I’m a little bit confused regarding the keystream. When installing the same session key again the nonce will be reset and start again.
Session Key + Nonce = Keystream?
The Keystream is now the part which is used to encrypt … Continue reading KRACK and Keystream
From the official FAQ on the vulnerability (emphasis mine):
So again, update all your devices once security updates are available. Finally, although an unpatched client can still connect to a patched AP, and vice versa, b… Continue reading Does only having one end of a wifi connection patched reduce the risks from KRACK?
KRACK may be the biggest vulnerability of the year – a flaw in the WPA2 protocol used to encrypt Wi-Fi communications.

| A serious flaw in the wireless protocol that secures all modern protected Wi-Fi networks has been discovered. If your device supports Wi-Fi, it is most likely affected. This feasible attack, dubbed KRACK, could abuse design or implementation flaws in the Wi-Fi standard, not some specific hardware.

I understand running a website with HSTS can help prevent an attacker using KRACK to downgrade the website to serve HTTP requests.
What if our web server does not support HSTS?
IIS has a setting for a website where it c… Continue reading Can enforcing a website to serve SSL requests only prevent SSLstrip from working?
It is my understanding that EAP-TLS and EAP-TTLS do not trust in WPA2 4-Way handshake, essentially establishing an authenticated tunnel between client and server independant on the WPA2 protocol.
In this scenario, would KRAC… Continue reading Does EAP-(T)TLS mitigate against KRACK?
I’m always using Wifi networks, since I move a lot. But I don’t think I can afford for the moment a VPN (I know they’re cheap) to protect myself against KRACK when connecting to those Wifi networks.
So is there a way that ca… Continue reading How can I protect myself from KRACK when I can’t afford a VPN?
After Heartbleed was announced, a number of tests popped up that let me test if a server I was connecting to was patched, unpatched or unknown. For example, https://filippo.io/Heartbleed/
Is such a test possible for KRACK? I… Continue reading Is there a test for KRACK (devices and routers)?
Apologies if this is already answered in the whitepaper, I’m not going to get chance to read it for a few days due to a hectic schedule, but I am already fielding questions from non-techies reading non-technical media news st… Continue reading Does KRACK break TLS?
I updated my Ubuntu 14.04 LTS.
My /var/log/apt/history.log says that linux-signed-image-3.13.0-134-generic:amd64 has been installed.
The changelog page says
linux (3.13.0-134.183) trusty; urgency=low
linux: 3.13…. Continue reading Has Ubuntu been patched for KRACKs?
