The only vulnerability so far is a dictionary attack, which fails if the passphrase is robust enough. Furthermore, WPA provides counter-measures against active attacks (traffic reinjection), includes a stronger message integrity code (michael), and has a very robust authentication protocol (the 4-way handshake). There has been some disinformation in the news about the “flaws” of TKIP:įor now, TKIP is reasonably secure but it is also living on borrowed time since it still relies on the same RC4 algorithm that WEP relied on.Īctually, TKIP (WPA1) is not vulnerable: for each packet, the 48-bit IV is mixed with the 128-bit pairwise temporal key to create a 104-bit RC4 key, so there's no statistical correlation at all. How can I know what is the key length ?ĭiscard the first 256 bytes of RC4's output. Aircrack-ng defaults to the PTW method and you must manually specify the Korek method in order to use it. Additionally, PTW only works properly with selected packet types.
Keep in mind that it can take 100K packets or more even using the PTW method. PTW is limited to 40 and 104 bit keys lengths.

Using this technique, 40-bit WEP (64 bit key) can be cracked with as few as 20,000 data packets and 104-bit WEP (128 bit key) with 40,000 data packets. With the introduction of the PTW technique in aircrack-ng 0.9 and above, the number of data packets required to crack WEP is dramatically lowered. The figures above are based on using the Korek method. Then if the key is not found, restart aircrack-ng (without the -n option) to crack 104-bit WEP. Thus, it is recommended to run aircrack-ng twice: when you have 250,000 IVs, start aircrack-ng with “-n 64” to crack 40-bit WEP. There is no way to know the WEP key length: this information is kept hidden and never announced, either in management or data packets as a consequence, airodump-ng can not report the WEP key length. Usually, 40-bit WEP (64 bit key) can be cracked with 300,000 IVs, and 104-bit WEP (128 bit key) can be cracked with 1,500,000 IVs if you're out of luck you may need two million IVs, or more. The number of required IVs depends on the WEP key length, and it also depends on your luck. To learn more about Wireshark is probably a good place to start.WEP cracking is not an exact science.Who knows, but that recipe led to plenty of frustration in the community as more of us migrate to Mac’s for Unix capability under the hood while still maintaining the corporate application support from business suite applications.

Gerald touched on the interoperability problems with Mac OS X and it sounded as if there was some issues with libpcap, Mac and Wireshark. Log out and log back in to restart your X session.

Thanks to XQuartz the Mac install is as easy as installing two applications.
For whatever reason the WireShark download site does not list XQuartz the key to end the pain that I saw anywhere. misconception. The WireShark installation process prior to XQuartz was long and convoluted and more often than not would end miserably. For troubleshooting or supporting SLAs it is often the only tool the defines fact vs. Packet capture utility are vital for developers, network and systems engineers alike. Seems like the WireShark install on Mac OS X has always been a total disaster for me.
