AzureAD_Autologon_Brute

Brute force attack tool for Azure AD Autologon

https://arstechnica.com/information-technology/2021/09/new-azure-active-directory-password-brute-forcing-flaw-has-no-fix/

Update - 2024.02.21

The AADSTS81016 that people were reporting now seems to indicate a valid account.

Thanks to @rootsecdev for validating that password spray functionality still works!

Usage:
python3 azuread_autologon_brute.py -d intranet.directory -U users.txt -p Password1
[~/AzureAD_Autologon_Brute] # python3 azuread_autologon_brute.py -d intranet.directory -U users.txt -p Password1
Domain is  intranet.directory
Setting password as: Password1
Reading users from file: users.txt
