Overview
This tool provides a Python module and command line tool that will extract passwords from BPFDoor samples.
The Elastic Security Team has released an indepth analysis of the BPFDoor malware and created an additional tool that will scan for BPFDoor infected hosts.
Getting Started
Docker
We can easily run the extractor with Docker, first we need to build the image.
Building the BPFDoor Docker image
docker build . -t bpfdoor-extractor
Then we run the container with the -v flag to map a host directory to the Docker container directory that contains the BPFDoor samples.
Running the BPFDoor Docker container
docker run -ti --rm -v $(pwd)/binaries:/binaries \
bpfdoor-extractor:latest -d /binaries/
We can either specify a single sample with -f option or a directory of samples with -d
BPFDoor Configuration Extractor help output
docker run -ti --rm bpfdoor-extractor:latest -h

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
bpfdoor-extractor --help
Once that works, you can do the same sort of things as mentioned in the Docker instructions above.
