Impacket is a collection of Python classes for working with network protocols. Impacket is focused on providing low-level programmatic access to the packets and for some protocols (e.g. SMB1-3 and MSRPC) the protocol implementation itself. Packets can be constructed from scratch, as well as parsed from raw data, and the object oriented API makes it simple to work with deep hierarchies of protocols. The library provides a set of tools as examples of what can be done within the context of this library.
Grab the latest stable release, unpack it and run python3 -m pip install . (python2 -m pip install . for Python 2.x) from the directory where you placed it. Isn't that easy?
Installing
In order to install the source execute the following command from the directory where the Impacket's distribution has been unpacked: python3 -m pip install . (python2 -m pip install . for Python 2.x). This will install the classes into the default Python modules path; note that you might need special permissions to write there.
Testing
If you want to run the library test cases you need to do mainly three things:
Install and configure a Windows 2012 R2 Domain Controller.
Be sure the RemoteRegistry service is enabled and running.
Configure the dcetest.cfg file with the necessary information
Install tox (python3 -m pip install tox)
Once that's done, you can run tox and wait for the results. If all goes well, all test cases should pass. You will also have a coverage HTML report located at impacket/tests/htlmcov/index.html

Hi all, after generating a golden ticket, I go to try and use the wmiexec.py example with the -k and -no-pass options, but I am getting a strange exception:
ConstraintsIntersection(ConstraintsIntersection(), ConstraintsUnion(SingleValueConstraint(11), SingleValueConstraint(13))) failed at: ValueConstraintError('ConstraintsUnion(SingleValueConstraint(11), SingleValueConstraint(13)) failed at: ValueConstraintError('all of (SingleValueConstraint(11), SingleValueConstraint(13)) failed for "15"',)',) at Integer
Did I generate my ticket incorrectly or something?
Hey, i want to relay authenthication from the client to the server(attacker) but the client not relay the aunthentication. When i allow the SMB share on the client \192.168.43.231. It show the message :
Ok. now i want to test if the client can send the authentication. So if i able to capture it, yes, in that case i can deliver my metasploit_payload.exe to the target machine. But i can't capture the authentication. It show the message below:
Sorry this only a question, because i don't now how to fix it. I read many blog but i'm still can't find a solution.
I'm having an issue with secretsdump.py on a ntds.dit file coming from a Windows Server 2016. When I run secretsdump.py on it:
secretsdump.py -ntds ntds.dit -system SYSTEM LOCAL
It returns the following:

Is it possible that Impacket isn't updated to support the extraction of ntds.dit files from a Windows Server 2016 yet? I can provide all the logs, and debugging data needed (minus the actual ntds.dit and SYSTEM files, obviously).

I have compared pcap from mac/windows while connecting to cifs server using libsmb.py
haven't found any field that is wrong or unexpected.
I have also checked NTLMSSP flags and tried variations to see if there is any unsupported flag. but luck.
I can connect to same cifs servers from windows 7 using smb2.
Any help would be appreciated, where to look or if am i missing any setting on server side.
I'm facing the issue when using relay for LDAPs traffic.

System:
Python 2.7.15+
up to date Kali
up to date impacket
ldap3 tested both 2.5.1 and 2.5.2
Same problem was slightly touched in #514, where @dirkjanm mentioned:
(..) it has something to do with whether the SSL certificates are set correctly on the server. Usually targeting another DC worked
I have access to ~12 AD systems (2012 R2 and 2016), targeting any of them results into this error.
Connections using ldp.exe works well (along with many production calls to some of ADs):
LDAP signing not enabled:
Behavior is that LDAPs service RST connection just after TLS hello is received:
So this is not caused by ntlmrelayx not trusting LDAPs sertificate - it's about LDAPs refusing this TLS hello packet.
What steps will reproduce the problem?
1. Download the 0.9.9.9.9 version
2. run setup.py install
3. run samrdump.py <ip>
What is the expected output? What do you see instead?
The normal smb enumeration info are expected, but it returns:

Original issue reported on code.google.com by [email protected] on 18 Jan 2013 at 1:57
I'm playing with no-pac exploitation recently, the last step is doing a s4u2self request, and we don't need to do s4u2proxy request.
But I found that impacket's getST.py has no support for this, and it doesn't support service modification of the returned TGS ticket.
Even there is a feature called AnySPN in impacket, but it won't work in this special situation
here is the result of smbclient.py before my modification to getST.py
after I made some changes to getST.py, I'm able to get a service ticket with the SPN I specified in the command line
getST.py my.domain/WIN-ER6H1V81DV9 -no-pass -k -dc-ip 192.168.25.177 -impersonate Administrator -alt-service CIFS/WIN-ER6H1V81DV9.my.domain -s4u2self -spn WIN-ER6H1V81DV9 -debug
smbclient.py works just fine
I'm a little bit confused of what are the options for a reflection attack (NTLM auth back to the victim which is different from a general relay attack) on an up-to-date W10 host.
Let me explain what i have understand :
SMB NTLM auth reflect back to SMB is patched since 2008 (MS08-068)
NTLM auth reflect back to SMB (like HTTP => SMB) is patched since 2016. This was the goal of Hot Potato by @breenmachine
DCOM DCE (via BITS) to RPC endpoint (TCP port 135) is still working (RottenPotato by @breenmachine or lonelypotato by @decoder-it)
Ok, but demo of these attacks is always done on the victim's host (loopback @IP). Well, my questions are:
Is it possible to manage these reflection attack (or another) over the local network on an fully update W10 host?
Does Impacket implement these attacks ?
I know that @asolino and @dirkjanm discussed about it in an 2 years old issue (https://github.com/CoreSecurity/impacket/issues/188#issue-170611239) but conclusion was quite unclear for me.
See #1448. I'm not sure how tightly integrated you'd want this to be in impacket, so I opted for a simple compatibility shim. This can of course be changed to a full replacement of the existing ESE implementation.
This should bring a considerable performance improvement to secretsdump. My sample AD with only 3 users already sees an improvement (1s vs 2s), but in the past we've seen domains with over 100k users take less than a minute, whereas the original secretsdump would take >24 hours.
During a client engagement I noticed that, when relaying a valid domain admin account to a domain controller (which has signing disabled) and attempting to dump credentials using secretsdump (default action when -c parameter is not specified), it fails for NTDS dit.
To fix this, I had to run socks and then run secretsdump using --use-vss. Any chance custom parameters can be included in ntlmrelayx when secretsdump is ran?
In Python3.10, the default TLS cipher settings have been set to a more secure level. See: https://bugs.python.org/issue43998
The change makes sense for general users, but Impacket is regularly used to access old Windows computers that present certs signed using MD5 or don't support anything higher than TLSv1.0. Impacket users arguably care more about exploiting weaknesses than requiring super secure TLS settings, so this patch lowers the cipher settings to the lowest value. This is in line with the current behavior of not validating certificates at all.
Note that this will not help if the TLS handshake fails due to certificate issues until this bug is fixed in ldap3: https://github.com/cannatag/ldap3/pull/1067

Tox/Coverage Support added, test cases moved to its own directory. Major overhaul.
Many fixes and improvements in Kerberos, SMB and DCERPC (too much to name in a few lines).
Examples improvements
GetUserSPNs.py: -request-user parameter added. Requests STs for the SPN associated to the user specified. Added support for AES Kerberoast tickets (by @elitest).
services.py: added port 139 support and related options (by @real-datagram).
samrdump.py: -csv switch to output format in CSV added.

GetADUsers.py: Gathers data about the domain's users and their corresponding email addresses. It will also include some extra information about last logon and last password set attributes.
getPac.py: Gets the PAC (Privilege Attribute Certificate) structure of the specified target user just having a normal authenticated user credentials. It does so by using a mix of [MS-SFU]'s S4USelf + User to User Kerberos Authentication.
getArch.py: Will connect against a target (or list of targets) machine/s and gather the OS architecture type installed by (ab)using a documented MSRPC feature.
mimikatz.py: Mini shell to control a remote mimikatz RPC server developed by @gentilkiwi.
sambaPipe.py: Will exploit CVE-2017-7494, uploading and executing the shared library specified by the user through the -so parameter.
dcomexec.py: A semi-interactive shell similar to wmiexec.py, but using different DCOM endpoints. Currently supports MMC20.Application, ShellWindows and ShellBrowserWindow objects. (contributions by @byt3bl33d3r).
getTGT.py: Given a password, hash or aesKey, this script will request a TGT and save it as ccache.
getST.py: Given a password, hash, aesKey or TGT in ccache, this script will request a Service Ticket and save it as ccache. If the account has constrained delegation (with protocol transition) privileges you will be able to use the -impersonate switch to request the ticket on behalf other user.
