The promise of 802.11ax – What should we expect?

What is new in 802.11ax
802.11ax promises a lateral progression of the WiFi standard. Until now, all new WiFi specifications were focused on improving the peak data rates. 802.11ax takes a side step and promises higher efficiency rather than higher peak rates. It promises to improve the total throughput in a cell and deliver more data to the clients rather than try to improve the speed at which the data is transmitted. 802.11ax features will be available in 2.4 GHz band as well (as opposed to 802.11ac which was available only in 5GHz).

About One CVE at the Tail End of KRACK: 13088
Posted by Hemant Chaskar on Oct 27, 2017

In my last video blog on KRACK attack, I explained the technical details of workings and countermeasures for 9 out of 10 CVEs. The one I did not discuss in detail was CVE-2017-13088. At the time there wasn't enough information available on it and though it looked like the twin of CVE-2017-13087, due to differences between how group keys are distributed in MFP mode versus non-MFP mode, it required separate consideration.  After receiving more details from the researcher (@vanhoefm), I am prepared to share  information about CVE-2017-13088 and the appropriate countermeasures.

WPA2 Key Reinstallation Vulnerabilities (KRACK) Explained
Posted by Hemant Chaskar on Oct 16, 2017

Researchers from the University of Leuven (@vanhoefm and team) have discovered flaws in WPA2 implementation in clients and APs. These flaws create vulnerabilities for replay and decryption attacks on packets transferred over WiFi links. They have named them KRACKs (Key Reinstallation AttaCKs). Both 802.1x (EAP) and PSK (password) based networks are affected. These vulnerabilities have been cataloged under 10 CVEs. In the series of videos below, I explain these CVEs in detail with Vivek Ramachandran, Founder and CEO of Pentester Academy.
