Wi-Fi deauthentication is a type of denial-of-service attack that targets communication between a user and a wireless point access Wi-Fi access.
The final attack against wireless networks that we will evaluate is the denial-of-service attack, where an attacker deprives the legitimate user of access to a wireless network or makes the network unavailable, causing the error. Wireless networks are extremely sensitive to DoS attacks and it is difficult to locate the attacker.
To see the last access point, we will create a DoS attack on a network with deauthentication packages. Because 802.11 wireless protocol was created to support non-authorization during λήψη of a defined package, can be a catastrophic attack and there is no way to stop it.
The easiest way to “click” a legitimate user from a network is to target them with a stream of deauthentication packets. This can be done with the help of the tool suite aircrack-ng using the command below:
Mandate: aireplay-ng -0 0 -a (bssid) -c (Station) wlan0mon
This command specifies the type of attack as -0 , indicating that it is intended for an attack on identity. The second 0 (zero) starts a continuous stream of packet deauthentication, making the network unavailable to its users.
The Websploit framework is one tool ανοιχτού κώδικα που χρησιμοποιείται για σάρωση και ανάλυση απομακρυσμένων συστημάτων. Περιέχει διάφορα tools, including tools specifically for wireless attacks.
To get started, open a terminal and just type websploit. The Websploit interface is similar to that of recon-ng and the Metasploit Framework, and presents the user with a modular display.
Once started, use the show modules command to see the attack modules in the existing version.
Select the WiFi jammer using the command wifi / wifi_jammer.
As shown in the screenshot above, the intruder simply needs to use the set commands to define the various options. Then select run to start the attack.
If you want to set the bssid of the network on which you want to launch a deauthentication attack, just type “”And the same for the channel“".
