I want to MITM-attack SSH connections coming through an OpenVPN server, any advice?

I am pen testing a small business that tunnels all employee traffic through an OpenVPN server (running on local infrastructure). I want to perform a MITM attack for SSH traffic running through the OpenVPN server by intercepting traffic leaving the OVPN server and going over external networks to the SSH server(s). Ideally, I will run software alongside the OpenVPN server on that machine.

This is a basic diagram of the network structure, in case it wasn't clear.

Doubts with college project

Hello everyone are new to the subreddit, I am a university student of System Engineering. For the subject of "Networks and computer security" I must perform a "hack" of the Wi-fi network of the old university library with the permission of the director of the school of systems. Due to the fact that I have to present a project about the properties of passwords WPS2-psk I decided to opt for Kali Linux and I am using the tool "aircracking", I think I have followed all the steps but when cracking the password with a dictionary it takes a lot of time the process (I’ve been cracking the password for 5 hours, plus my laptop warms up over time) Do you know why this is taking so long? Excuse me if I ask the "fool" or ambiguous, I’m new to this Kali Linux and hack passwords and take care people.

Spoof emails

Why is it that the main spoofed like Emkei CZ don't work anymore? Is there any good and free methods of sending a spoof mail?

Create the perfect password

The best passwords will thwart brute force and dictionary attacks, but it’s also possible to make them easy to remember.

Koppeling : Adaptive DLL Hijacking / Dynamic Export Forwarding

Koppeling is a demonstration of advanced DLL hijack techniques. It was released in conjunction with the “Adaptive DLL Hijacking” blog post. I recommend you start there to contextualize this code.

This project is comprised of the following elements:

* Harness.exe: The “victim” application which is vulnerable to hijacking (static/dynamic)
* Functions.dll: The “real” library which exposes valid functionality to the harness
* Theif.dll: The “evil” library which is attempting to gain execution
* NetClone.exe: A C# application which will clone exports from one DLL to another
* PyClone.py: A python 3 script which mimics NetClone functionality

The VS solution itself supports 4 build configurations which map to 4 different methods of proxying functionality. This should provide a nice scalable way of demonstrating more techniques in the future.

* Stc-Forward: Forwards export names during the build process using linker comments
* Dyn-NetClone: Clones the export table from functions.dll onto theif.dll post-build using NetClone
* Dyn-PyClone: Clones the export table from functions.dll onto theif.dll post-build using PyClone
* Dyn-Rebuild: Rebuilds the export table and patches linked import tables post-load to dynamically prepare for function proxying

The goal of each technique is to successfully capture code execution while proxying functionality to the legitimate DLL. Each technique is tested to ensure static and dynamic sink situations are handled. This is by far not every primitive or technique variation. The post above goes into more detail.

Example

Prepare a hijack scenario with an obviously incorrect DLL

copy C:\windows\system32\whoami.exe .\whoami.exe
1 file(s) copied.

copy C:\windows\system32\kernel32.dll .\wkscli.dll
1 file(s) copied.

Executing in the current configuration should result in an error

whoami.exe
“Entry Point Not Found”

Convert kernel32 to proxy functionality for wkscli

NetClone.exe –target C:\windows\system32\kernel32.dll –reference C:\windows\system32\wkscli.dll –output wkscli.dll
[+] Done.
whoami.exe
