# This script takes an input file containing Node names to be marked in Neo4j database as
|
|
# owned = True. The strategy for working with neo4j and Bloodhound becomes fruitful during
|
|
# complex Active Directory Security Review assessments or Red Teams. Imagine you've kerberoasted
|
|
# a number of accounts, access set of workstations or even cracked userPassword hashes. Using this
|
|
# script you can quickly instruct Neo4j to mark that principals as owned, which will enrich your
|
|
# future use of BloodHound.
