Wi-Fi Jammer ( deauthentication attack )

For some time now, I became interested in network security and came across an article on how to make a Wi-Fi Jammer (deauthentication attack). I did not even suspect that you can make someone's life so easy and simple. To make a Jammer All we need is esp8266. The principle of operation is very simple. Our device pretends to be a router and sends information (deauthentication packets) to network users to disconnect. This option does not always work, but it is enough to set an attack on a specific device and you're done. I haven't been able to find information on how to defend myself against such an attack, but maybe one of the forum members knows and will share their knowledge. Remember that you can only use this for educational purposes and testing your OWN network. Link to the video with step-by-step instruction youtube.com/watch?v=9UgFafZhONI
Instruction:
Uploading the program to ESP8266:
1) Download the file with the files forbiddenbit.com/239/
2) Unpack the Wi -Fi_Jammer.zip file
3) Install the driver for CH340 ch341SER / SETUP.EXE
4) Open ESP8266Flasher.exe.
Select deauther_2.1.0_1m.bin in the file.
In Operation, select the COM port from ESP8266 and click FLASH.







ATTACK:
1) Connect to wpnet, password: deauther
2) Open the address of the browser entry 192.168.4.1
3) Accept the terms
4) Select your network from the list
5) Go to the attack tab, select deauth and click start. Now the devices connected to the network will be disconnected.
If you select an attack beacon, multiple networks will be created

Interesting. If I understand correctly from the cursory information, the device copies the MAC of the indicated router and to the selected target (network client), impersonating the router, sends frames... [Read more]
I remember the Gargoyle CC probably was susceptible to this and the FritxBox not, but it actually shows how easy it is to disconnect someone. [Read more]
I am asking my colleague to respect the correct technical terminology. The device does not qualify as a jammer. It is enough for us that there is already a sufficiently large number of people who call... [Read more]
I was making a similar jammer with the Wemos d1 mini. Newer, more decent routers are more resistant to this type of action, and not all of them can be disrupted [Read more]
If you choose to attack the entire network it rarely works, but if you choose one device from the network it always worked in MY case, I checked on 3 laptops, 2 TVs and 5 phones and it fired every tim... [Read more]
and you can upset your neighbor with this? [Read more]
Such an attack can be detected, the detector is also on ESP8266. You can even buy a ready-made device from a Chinese. https://www.aliexpress.com/item/32942948304.html [Read more]
If someone has a free evening, he can make a simple program that will allow anonymous use of the Internet for free - just make a loop on ESP that activates WPS every minute, put a tile by the window and... [Read more]
Then finally if: ? You host two types of attack - bruteforce and regular occasion listening. In the first case, most devices block WPS after 2-3 failed pin bend attempts, so it will take some... [Read more]
WPS on ESP only works for a minute (or maybe two, I don't remember) and if it doesn't find any router, it turns itself off. This loop is for the WPS to be active all the time and waiting for an... [Read more]
Still do not understand. Or Still you are listening for WPS frames, or you are actively attacking WPS. What do you mean by "turn on WPS for a minute"? [Read more]
Normal WPS pairing seems to work by clicking WPS on your router, running WPS in the client and without giving anything (weak passwords etc) they will find, exchange the keys and "pair". Hence, if you run... [Read more]
"Normal" WPS pairing requires a PIN printed on the AP. Inventions that don't require a pin work like this: https://en.wikipedia.org/wiki/Wi-Fi_Protected_Setup#Modes So the 2 minutes between... [Read more]
I have not met the version with the pin, but maybe I just had such equipment in my hands. The given description of the version without the pin is consistent with what I wrote earlier. The percentage... [Read more]
WPS with PIN? What is the point of that? Digital TV via internet in Orange works in such a way that their devices cannot be paired differently .. There is simply no other option than via WPS .. [Read more]
When configuring, you only enter 8 numbers, while WPA-Passphrase can be set to several dozen alphanumeric characters. As for Orange - there is really no option to manually set a password? Imho absurd... [Read more]
I use wifi zone wps love it for the ease of hacking (internet access and routers) The neighbors are surprised when it shows passwords and turns off wps [Read more]
I also had a jammer. My router was quite resilient, but the jammer slowed the internet down terribly. [Read more]
OpenWRT / LEDE has been configuring the option to detect this attack for some time, the only thing is an attack targeting network clients, not a router and basically a standard used for a malicious pu... [Read more]
