![]() TL DR Deauthentication Attack Gist for the Knowledgableĭeauthentication attack is a type of denial of service attack that targets communication between a user ( or all users ) and a Wi-Fi access point. □ If you know what you are doing and only looking for a simple command list, I got you fam □ | How to prevent the attack and take the necessary precautions.| Why would you want to attack in that way.So, this is not going to be a simple how-to, this article will be divided into 4 parts: In my humble opinion, when a hacker learns about a new attack, he or she must also learn how to prevent it. I try to assist the user to conenct to the right wifi (or even turn wifi on) with the, hacker curious soon to be 1337 hacker legends and welcome to my first serious article/tutorial on the realm! My name is d3ad R1nger and today you will learn the theory and also a practical example of a wireless network attack called deauthentication.I try to verify if the user is currently connected to the right wifi.I fallback to Settings.ACTION_WIFI_ADD_NETWORKS where possible.If the user is not connected to the right wifi I would try to use the _WIFI action to let the user to connect to the right wifi.However the ConnectivityManager API don't return the actual SSID, that drives me crazy. To do so I already own the permissions ACCESS_WIFI_STATE, ACCESS_NETWORK_STATE, ACCESS_COARSE_LOCATION and ACCESS_FINE_LOCATION. I need to verify if the steps before worked and the user is actually connected to the desired wifi.On Android 11+ I can fallback to the Settings.ACTION_WIFI_ADD_NETWORKS intent which can always add Wifis (with the downside that the user can share the wifi password).On Android 10 I can just check if I'm connected with the right wifi, well at least theoretically (see step 7). When the user rejected my suggestion I'm almost out of the game I can never ask the user again (well technically there is a well hidden feature where you can switch the permission, but no user will ever find it).However I still don't know if the device actually connected with the wifi. On Android 11 this is possible (see step 2). I cannot verify on Android 10 if my suggestion was accepted. When the user accepts my suggestion I'm fine so far.Wds-mode=disabled wds-default-bridge=none wds-ignore-ssid=no bridge-mode=enabled default-authentication=no default-forwarding=yes default-ap-tx-limit=0 Wds-default-bridge=none wds-ignore-ssid=no bridge-mode=enabled default-authentication=yes default-forwarding=yes default-ap-tx-limit=0ĭefault-client-tx-limit=0 hide-ssid=yes security-profile=default compression=noġ R name="wlan2" mtu=1500 l2mtu=1600 mac-address=B8:xx:xx:xx:xx:03 arp=enabled interface-type=Atheros AR9888 mode=ap-bridge ssid="xxxxx-5" frequency=5660īand=5ghz-a/n/ac channel-width=20/40/80mhz-XXXX secondary-frequency="" scan-list=default wireless-protocol=802.11 vlan-mode=no-tag vlan-id=1 0 R name="wlan1" mtu=1500 l2mtu=1600 mac-address=B8:xx:xx:xx:xx:04 arp=enabled interface-type=Atheros AR9300 mode=ap-bridge ssid="xxxx-2" frequency=autoīand=2ghz-b/g/n channel-width=20/40mhz-XX secondary-frequency="" scan-list=default wireless-protocol=802.11 vlan-mode=no-tag vlan-id=1 wds-mode=disabled
