Provenance

Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures gitHead linked

Without SLSA provenance there is no cryptographic link between this tarball and the public source, so a manually published version cannot be tied back to a reviewed commit.

Accepted risks

Findings the reviewer chose to accept rather than block on.

SourceRuleReasonAccepted byWhen
bogus-package bogus-package AI (bogus-package): Official Microsoft CLI tool; README/repo metadata gaps are not malware indicators. ai
source-diff net-exec-file:dist/client/static/js/main.2e17afb4.js AI (source-diff): Bundled React app makes normal network calls; no exfil behavior found. ai
source-diff obfuscated-file:dist/client/static/js/main.2e17afb4.js AI (source-diff): Webpack-bundled client JS from documented build pipeline, not obfuscation. ai
maintainer-change maintainer-added AI (maintainer-change): microsoft-oss-releases is consistent with official Microsoft release tooling. ai
source-diff obfuscated-file:dist/client/static/js/main.f15b5fe9.js AI (source-diff): Webpack-bundled client build, not obfuscation; standard minified React output. ai
source-diff net-exec-file:dist/client/static/js/main.f15b5fe9.js AI (source-diff): Bundled frontend JS naturally contains fetch+eval-like patterns; no malicious behavior evidenced. ai
source-diff obfuscated-file:dist/client/static/js/main.3261a77b.js AI (source-diff): Standard webpack production bundle (content-hashed SPA output); minification is expected for this package. ai
source-diff net-exec-file:dist/client/static/js/main.3261a77b.js AI (source-diff): Network calls + dynamic code in a bundled React SPA are normal; no dropper pattern present. ai

v0.2.23

3 findings
HIGH New obfuscated file: dist/client/static/js/main.f15b5fe9.js source-diff

Newly added source file contains lines over 3000 chars, suggesting minified or obfuscated code. New obfuscated files are a strong attack indicator.

HIGH New file with network + code execution: dist/client/static/js/main.f15b5fe9.js source-diff

Newly added file contains both network calls and dynamic code execution. This is a hallmark of dropper/loader malware.

LOW No provenance attestation provenance

Package was published without Sigstore provenance. Consider requesting the maintainer enable provenance via CI/CD.

v0.2.22

1 finding
LOW No provenance attestation provenance

Package was published without Sigstore provenance. Only ~12% of npm packages have provenance, so this is common but not ideal.
