## 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](https://github.com/gentilkiwi/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](https://github.com/SecureAuthCorp/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](#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.
## REQUIREMENTS
* Python 3.6
* impacket >= 0.9.22
* ldap3 >= 2.8.1
* gssapi (Which requires `libkrb5-dev`)

Take a look at the [wiki](https://github.com/the-useless-one/pywerview/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`.
## GLOBAL ARGUMENTS
### LOGGING
You can provide a logging level to `pywerview` modules by using `-l` or `--logging-level` options. Supported levels are:
* `CRITICAL`: Only critical errors are displayed **(default)**
* `WARNING` Warnings are displayed, along with citical errors
* `DEBUG`: Debug level (caution: **very** verbose)
* `ULTRA`: Extreme debugging level (caution: **very very** verbose)
(level names are case insensitive)
### Kerberos authentication
Kerberos authentication is now (partially) supported, which means you can
pass the ticket and other stuff. To authenticate via Kerberos:
1. Point the `KRB5CCNAME` environment variable to your cache credential file.
2. Use the `-k` option in your function call, or the `do_kerberos` in your
library call.
```console
$ klist stormtroopers.ccache
Ticket cache: FILE:stormtroopers.ccache
Default principal: stormtroopers@CONTOSO.COM
Valid starting Expires Service principal
10/03/2022 16:46:45 11/03/2022 02:46:45 ldap/srv-ad.contoso.com@CONTOSO.COM
renew until 11/03/2022 16:43:17
$ KRB5CCNAME=stormtroopers.ccache python3 pywerview.py get-netcomputer -t srv-ad.contoso.com -u stormtroopers -k
dnshostname: centos.contoso.com
dnshostname: debian.contoso.com
dnshostname: Windows7.contoso.com
dnshostname: Windows10.contoso.com
dnshostname: SRV-MAIL.contoso.com
dnshostname: SRV-AD.contoso.com
```
If your cache credential file contains a corresponding TGS, or a TGT for your
calling user, Kerberos authentication will be used.
__SPN patching is partial__. Right now, we're in a mixed configuration where we
use `ldap3` for LDAP commands and `impacket` for the other protocols (SMB,
RPC). That is because `impacket`'s LDAP implementation has several problems,
such as mismanagement of non-ASCII characters (which is problematic for us
baguette-eaters).
`ldap3` uses `gssapi` to authenticate with Kerberos, and `gssapi` needs the
full hostname in the SPN of a ticket, otherwise it throws an error. It would
be possible to patch an SPN with an incomplete hostname, however it's not done
for now.
For any functions that only rely on `impacket` (SMB or RPC functions), you can
use tickets with SPNs with an incomplete hostname. In the following example, we
use an LDAP ticket with an incomplete hostname for an SMB function, without any
trouble. You just have to make sure that the `--computername` argument matches
this incomplete hostname in the SPN:
```console
$ klist skywalker.ccache
Ticket cache: FILE:skywalker.ccache
Default principal: [email protected]
Valid starting Expires Service principal
13/04/2022 14:26:59 14/04/2022 00:26:58 ldap/[email protected]
renew until 14/04/2022 14:23:29
$ KRB5CCNAME=skywalker.ccache python3 pywerview.py get-localdisks --computername srv-ad -u skywalker -k
disk: A:
disk: C:
disk: D:
```
To recap:
| SPN in the ticket | Can be used with LDAP functions | Can be used with SMB/RPC functions |
| :-----------------------------------: | :-----------------------------: | :--------------------------------: |
| `ldap/[email protected]` | ✔️ | ✔️ |
| `cifs/[email protected]` | ✔️ | ✔️ |
| `ldap/[email protected]` | ❌ | ✔️ |
### TLS CONNECTION
You can force a connection to the LDAPS port by using the `--tls` switch. It
can be necessary with some functions, for example when retrieving gMSA
passwords with `get-adserviceaccount`:
```console
$ python3 pywerview.py get-adserviceaccount -t srv-ad.contoso.com -u 'SRV-MAIL$' --hashes $NT_HASH --resolve-sids
distinguishedname: CN=gMSA-01,CN=Managed Service Accounts,DC=contoso,DC=com
objectsid: S-1-5-21-863927164-4106933278-53377030-3115
samaccountname: gMSA-01$
msds-groupmsamembership: CN=SRV-MAIL,CN=Computers,DC=contoso,DC=com
description:
enabled: True
$ python3 pywerview.py get-adserviceaccount -t srv-ad.contoso.com -u 'SRV-MAIL$' --hashes $NT_HASH --resolve-sids --tls
distinguishedname: CN=gMSA-01,CN=Managed Service Accounts,DC=contoso,DC=com
objectsid: S-1-5-21-863927164-4106933278-53377030-3115
samaccountname: gMSA-01$
msds-managedpassword: 69730ce3914ac6[redacted]
msds-groupmsamembership: CN=SRV-MAIL,CN=Computers,DC=contoso,DC=com
description:
enabled: True
```
### JSON OUTPUT
Pywerview can print results in json format by using the `--json` switch.
## 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
* Gracefully fail against Unix machines running Samba
* 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
