “Key Reinstallation Attacks: Forcing Nonce Reuse in WPA2rdquo; was made publicly available.

This paper discusses seven vulnerabilities affecting session key negotiation in both the Wi-Fi P...
TLS implementations may disclose side channel information via discrepancies between valid and invalid PKCS#1 padding,and may therefore be vulnerable to Bleichenbacher-style attacks.

This attack is known as aROBOT attackquot;.
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.
