All WPA2 Wireless Networking is Vulnerable.

CERT Coordination Center (CERT/CC) has released information on Wi-Fi Protected Access II (WPA2) protocol vulnerabilities. Exploitation of these vulnerabilities could allow an attacker to take control of an affected system. The vulnerabilities are in the WPA2 protocol, not within individual WPA2 implementations, which means that all WPA2 wireless networking may be affected. Source: Vulnerability Note VU#228519

It is a vulnerability attacking all modern Wireless Access Point that use WPA2 protocol to exploit clients connected on the wireless network. Exploiting this vulnerability requires the following:

• Programming skills to run against the key reinstallation attacks (Kracks), currently the proof of concept script is not (yet) available to the public.
• The attacker needs to be close to the WAP, know the SSID which is broadcasting by default.
• Clone the wireless network and create a rouge channel.
• Forwarding traffic to the rouge wireless network.
• Initiate the SSLStrip tool to bypass SSL, commonly known as https that you see on a secured website.
• Use Wireshark tool or other network snipping tool to capture wireless network traffic. This will see all the data in plain text e.g. username and password.
• And do whatever they want on a stolen user credentials.

As you can see, the actions must be completed by someone who know how to initiate the attack. It is not designed for script kiddies.

To prevent this vulnerability, we must update all wireless devices. There is no available security patch posted on their website. I will check our vendor wireless device from time to time.

Watch the Demonstration.

Related: In 2002-2003, the WirelessCon Team (I am one of the member) actually won the first wardriving contest event in BlackHat Defcon. Then, 2nd place the following year. The contest is to find as many as unsecure Wireless Access Point (WAP) for a period of time using a DIY WI-FI antenna and Kismet Wireless or Netstumbler tool.

Alternative Solutions to secure your Wireless Network:

1. Check with your Wireless device vendor's website for security update.
2. Check with your cable service provider on how to fix/secure your wireless network.
3. A bit technical is to reconfigure your wireless access point (WAP) to only accept registered device to the network. This is a manual process to add the client wireless device (MAC address) to the WAP.

For PUBLIC Wireless Network. For example, shopping mall they offer free wireless access, coffee shop, dentist, etc. I recommend that you limit your connection to these public WIFI, unless you trust their network.
