REMINDer 
Detect packers on executable files using a simple entropy-based heuristic.
REMINDer (REsponse tool for Malware INDication) is an implementation based on this paper into a Python package with a console script to detect whether an executable is packed using a simple heuristic.
lief is used for binary parsing.
$ pip install reminder-detector
$ reminder --help
[...]
usage examples:
- reminder program.exe
- reminder /bin/ls --entropy-threshold 6.9
💡 Detection Mechanism
- Find the EP section
- Check whether it is writable
- If yes, check whether entropy is beyond a threshold (depending on the executable format)
- If yes, the input executable is packed ; otherwise, it is not
