[Beginners Tutorial] Create a simple exploit using WeAreDevs API

Create a simple exploit using WeAreDevs API
(Warning - due to Hyperion now being out, WeAreDevs API is currently down. However, the steps should be quite similar if you are using another API, you simply have to call their functions)

---

This tutorial is a tutorial for beginners. This will walk beginners though

• Installing Visual Studio;
• Creating an extremely basic UI for an exploit;
• Adding functionality to it;
• Testing and seeing if it works.

This is part 1 in my soon to be created series of tutorials for beginners in specific.

This is not an official tutorial, I made this out of boredom. This is probably the most detailed tutorial on WRD showing how to start off creating very simple exploits.

Step 0.1 | Getting Visual Studio

---

Visual Studio is most commonly used for creating exploits. I will be using Visual Studio 2022.

 

If you already have either Visual Studio 2019 or 2022 installed, make sure you have the ".NET desktop enviroment" workload installed. You can find this by running Visual Studio Installer, clicking "modify" on your version of Visual Studio and selecting ".NET desktop enviroment".  

 

Step 0.2 | Downloading Visual Studio 2022

---

First, download Visual Studio 2022 from here. Run the executable once downloaded.

 

Once open, click continue.

Wait for the installer to finish downloading and installing itself. Once that is done, a new window will pop up, asking you for workloads you wish to install. Click on ".NET desktop development".

Click "install", and wait patiently for it to install itself.

While waiting, you may want to take the oppotunity to go touch some grass. The installation will take approximately 10 minutes.

Step 0.3 | Creating a new project

---

Congratulations! You downloaded Visual Studio 2022, and it's now up and running. If it isn't running yet, you can always launch it from here or by searching Visual Studio in your searchbar.
https://cdn.discordapp.com/attachments/887688273038811177/907950033293426728/unknown.png

This window is now open. Next, you will create a new project. 
https://cdn.discordapp.com/attachments/887688273038811177/907950241616130058/unknown.png

There will be a new window, showing you a bunch of templates to start from. 
https://cdn.discordapp.com/attachments/887688273038811177/907950530557534248/unknown.png

 

Search "WinForm" (or scroll and find it) and click Windows Form App (.NET Framework)

https://cdn.discordapp.com/attachments/887688273038811177/907950862939336784/unknown.png

 

Make sure you select the right template.

 

After that, click "Next" (located at the bottom right corner). Now, a new window will pop up. Name your new project anything you want, and click "Create". I named mine "FirstExploit".
https://cdn.discordapp.com/attachments/887688273038811177/907951289491669003/devenv_tpRZXByj54.png

Success! You created a new project.

Step 1 | Creating a basic UI for your exploit in WinForms

---

For those nerds looking at this, you may ask "why not WPF?" I personally struggled with WPF as a beginner, and WinForms is way easier for beginners.

You will see this window. 

https://cdn.discordapp.com/attachments/887688273038811177/907951625308622848/devenv_Ph5nUiTr8R.png

If it says that your display is scaled up (or down) to a certain level, click "Restart Visual Studio with 100% scaling". You must do this or your UI will be messed up once you run it. 

 

Afer doing so, you must already be dazed by Visual Studio's horrific light mode. Do not fret! You can change Visual Studio's colour theme by searching up "colour theme" and changing Visual Studio's mode.

Click "Dark", then click "OK" to save your changes.

Now, you will need to create a simple textbox and two buttons. The textbox is where you would paste your script, and the two buttons are for injection and execution, respectively. You will need to have the toolbox open. If it isn't open, click on "View" on the top bar and click "Toolbox". 
https://cdn.discordapp.com/attachments/887688273038811177/907952707434860544/unknown.png

Now we have this open.
https://cdn.discordapp.com/attachments/887688273038811177/907952812376326144/unknown.png

Search "RichTextBox", and slide it into anywhere in your window.
https://cdn.discordapp.com/attachments/887688273038811177/907953073266229318/unknown.png

You can resize the RichTextBox by clicking on it once.
https://cdn.discordapp.com/attachments/887688273038811177/907953386433957948/unknown.png

Add in buttons by searching "Button" and dragging it into your window.

https://cdn.discordapp.com/attachments/887688273038811177/907953528977358929/unknown.png

 

Do this twice in order to add two buttons. Resize it as you wish. It might look like this after
https://cdn.discordapp.com/attachments/887688273038811177/907953852324667442/devenv_UDkakCtv9w.png

 

My buttons are rounded since I'm on Windows 11, so don't worry if it isn't rounded for you. Now, resize the window by clicking on it once and resizing it.
https://cdn.discordapp.com/attachments/887688273038811177/907954173746745344/unknown.png

It probably looks something like this now.
https://cdn.discordapp.com/attachments/887688273038811177/907954307205328896/unknown.png

Next, we will add text to the buttons. Click the first button you put in. In the properties window located in your right side, find the text value and change the text from "button1" to "Inject".
https://cdn.discordapp.com/attachments/887688273038811177/907954703353126942/unknown.png

Do the same for the second button you added, but name this "Execute".
https://cdn.discordapp.com/attachments/887688273038811177/907956018619777064/unknown.png

We now have a UI set up! Now we will start to turn this window functional.

 

Step 2 | Referencing WeAreDevs API

---

You will first need to download WeAreDevs API from here. We will be using the C# version, not the C++ version.

 

Windows Security will detect this as a virus. As we all know, WeAreDevs isn't a virus, the way it behaves triggers such kind of detection. You can simply disable Windows Security by opening Virus & Threat Protection and disabling everything you see in the window.
https://cdn.discordapp.com/attachments/887688273038811177/907949092980809738/ApplicationFrameHost_yoTmDQ9f3c.png

You could also just add the entire downloads folder as an exclusion, but I wouldn't really recommend doing so (if you feel you're stupid enough to download viruses). If you scroll down in the Virus & Threat Protection window, you can find the exclusions button and you can add stuff at your own will.

https://cdn.discordapp.com/attachments/887688273038811177/907949365686042644/ApplicationFrameHost_hcqyumwLSW.png

Once downloaded, reference it in your project. In the "Solution Explorer" window, find "References", right click it, and click "Add reference". 
https://cdn.discordapp.com/attachments/887688273038811177/907956620754034708/unknown.png

Once the reference manager window has opened, click "Browse...", navigate to where you downloaded WeAreDevs_API and click WeAreDevs_API.dll. It is most likely in your download folder. After clicking it, click "Add".
https://cdn.discordapp.com/attachments/887688273038811177/907957416111521832/unknown.png

Click "OK".
https://cdn.discordapp.com/attachments/887688273038811177/907957545195413596/unknown.png

WeAreDevs is now referenced!
