When a client joins a network, it executes the 4-way handshake to negotiate a fresh encryption key. It will install this key after receiving message 3 of the 4-way handshake. Once the key is installed, it will be used to encrypt normal data frames using an encryption protocol. However, because messages may be lost or dropped, the Access Point (AP) will retransmit message 3 if it did not receive an appropriate response as acknowledgment. As a result, the client may receive message 3 multiple times. Each time it receives this message, it will reinstall the same encryption key, and thereby reset the incremental transmit packet number (nonce) and receive replay counter used by the encryption protocol. We show that an attacker can force these nonce resets by collecting and replaying retransmissions of message 3 of the 4-way handshake. By forcing nonce reuse in this manner, the encryption protocol can be attacked, e.g., packets can be replayed, decrypted, and/or forged. The same technique can also be used to attack the group key, PeerKey, TDLS, and fast BSS transition handshake.
While I do agree with your sentiment, I have to admit that I take issue with your use of the expression
..the definition of insanity doing the same thing over and over and expecting a different result?
. Every time I hear that I cringe.
https://www.psychologytoday.co... To be clear, insanity is a legal term pertaining to a defendant's ability to determine right from wrong when a crime is committed. Here's the first sentence of law.com's lengthy definition:
Insanity. n. mental illness of such a severe nature that a person cannot distinguish fantasy from reality, cannot conduct her/his affairs due to psychosis, or is subject to uncontrollable impulsive behavior.

Well done sir!
Indeed it does :)
I think a "Tommy" reference would have been more suitable here.
...who probably believes that Trump has the power to press the nuclear button out of personal pique.
He does. Frightening thought now aint it?
Wish I had mod points today :)
According to Vanhoef, when using WPA-TKIP or GCMP for encryption the bad actor can decrypt, forge and inject packets.
Right and with tools like kismet/or whatever they're using now, it's rather easy to determine which AP you will attack based upon protocol.
No it is an attack on both. Though it appears that patched clients would be safe while connected to an upatched AP.
Can anyone shed any light on how serious this actually is? How easy is it to exploit this?
I don't want some theoretical answer, either. I want to know in very practical terms.
Is this as bad as the "Shellshock" bash bug and the "Heartbleed" OpenSSL bug were, where systems were being compromised within hours of these bugs becoming widely known?

BRAVO! +1 if I had mod points left.
While I agree with the +4 moderation, I feel insightful to be more accurate than "Funny"
Ah yes and the eggdrops in our channel would immediately kick-ban any @aol.com users - All Only Lamers. Fun times.

It uses less. Type 'h' in the terminal and you will see the help screen entitled " SUMMARY OF LESS COMMANDS"
Mod parent up. This is not a "normal" APK rant.
Repealed? Or perhaps correctly interpreted.
As an American I approve OP's comment.
