Paul1977: So, the consensus is that patching the AP only plugs a small part of the hole, and no matter what you do with your AP (short of turning it off) the client devices are vulnerable even when connected to a patched AP?

 

My understanding is a patched AP will not reissue a key but an unpatched client is capable of receiving one, which is what the attacker does - sends a zero (0) key to the client. Whether or not the patched AP would recognise this has occurred and refuse further comms I'm not sure.

EDIT: Which brings me to my next question. If patching the APs does plug all the holes, what is everyone doing with their wireless networks in the interim until clients patches are available (particularly corporate ones)? What about all the older Android devices that may not get patched, or may be weeks?

 

 

Remember many corporate wifi solutions will be using different security options than WPA2..

Still not sure on best practice here.

 

If I use a VPN to my home network when connecting via wifi while away from home does using a VPN mitigate any Krack issues?
At home seems to be a different matter - I've vulnerable if I use wifi as I cannot use a VPN to connect to my home network as I am already on my home network?

 

Can't see my LG G2 getting an update for this either. Might be time to upgrade soon.

A VPN on your device will not prevent KRAck, but it will mean that the traffic that is intercepted cannot be read for anything useful.

Correct, if you don't have a VPN on your device then any unencrypted traffic could possibly be seen.

I can still establish a tunnel to my OpenVPN server at home even when I am at home on the internal wifi.

If you have a data plan that will last then I guess you could just turn wifi off on your phone and just use mobile data (mmm those unlimited at 25gig plans are looking good now).

No.

 

If you use WPA2-TKIP (or GCMP, though that's fairly new) an attacker can send whatever packets they want into your network, including other devices on the network.

Mikrotik:  Fixed weeks ago (AP has no re-use vulnerabilities, client mode fixed)

 

Ubiquiti: Oh, it's in beta (client mode fix only)

I've always regarded WiFi as insecure so I guess none of this surprises me.

 

 

Best practice!

Vodafone position so far:

 

"Vodafone NZ is aware of the potential security threat to the WPA2 protocol which is used to encrypt and authenticate traffic on Wi-Fi networks.

Vodafone is working with manufacturers to update their devices to protect against vulnerability.

Vodafone NZ is not aware of any customers being directly affected by the threat, but urges people to keep their devices and security software updated"

 

Of course, I can't find any useful information about my Technicolor router. The admin interface only shows the current system software. I was unable to check if the current firmware is the latest one. The manufacture official website is useless too. 

 

So, I think is time to run to the hills and live in a remote cabin in the woods. Meanwhile, I'm using an ethernet cable for my laptop and mobile data for everything else.

Wonder if anyone will make AP's able to detect vulnerable client devices by sending duplicates of the part of the handshake that makes this happen and kick them off the wifi?
