EDR flags your payloads because of high-entropy and staging is not an option? Tune in to the webinar of my colleague Moritz Thomas for his Webinar on how to hide code in the .text section of your binary. Awesome tool and we have gotten some great mileage from it 🥷

You can decrease the entropy pretty easily and store it anywhere you want. Entropy is just a single indicator, that is used as a feature by AI based detection during the STATIC analysis phase. Even if a particular section has high entropy you can still bypass detection because many legitimate applications have high entropy sections.
