A DoS attack that disconnects all devices from a target wifi network.

• The network's password is not required
• Tested on Kali NetHunter (Snapshot at the bottom)

IMPORTANT
In some occasions, network APs might operate on both 5GHz and 2.4GHz under the same BSSID name.
In order to truly bring the AP down, I usually run simultaneously two de-authers using 2 network interfaces: one for 2.4GHz and one for 5GHz.

The program iterates over all possible channels, and by sniffing 802.11 packets it determines which access points are available.
After the attacker chooses a target access point to attack, the program:

1. Continously sends spoofed deauthentication packets using broadcast mac address as the destination
2. Starts sniffing for clients that are connected to the AP by filtering for certain 802.11 packet frames and sending spoofed deauthentication packets to those clients in addition to the broadcast address

python3 wifi-deauth.py -i <iface>

• <iface> is the name of the network interface (i.e wlan0 or eth0) that supports packet injection
• The initial iteration over all channels might take a minute or two (depends on how many bands the interface supports)

• --bssid <name> - filter for a specific BSSID (this should shorten the channel-scanning duration), beware that the name is case-sensitive and whitespaces should be passed with an escape character (i.e -> new\ york)
• --channels <ch1,ch2> - scan for specific channels only, otherwise all supported channels will be scanned
• --kill (or run sudo systemctl stop NetworkManager) - kill NetworkManager service which might interfere with the attack
• --skip-monitormode - enable monitor mode manually (otherwise the program does it automatically)

• Check ifconfig to find the interface nickname
• Works for 2.4GHhz and 5Ghz
• Beware that some access points have protections against this kind of attack and therefore it might not work on them

• Linux OS
• A network adapter that supports monitor mode and packet injection
• Scapy library (listed in requirements.txt)

There's another project that performs a DoS attack on networks, which requires credentials but quite effective nonetheless.
