Collaborate Disseminate
If someone is coding a secure connection library, I’d have expected this to stick out like a red flag to them.
Why on earth would someone code logic like this (anyone working on it must have understood the basics enough to … Continue reading Why didn’t anyone think "use zero nonce and continue handshake" was a problem or at least strange in wpa-supplicant before now?
What are the real-world consequences of the WPA2 KRACK attacks on older Windows systems (XP/Vista) and iOS devices (10 and older) that will not be patched?
I am aware of another question on this site that asks about the cons… Continue reading Consequences of the WPA2 KRACK attack on older Windows and iOS clients
When a client is forced to reinstall the key and to reset the nonce and the replay counter, what does it imply for the future communication between the client and the AP? There’s an adversary in the MITM position who now can decrypt packet… Continue reading Can the client communicate with the AP after a KRACK attack?
From my reading of the whitepaper it is the 4-way handshake that is vulnerable, but WPA2-Enterprise uses a RADIUS server for authentication, so is it also exploitable? And if so, how?
Continue reading Is WPA2-Enterprise affected by the KRACK attack?
From what I’ve read, the issue is as simple as performing step 3 of a 4-step handshake and the consequences of performing that step more than once. Considering the complexity of these kinds of algorithms, I’m somewhat surpris… Continue reading Why wasn’t the KRACK exploit discovered sooner?
Does using a VPN protect against KRACK? How does this work? How can it be bypassed?
I use a commercial VPN on my laptop and on Android. Is an OpenVPN connection to your home a good way to protect your devices?
Trying to learn….
The ultimate difference between the vulnerability outlined in the answer posted here and KRACK attack is that with KRACK attack, the attacker does not need the AP pass phrase?
KRACK attacks work against networks using WPA and WPA2 encryption Continue reading Wi-Fi at risk from KRACK attacks – here’s what to do
Following on from this question, I am unclear on which of the following steps are sufficient to protect a WPA2-based wifi connection from the KRACK flaw:
Patching the AP (e.g. router)
Patching the client (e.g. mobile device… Continue reading To sufficiently protect against KRACK is patching the client, the AP, or both, required?
Nearly everyone using Wi-Fi to connect to the internet is being urged by experts to patch their devices on Monday as a new widespread vulnerability to virtually all modern protected Wi-Fi networks leaves a huge swath of internet traffic potentially open for eavesdropping. The vulnerability known as KRACK, short for Key Reinstallation Attack, allows data previously believed to be safely encrypted to be read and manipulated. Importantly, KRACK requires an attacker to be within Wi-Fi range in order to exploit the weakness in WPA2, the 13-year-old protocol securing virtually all modern Wi-Fi networks. “This can be abused to steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos, and so on,” researcher Mathy Vanhoef from the Belgian university KU Leuven explained. “The attack works against all modern protected Wi-Fi networks. Depending on the network configuration, it is also possible to inject and manipulate data. For example, an attacker might be able to […]
