Navigating the maze of binary obfuscation? Meet the “Donut-Decryptor”, a tool tailored to decode the elusive Donut obfuscation. Dive in to unravel its capabilities and bring clarity to concealed code.

Beyond mere decryption, it’s a spotlight in the shadowy corridors of cybersecurity. A must-have for those battling coded enigmas.

A configuration and module extractor for the donut binary obfuscator.


donut-decryptor checks file(s) for known signatures of the donut obfuscator’s loader shellcode.

If located, it will parse the shellcode to locate, decrypt, and extract the DONUT_INSTANCE structure embedded in the binary, and report pertinent configuration data.

If a DONUT_MODULE is present in the binary it is decrypted and dumped to disk.


donut-decryptor currently requires the separate installation of the chaskey-lts module.


You can install donut-decryptor for usage by navigating to the root directory of the project and using pip:

cd /path/to/donut-decryptor
python -m pip install .

Following installation, a command-line script is available. For usage instructions use:

donut-decryptor --help


The files present in the samples directory are 7z files password protected using the password `infected“, all of which contain donuts which can be decoded using this script.
