R7000, the KRACK WPA-2 vulnerability, and updates to Kong mod

This is in regards to the newest WPA2 vunlerability, "KRACK" (https://www.krackattacks.com/). I've read that base DD-WRT has been patched against the newest vulnerability - http://svn.dd-wrt.com/changeset/33525 - and I'm now wondering what the news is for us users of Kong Mod for our routers. Is there a new build on the horizon for the Netgear R7000s that includes any patches for the vulnerability?

Kong is reviewing this as we speak. It has already been patched in DD-WRT in general:


Kong has already posted some updated builds to his site today -- we'll be updating the community with the latest builds once confirmed.

Looking for a new build due

Looking for a new build due to KRACK for my R7000 (AC1700)


v3.0-r32170M kongac (06/11/17)

Yesterday I backed up my config, downloaded the stock firmware (completely lost where I stashed all my old files):


Downloaded Kongs .chk for updating a stock firmware:

dd-wrt.K3_R7000.chk (23851066 bytes)

Have one other file, not sure where I got it from or why:


It contains the same dd-wrt.K3_R7000.chk file dated *** June 12 2017 *** 23334970 bytes

Any idea where this came from or why I grabbed it (yeah, I forgot)?

Looking forward to updating of the router first, will work on clients (all laptops are Mint Sonya, maybe SOL on the Samsung phones running android 6 from what I read).

For sure that is our client

For sure that is our client wpa2 patch.

But Reading this  https://papers.mathyvanhoef.com/ccs2017.pdf   and this   https://www.krackattacks.com/  

I understand it could be happening already all the time to someone with
a very bad connection. As it is the protocol itself that allows it to

“Ha. I wonder what happens if that function is called twice”. At
the time I (correctly) guessed that calling it twice might reset the
nonces associated to the key. And since message 3 can be retransmitted
by the Access Point, in practice it might indeed be called twice.

the acces point should not allow that to happen if a secure connection
has already been established in the past.  Or it should ask for a total
new connection with no retransmit possibility. As that is the root of
the problem. the 2nd zero transmit and the purge of the real key. Our
patch will be something like. Never purge the key if the 4way handshake
has not been completed as it should in 1 flawless ride with no hickups

Since I have the Kong build

Since I have the Kong build as well I was hoping that I might be able to patch this today.  Is it recommended to wait for the Kong patch or would I be able to use the 10-17-2017-r33525 beta netgear-R7000-webflash.bin to update it or just level the router using the factory-to-dd-wrt.chk that has been provided by DD-WRT to patch my R7000?

Can anyone confirm if the

Can anyone confirm if the November 4th Kong release includes the patch for Krack?  I was not able to find release notes or mention of what is included in the release. (http://www.desipro.de/ddwrt/K3-AC-Arm/)
