Less sugar (entropy) for your binaries
SugarFree is an open-source tool designed to analyze and reduce the entropy of a provided PE file.
-red?link=https%3A%2F%2Fgithub.com%2Fnickvourd%2FSugarFree%2Freleases){kind=icon}
SugarFree uses two different techniques (strategies) to reduce the entropy of a PE file:
- zero: Appends null bytes (
0x00) to the end of the file, increasing its size while lowering entropy. - word: Appends random English words in byte format to the end of the file, increasing its size while lowering entropy.
The following list explains the meaning of each SugarFree command:
- info: Calculates the entropy of a PE file and its sections.
- free: Lowers the overall entropy of a PE file.
SugarFree is written in Golang, a cross-platform language, enabling its use on both Windows and Linux systems.
