Azure ATP posibilities to detect NTDS.dit dump

Hello,

 

Does Azure ATP detect activities related with getting a copy of the file NTDS.dit?

For example when dumping the file with native built in tools when Administrator is logged on to DC:

  • Leverage the NTDSUtil diagnostic tool available as part of Active Directory
  • VSSAdmin - Use Volume Shadow Copies via the VSSAdmin command

Thanks

      David Caddick, just want to clarify...have you ever tested this?

      I've deployed fresh new AATP 2 month ago, and once we dumped NTDS.dit on DC, ATP did not show any alert 😞 

      Double checked - ATP sensors were working fine on all DCs during the test.

        Might check using SMB maybe?
