A (partial) Python rewriting of PowerSploit’s PowerView.

Fork me on GitHub.

HISTORY

As a pentester, I love using PowerView during my assignments. It makes it so easy to find vulnerable machines, or list what domain users were added to the local Administrators group of a machine, and much more.

However, running PowerView on a computer which is not connected to the domain is a pain: I always find myself using mimikatz’s sekurlsa::pth to run a Powershell prompt with stolen domain credentials, and that’s not easy to script. Plus, I’m a Linux guy and I’ve always found it a shame that there were no complete Windows/Active Directory enumeration tool on Linux.

That’s why I decided to rewrite some of PowerView’s functionalities in Python, using the wonderful impacket library.

Update: I haven’t tested the last version of PowerView yet, which can run from a machine not connected to a domain. I don’t know if it works correctly under Linux using Powershell. If anyone has had any experience with this at all, you can contact me, I’m really interested. We’ll see if pywerview has become obsoleted ;) but I think I’ll continue working on it eitherway: I’d still rather use Python than Powershell on Linux, and I’m learning a lot! Plus, it may integrated in existing Linux tools written in Python. It’s still great news that PowerView now supports machines not connected to the domain!

DISCLAIMER

This tool is far from complete (as you’ll see in the TODO section)! I still have a lot more awesome PowerView functionalities to implement (the user hunting functions, the GPO functions, the local process enumeration, etc.), but I still think it can be useful as is.

It’s also (very) possible that there are (many) bugs in the code: I’ve only tested the simplest test cases. If you use this tool during an assignment and you get an error, please, open an issue with the error and the conditions that triggered this error.

Also, blah blah blah, don’t use it for evil purposes.

Take a look at the wiki to see a more detailed usage of every command.

Attention: in every command, the used domain name must be the post-Win2k UPN, and not the Win2k compatible name.

For example, my domain name is uselessdomain.local. The Win2K compatible name is USELESSDOMAIN. In every command, I must use ``uselessdomain.local`` as an argument, and not USELESSDOMAIN.

TODO

• Many, many more PowerView functionalities to implement. I’ll now focus on forest functions, then inter-forest trust functions

• Lots of rewrite due to the last version of PowerView

• Implement a debugging mode (for easier troubleshooting)

• Gracefully fail against Unix machines running Samba

• Support Kerberos authentication

• Perform range cycling in get-netgroupmember

• Manage request to the Global Catalog

• Try to fall back to tcp/139 for RPC communications if tcp/445 is closed

• Comment, document, and clean the code
