Hi all I have an RB951g, I forgot the login details and the device does not want to hard reset. Is it possible to hack this device as I can see the ssid I previously set up on the device. I am connected to the device via wifi as I remembered the wifi. Please can someone help me? Thanks

Can you please upload the "probable-v2-top12000.txt" file

what do these do

how do you actually use this program on a since I'm new to this kind of program

i am new to python and programming great code any one say how to write code like this and some modules that needed for hacking 😎👏

how to you get it to work on something

Just how do you use this program on a website. I am new in this :)

Hello!

Can I use it on my phone? and how can I use it? Because when I paste the example to the code I get an IndentationError to bruteforce()
Sorry I'm a beginner.

if i want to do this on website how i tell to put password in website

how do i make so i can use this on website pls men i need know

LOL

Tolong buat lebih sederhana... Saya baru di di bidang ini

Hi, I just tested your program, it defines a bruteforce subprogram that can be used to bruteforce a known password and see how long it takes to do it (the example at the end shows how it works with passwords you enter yourself), but how can you use this program to actually crack an unknown password?
