Try looking for it here from steph. First, you need to get the credentials saved in Windows Credential Manager. It uses DPAPI encryption (CryptProtectData) to bind the user or computer’s MasterKey.

Abusing DPAPI Secrets to Move Laterally (impacket-dpapi)
Once we get access to the Domain Controller, the next goal will be to scale privileges and finally become Domain Admins.
Looking for possible climbing vectors, we identified the option of abusing DPAPI (Data Protection API), which can allow us to access protected credentials and move laterally through the domain.
On the following routes it is where the credentials protected by DPAPI are usually stored.
In the case of the user steph.cooper has a credential called C8D69EBE9A43E9DEBF6B5FBD48B521B9located in C:\Users\steph.cooper\AppData\Roaming\Microsoft\Credentials.
This credential is hidden, so you can unload it through the module downloadwhich offers evil-winrm, we must remove the attribute Hiddenand System. Then, you will let us download the file to our local computer.

DPAPIDPAPI-protected credentials are encrypted using a specific Master Key user, derived from your password.
These Master Keys are usually stored on the following route:
In our case, we found two possible Master Keys in that location. We know that one of them is the one used to protect the credential we downloaded before.
Tools like Mimikatz or winPEAS allow them to directly identify which Master Key corresponds to each secret, but in this case we did it manually by testing both, and we determined that the correct one was: 556a2412-1275-4ccf-b721-e6a0b4f90407.
Since he has the attributes Hiddenand SystemWe’ll take them away through attrib -h -sand we can download the master key through the module downloadof evil-winrm.
