protect
dpapi::protect protects data via a DPAPI call. It has the following command line arguments:/c: displays the output as a C programming language char array/out: save the results to a file/data: the data to encrypt/system: the data are encrypted under the system account context. It will be visible in theflags : system/prompt: the Mimikatz's additional DPAPI prompt GUI/entropy: the entropy for the encryption/machine: The data are encrypted under the machine account context. It will be visible in theflags : local_machine/description: provide a description for the blob data
It must be noted that during our tests when using the
/system parameter, even running Mimikatz with token::elevate, the following error was raisedmimikatz # dpapi::protect /data:"Hello Mimikatz" /system
data : Hello Mimikatz description : flags : system ; prompt flags: entropy :
ERROR kuhl_m_dpapi_protect ; CryptProtectData (0x00000057)
