Due to the overwhelming attendance and response we got to the recent WPA2 Hole196 webinar, we did not have time to answer all the questions asked during the webinar. In this post, we are keeping our promise and answering those webinar questions.
By the way, the webinar slides and recording from this webinar as well as answers to the frequently asked questions on Hole196 and a white paper are available here.
So here we go!
Ban of WEP & TKIP
Wi-Fi Alliance has (finally) decided to take some giant steps in improving the state of wireless security. Starting Jan 2011, TKIP will be disallowed on new APs and from 2012, it will be disallowed on all Wi-Fi devices. Come Jan 2013, WEP will not be allowed on new APs and from 2014, WEP will be disallowed on all Wi-Fi devices. This is the good news. But, let us also get to the “bad” news.
Last week we saw Google facing legal tangles for “accidental interception” of WiFi signals and this week it was Apple facing “mysterious disappearance” of WiFi signals during iPhone-4 demo at WWDC keynote. So “what’s going on”, does WiFi not like us any more? Well, because these things struck Eric and Steve, we got to hear about them, but in fact they strike Tom, Dick and Harry everyday.
But there is a way out of this WiFi chaos. Read more…
What % of WiFi laptop users in your organization are vulnerable to WiFishing attacks? The odds are very high that you don’t have an exact answer.
WiFish Finder is a tool for assessing whether WiFi devices active in the air are vulnerable to ‘Wi-Fishing’ attacks. Assessment is performed through a combination of passive traffic sniffing and active probing techniques. Most WiFi clients keep a memory of networks (SSIDs) they have connected to in the past. Wi-Fish Finder first builds a list of probed networks and then using a set of clever techniques also determines security setting of each probed network. A client is a fishing target if it is actively seeking to connect to an OPEN or a WEP network. Clients only willing to connect to WPA or WPA2 networks are not completely safe either!
To find out why – you’r welcome to try out WiFish Finder a vulnerability assessment tool built by Sohail and Prabhash, members of security research team at AirTight Networks. Sohail is presenting WiFish Finder at DefCon 2009 today. Demo version of this tool (Version 1.0) can be downloaded from http://airtightnetworks.com/fileadmin/downloads/WiFishFinder-v0.1.zip
Sohail is also planning to release WiFish Finder Ver 2.0 with speed, usability and feature enhancements (such as PEAP vulnerability detection) upon his return from Las Vegas. To download full featured version of WiFish Finder and for tips on protecting your laptop from Wi-Fishing attacks, visit http://www.airtightnetworks.com/wifishfinder.This URL will be operational in 4-5 days.
What % of WiFi laptop users in your organization are vulnerable to WiFishing attacks? Well, you only have to wait another 4-5 days to find out the answer!
