    Major Flaw in Wi-Fi Protected Access Discovered


    Posted: 28 Dec 2011
    The now widely used Wi-Fi Protected Access (WPA) standard is apparently not as protected as router makers had hoped. According to a new study, the PIN codes used to lock down the system can be brute forced on many devices by inputting incorrect PIN codes. Millions of routers and access points could be affected.

    I was just reading about that

    I actually just clicked the link, and you have the wrong terminology. You are confusing Wi-Fi Protected Access with Wi-Fi Protected Setup, the two are totally different.

    I remember a Japanese guy saying well over a year ago that he would be able to crack WAP protection within two minutes using cracking software he'd developed on the very same principles, I'm sure it was published on El-Reg's website at the time...

    I think that error has been fixed.

    Since my wireless networking classes, I've always thought that the WPS (Easy Setup) was a disaster waiting to happen.

    WPA-TKIP (Encryption) has been cracked.

    Sorry?
    I think that the links make it clear that WPS and WPA-TKIP are now vulnerable.

    WPS (Easy Setup) can be broken by a "brute force" attack.

    WPA-TKIP (Encryption) has been broken by at least two different groups of researchers (and a "blogger").
    Another dozen used WPA (Wi-Fi Protected Access), with the built-in Temporal Key Integrity Protocol (TKIP) security protocol. There, I used a rainbow table, a list of the most common WPA passwords, to pop open APs almost as quickly as I could open up a coke bottle. I also managed to pry open a pair of routers using WPA2 (Wi-Fi Protected Access 2) with TKIP using rainbow table.

    So is AES still decent, or has it been broken too/

    CCMP (AES) is still good

    Currently AES is "still standing".
    Who knows for how long though.

    If you really want to secure a Wi-Fi network in 2010 you must use WPA2 with Counter Mode with Cipher Block Chaining Message Authentication Code Protocol (CCMP), aka Advanced Encryption Standard (AES).

    The authors say that the attack can be defeated by deactivating QoS, or by switching from TKIP to AES-based CCMP.

    I'm a little confoosed... what I'm seeing in the news concerns the weakness of the WPS PIN for assigning a security key across wireless devices from a router which is WPS equipped.

    Many months ago there were claims of WEP security being crackable.

    Most of us know to use stronger methods of encryption.

    The present issue appears to relate uniquely to WPS and the PIN number generated as being vulnerable.

    Wi-Fi Protected Setup easily unlocked by security flaw ? The Register
