Shai Hulud 2.0 is an advanced supply chain attack on the npm ecosystem, characterized by malicious packages that mimic legitimate dependencies and can steal sensitive data, execute remote code, or create backdoors. The attack is particularly concerning due to its ability to propagate unnoticed through transitive dependencies or outdated references, affecting even well-maintained repositories. Arnica's new SBOM enhancement offers a rapid solution to identify exposure by providing a package-centric view that quickly reveals all repositories and files using the compromised package, thus facilitating swift remediation without the need for complex queries. This tool also maps source code to container images, ensuring security teams can see if a vulnerable package is deployed, thereby closing a major visibility gap in modern supply chain attacks.
