# Match-ADHashes

Builds a hashmap of AD NTLM hashes/usernames and iterates through a second list of hashes checking for the existence of each entry in the AD NTLM hashmap

<#

.NAME

    Match-ADHashes

.SYNOPSIS

    Matches AD NTLM Hashes against other list of hashes

.DESCRIPTION

    Builds a hashmap of AD NTLM hashes/usernames and iterates through a second list of hashes checking for the existence of each entry in the AD NTLM hashmap

        -Outputs results as object including username, hash, and frequency in database

        -Frequency is included in output to provide additional context on the password. A high frequency (> 5) may indicate password is commonly used and not necessarily linked to specific user's password re-use.

.PARAMETER ADNTHashes

    File Path to 'Hashcat' formatted .txt file (username:hash)

.PARAMETER HashDictionary

    File Path to 'Troy Hunt Pwned Passwords' formatted .txt file (HASH:frequencycount)

.PARAMETER Verbose

    Provide run-time of function in Verbose output

.EXAMPLE

    $results = Match-ADHashes -ADNTHashes C:\temp\adnthashes.txt -HashDictionary C:\temp\Hashlist.txt 

.OUTPUTS

    Array of HashTables with properties "User", "Frequency", "Hash"

    User                            Frequency Hash                            

    ----                            --------- ----                            

    {TestUser2, TestUser3} 			20129     H1H1H1H1H1H1H1H1H1H1H1H1H1H1H1H1

    {TestUser1}                     1         H2H2H2H2H2H2H2H2H2H2H2H2H2H2H2H2

.NOTES

    If you are seeing results for User truncated as {user1, user2, user3...} consider modifying the Preference variable $FormatEnumerationLimit (set to -1 for unlimited)
