Next, they turn their WiFi receiver in to a WiFi Transmitter. Other password attacks are phishing in style as they also start with a DeAuth attack but then use a man-in-the-middle to collect passwords supplied by an unwitting user.įirst, the bad guy needs look around for a target which results in a wireless network target SSID. Some WiFi password attacks on WPA & WPA2 use brute force techniques along with DeAuth attacks to force a device offline then sniff out the WAP 4-way handshake when it reconnects. Service will be denied to WiFi devices connected and listening to messages from a specific SSID where a “ man in the middle” spoofs the SSID and transmits a message to all devices to disconnect from the WiFi network.ĭeAuth or deauthentication attacks are often part of a larger attack like those used to force clients to connect to an “Evil twin access point” where network packets can be captured. You can check out the Wikipedia description of a DeAuth Attack.Ī “DeAuth” attack is considered a denial of service attack. This article will be focusing on how to do a very basic WiFi “DeAuth” or deauthentication Attack using Kali Linux and the WiFi hacking tools included in it. I’ve been working in IT now for over 20 years and spend a percentage of my professional development time on InfoSec and IT Security related items as I feel its important to know how to use technology but also how criminals use the same technology to do bad things. My Journey into Wi-Fi Hacking and Deauthentcation Attacks

If the attacker is relentless, your only option is to change your SSID but they can just pick it up again and repeat the process. Even if device does connect briefly, we eventually intercept one of the packets and device will disconnect. This attack results in interruption in service for wireless devices by forcing them to disconnect from the target network.Īs the device tries to reconnect, we continue to send deauth packets. This article on deauthentication (Deauth) attacks on Hackernoon is a good a starting point.Ī Wi-Fi deauthentication attack is a Denial of Service (DOS) attack done over Wi-Fi by flooding the air with deauthorization frames while spoofing the Wi-Fi SSID of your target wireless network.
