HashiCorp Packer 1.16 Adds Native SLSA Provenance Generation and Verification for Machine Images
HashiCorp has released Packer 1.16, which introduces native support for SLSA provenance generation to enhance supply-chain security for machine images. The update allows users to verify the integrity of build artifacts by tracking commits, pipelines, and identities through standardized attestations.
Why it matters
Improving supply-chain security for machine images is critical for preventing the propagation of tampered software across cloud infrastructure.

The issue with the release targets is clear but important. Machine images support every workload running on them. If an image is tampered with or cannot be verified, it can quietly spread to every instance created from it. Before this release, locating the source of an image required sifting through outdated build logs. Packer didn't have a way to show which commit, pipeline, or identity created a specific artifact.
