I found A way to implement Just in time decryption into my stager project for redteaming. All just in time decryptors I found either decrypted the payload instruction after instruction (which is incredibly slow) or completely in total at start of payload execution (which gives basically no benefit).
Lucky-Spark decrypts a sliding windows of memory pages to keep performance high and still provide protection against memory detection and reverse engineering.
I want to share my code here to maybe help you with your pentest or readteaming project or to show you how to encrypt your "legitimate" project to secure your intellectual property.
The project is not vibe coded and can be found here:
