VS Code extensions use fake image containing a trojan
RL researchers have identified 19 malicious extensions on the VS Code Marketplace — the majority containing a malicious file posing as a PNG.
Provenance Validation
What is provenance validation?
Provenance validation is the process of verifying the origin, development, and authorship of a piece of software. It focuses on confirming the authenticity and traceability of the software supply chain, helping to ensure the code’s origin, integrity, and trustworthiness.
Why validate provenance?
In modern software development, especially within CI/CD and DevOps pipelines, software is often composed of code from multiple contributors, third-party libraries, and automated build systems. Without validating provenance, organizations risk introducing tampered or malicious components — intentionally or unknowingly — into production environments.
Provenance validation protects against software supply chain attacks and is increasingly required by security standards such as SLSA (Supply Chain Levels for Software Artifacts), EO 14028, and NIST SSDF.
How it works
Provenance validation combines multiple checks:
- Build Metadata Analysis: Examines who built the artifact, when, and with what tools
- Code Signing & Hash Verification: Ensures artifacts are unchanged from their original signed state
- SBOM Correlation: Matches components in the software with their declared origin and license
- Secure Logs & Attestations: Uses tamper-evident records (e.g., in-toto, SLSA attestations) to trace the software development lifecycle
Validation can occur at ingestion, before deployment, or as part of procurement workflows.
Business Benefits of Provenance Validation
- Enhances Software Trust: Confirms that software was produced by authorized entities using secure processes
- Prevents Supply Chain Attacks: Detects unexpected build sources or delivery routes
- Supports Regulatory Compliance: Meets requirements in EO 14028, FedRAMP, and SBOM-related frameworks
- Enables Secure Procurement:Validates vendor claims with cryptographic and audit-based proof
Provenance validation vs
Topic | Focus Area | Key Differences |
|---|---|---|
Code Signing Validation | Verifies artifact identity | Provenance includes signing, complete build, and sourcing traceability |
SBOM Management | Tracks components and licenses | Provenance also captures where and how components were built |
Build System Hardening | Secures CI/CD infrastructure | Provenance validation ensures outputs are traceable, not just secure |
Best practices to validate provenance
- Require signed attestations for all build artifacts
- Track all inputs, tool versions, and environments in CI/CD metadata
- Correlate SBOM data with accurate artifact content and runtime behavior
- Enforce provenance checks before software release or acceptance
Use cases
- Vendor Software Intake: Verifying build origin before internal use
- Cloud-Native Software Compliance: Confirming that containers and functions were built securely
- Open-Source Risk Mitigation:Tracing the entire path from contribution to delivery for reused components
Additional considerations
- Leverage tools like SLSA, in-toto, and sigstore to automate provenance enforcement
- Ensure teams are trained to interpret and act on provenance metadata
- Consider integrating provenance validation into runtime trust policies
- Provenance is only as strong as the build security behind it — pair with hardened pipelines
