A hive is a logical group of keys, subkeys, and values in the registry that has a set of supporting files loaded into memory when the operating system is started or a user logs in.
If we can access to registries and get registry hives, the password hashes can be dumped. Copy three hives (SAM, SECURITY, SYSTEM) to arbitrary direcotyr where we can access.
After that, we can dump password hashes from hives.
After dumping hashes, we can crack them. First, we extract NTLM from the hash. For example, the dumped hash is below.
