About unblob
unblob scans an arbitrary binary blob, such as a firmware image, for known container formats. It then extracts every archive, file system and compressed stream it finds, including those nested inside one another, so you can look at what the blob contains.
It is aimed at security researchers and engineers who analyse firmware and other opaque binaries, not at everyday ZIP handling. The project is written in Python and Rust. It ships with a Dockerfile and Nix packaging, and includes fuzzing tests and published documentation.
