Requirements

Python >= 3.6

Warning

Only default domain policy is checked for now. If custom GPO is used for password policy, it won't be detected. That's some work in progress.

Installation

From pip

python3 -m pip install sprayhound

From source

sudo apt-get install libsasl2-dev python3-dev libldap2-dev libssl-dev
git clone git@github.com:Hackndo/sprayhound.git
cd sprayhound
python3 setup.py install

Usage

Unauthenticated

When used unauthenticated, sprayhound won't be able to check password policies. Account could be locked out.

# Single user, single password
sprayhound -u simba -p Pentest123.. -d hackn.lab -dc 10.10.10.1

# User list, single password
sprayhound -U ./users.txt -p Pentest123.. -d hackn.lab -dc 10.10.10.1

# User as pass
sprayhound -U ./users.txt -d hackn.lab -dc 10.10.10.1

# User as pass with password lowercase
sprayhound -U ./users.txt --lower -d hackn.lab -dc 10.10.10.1

# User as pass with password uppercase
sprayhound -U ./users.txt --upper -d hackn.lab -dc 10.10.10.1

Authenticated

When providing a valid domain account, sprayhound will try and find default domain policy and check badpwdcount attribute of each user against lockout threshold. If too close, it will skip these accounts.

# Single user, single password
sprayhound -u simba -p Pentest123.. -d hackn.lab -dc 10.10.10.1 -lu pixis -lp P4ssw0rd

# All domain users, single password
sprayhound -p Pentest123.. -d hackn.lab -dc 10.10.10.1 -lu pixis -lp P4ssw0rd

# User as pass on all domain users
sprayhound -d hackn.lab -dc 10.10.10.1 -lu pixis -lp P4ssw0rd

# User as pass with password lowercase
sprayhound --lower -d hackn.lab -dc 10.10.10.1 -lu pixis -lp P4ssw0rd

# User as pass with password uppercase
sprayhound --upper -d hackn.lab -dc 10.10.10.1 -lu pixis -lp P4ssw0rd

Difference between badpwdcount and lockout threshold can be tuned using --threshold parameter. If set to 2, and password policy locks out accounts after 5 login failure, then sprayhound won't test users with badpwdcount 3 (and more).

sprayhound -d hackn.lab -dc 10.10.10.1 -lu pixis -lp P4ssw0rd --threshold 1

Bloodhound integration

When sprayhound finds accounts credentials, it can set these accounts as Owned in BloodHound. BloodHound information should be provided to this tool.

# -nh: Neo4J server
# -nP: Neo4J port
# -nu: Neo4J user
# -np: Neo4J password
sprayhound -d hackn.lab -dc 10.10.10.1 -lu pixis -lp P4ssw0rd -nh 127.0.0.1 -nP 7687 -nu neo4j -np bloodhound
