Chainguard Container for malcontent

Enumerate binary capabilities, including malicious behaviors.

Chainguard Containers are regularly-updated, secure-by-default container images.

Download this Container Image

For those with access, this container image is available on cgr.dev:

docker pull cgr.dev/ORGANIZATION/malcontent:latest

Be sure to replace the ORGANIZATION placeholder with the name used for your organization's private repository within the Chainguard Registry.

Compatibility Notes

The Chainguard's malcontent image provides the official containerized distribution of malcontent, a tool developed and maintained by Chainguard to analyze ELF binaries and container images for malicious behavior and risky capabilities. It runs as a non-root user by default and adheres to Chainguard's security-focused best practices.

Getting Started

You can use the official malcontent image to analyze local binaries or container images with ease:

To analyze a local binary file:

docker run --rm \
    -v $(pwd)/target:/scan \
    cgr.dev/ORGANIZATION/malcontent analyze /scan/binary

To scan a container image for potentially malicious behaviors:

docker run --rm cgr.dev/ORGANIZATION/malcontent --image alpine:latest

To perform a diff between two binaries:

docker run --rm -v $(pwd):/work cgr.dev/ORGANIZATION/malcontent diff /work/binary1 /work/binary2

What are Chainguard Containers?

Chainguard Containers are minimal container images that are secure by default.

In many cases, the Chainguard Containers tagged as :latest contain only an open-source application and its runtime dependencies. These minimal container images typically do not contain a shell or package manager. Chainguard Containers are built with Wolfi, our Linux undistro designed to produce container images that meet the requirements of a more secure software supply chain.

The main features of Chainguard Containers include:

• Minimal design, without unnecessary software bloat
• Daily builds to ensure container images are up-to-date with available security patches
• High quality build-time SBOMs attesting to the provenance of all artifacts within the image
• Verifiable signatures provided by Sigstore
• Reproducible builds with Cosign and apko (read more about reproducibility)

For cases where you need container images with shells and package managers to build or debug, most Chainguard Containers come paired with a -dev variant.

Although the -dev container image variants have similar security features as their more minimal versions, they feature additional software that is typically not necessary in production environments. We recommend using multi-stage builds to leverage the -dev variants, copying application artifacts into a final minimal container that offers a reduced attack surface that won’t allow package installations or logins.
