NETWIRE Configuration Extractor
Configuration extraction tool for the NETWIRE malware.
Python script to extract the payload from NETWIRE samples.

The recommended and easiest way to get going is to use Docker. From the directory this README is in, you can build a local container.
docker build . -t netwire_loader_config_extractor
Then we run the container with the -v flag to map a host directory to the docker container directory.
docker run -ti --rm -v $(pwd)/data:/data netwire_loader_config_extractor:latest --help
Running it locally
As mentioned above, Docker is the recommended approach to running this project, however you can also run this locally. This project uses Poetry to manage dependencies, testing, and metadata. If you have Poetry installed already, from this directory, you can simply run the following commands to run the tool. This will setup a virtual environment, install the dependencies, activate the virtual environment, and run the console script.
poetry lock poetry install poetry shell netwire-config-extractor --help
All samples need to be unpacked prior to execution extraction attempts.
Our extractor takes either a directory of samples with -d option or -f for a single sample and then can output parts of the configuration of note, specifically:
- -k : extract the encryption keys
- -c : extract the C2 information
- -s : extract the wide-character strings
- -a : extract the ASCII character strings
docker run -ti --rm -v $(pwd)/data:/data netwire_loader_config_extractor:latest -d "C:\tmp\samples"
You can collect the extracted configurations from the directory you set when running the extractor.
