Function Invoke-AzurePasswordSpray {
<#
.SYNOPSIS
This cmdlet is used to perform a password spray attack against Azure accounts using legacy "Basic" Authentication
.DESCRIPTION
The cmldet performs a password spray attack against Azure using by default, basic authentication against the legacy Office365 reporting API. This script will currently not work if legacy authentication in Azure AD is blocked. The -Username or -UserFile parameters should contain a list of email addresses to test passwords against. Specify passwords to try with the -Passwd or -PassFile parameter. Use the -SleepSeconds and -RoundRobin parameters to prevent possible lock outs from too many failed attempts.
.PARAMETER UserName
Define a list of usernames or a single user to peform your password check against
.PARAMETER UserFile
Set the path location of a file containing a list of user names you wish to test against
.PARAMETER Passwd
Define a single password or ann array of passwords to try against your userlist
.PARAMETER PasswdFile
Set the path location of a file containing a list of passwords to try
.PARAMETER Authentication
Define the type of authentication used when attempting the password spray. This currently only supports Basic authentication. I plan to add modern authentication later on
.PARAMETER SleepSeconds
Define the number of seconds to wait before attempting the next password
.PARAMETER RoundRobin
This switch parameter indicates you wish to try a single password against each username before moving to the next value. The default execution tests each password against a username
.EXAMPLE
Invoke-AzurePasswordSpray -UserName "rob@domain.com","john@domain.com" -Passwd 'Password123!','asdf123!'
# This Example tests the passwords defined against the list of usernames defined
.EXAMPLE
Invoke-AzurePasswordSpray -UserName "rob@domain.com","john@domain.com" -Passwd 'Password123!','asdf123!' -SleepSeconds 60
# This Example tests the passwords defined against the list of usernames defined with a 60 second wait before the next sign in attempt
.EXAMPLE
Invoke-AzurePasswordSpray -UserName "rob@domain.com","john@domain.com" -Passwd 'Password123!','asdf123!' -SleepSeconds 60 -RoundRobin
# This Example tests the passwords defined against the list of usernames defined with a 60 second wait before the next sign in attempt. This performs authentication attempts in a Round Robin fashion for the defined usernames
.EXAMPLE
$UserNames = "rob@domain.com","john@domain.com","dixie@domain.com","chris@domain.com"
$UserNames | Invoke-AzurePasswordSpray -Passwd "Password123!" -RoundRobin
# This Example tests the passwords defined against the list of usernames defined in a Round Robin fashion
