Hi,   So this has been blowing up on Twitter, and does seem to be a pretty serious flaw with WPA2 rendering it pretty unusable for a security perspective. A few sites referencing this issue: https://www.krackattacks.com/ (Researchers' GitHub Pages site) https://arstechnica.com/information-technology/2017/10/severe-flaw-in-wpa2-protocol-leaves-wi-fi-traffic-open-to-eavesdropping/ https://www.theregister.co.uk/2017/10/16/wpa2_inscure_krackattack/ https://www.theguardian.com/technology/2017/oct/16/wpa2-wifi-security-vulnerable-hacking-us-government-warns Additionally, it looks like Ubiquiti have a firmware patch in the works to mitigate the issue.   For reference, here are the CVE numbers from the krackattacks.com page from above: CVE-2017-13077: Reinstallation of the pairwise encryption key (PTK-TK) in the 4-way handshake. CVE-2017-13078: Reinstallation of the group key (GTK) in the 4-way handshake. CVE-2017-13079: Reinstallation of the integrity group key (IGTK) in the 4-way handshake. CVE-2017-13080: Reinstallation of the group key (GTK) in the group key handshake. CVE-2017-13081: Reinstallation of the integrity group key (IGTK) in the group key handshake. CVE-2017-13082: Accepting a retransmitted Fast BSS Transition (FT) Reassociation Request and reinstalling the pairwise encryption key (PTK-TK) while processing it. CVE-2017-13084: Reinstallation of the STK key in the PeerKey handshake. CVE-2017-13086: reinstallation of the Tunneled Direct-Link Setup (TDLS) PeerKey (TPK) key in the TDLS handshake. CVE-2017-13087: reinstallation of the group key (GTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame. CVE-2017-13088: reinstallation of the integrity group key (IGTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame. What's the response from you guys regarding the possibility of getting this patched on our networks? (that is if a patch is possible, alternatively, what alternative authentication system do you recommend)   Cheers, Rob     ... View more
