Files
Keep files secure by requiring users to be logged in and concealing file URL
First, upload your URL to a file host. You could use Discord, make your own CDN using Netlify or GitHub pages so the URL stays the same and the file just changes when you upload new one. Other uploaders include https://pomf.cat and https://catbox.moe
Now, copy the direct download link. This should include the file extension (
.exe, .sys, .dll) at the end of the URL. Paste this URL in your web browser. Make sure that it downloads immediately without you needing to click a button or anything. If you need to click a button or something to download, then it’s the wrong URL and will NOT work.
Navigate to https://keyauth.cc/app/?page=files and click the Upload File button. Paste the direct download link in the URL field and then press the Submit button.
You will then be displayed a File ID, copy this ID and use while invoking the download function in your loader. Here’s a C# code snippet.
Program.cs
1
byte[] result = KeyAuthApp.download("953440");
2
if (!KeyAuthApp.response.success)
3
{
4
Console.WriteLine("\n Status: " + KeyAuthApp.response.message);
5
Thread.Sleep(1500);
6
Environment.Exit(0);
7
}
8
else
9
File.WriteAllBytes(Directory.GetCurrentDirectory() + "\\37065.pdf", result);
The download function returns the bytes of the file. You may utilize these bytes however you’d like. In the code snippet, the bytes are used to write a file to disk. However if you want to make it very difficult for a user to obtain the file being downloaded, you’ll want to keep the bytes in memory and execute the file without writing it to disk. You can find plenty examples of this online on GitHub with the search queries "RunPE" and "injector bytes"
