Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. An automatic install hook removes a consumer-project directory unrelated to the package's own destination. It then obtains and runs a binary from a configurable repository. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-28T20:44:43.720Z - **Finished:** 2026-09-28T20:45:25.117Z - **Download time:** 252 ms - **Static scan time:** 18 ms - **AI review time:** 41127 ms - **Total time:** 41397 ms The recorded confidence comes from the underlying analysis.

It then obtains and runs a binary from a configurable repository. - **Trigger:** npm installation triggers the postinstall hook. - **Impact:** Installation can destroy consumer vendor content and execute a binary obtained from an operator-configurable source. - **Evidence paths:** package.json, lib/install.js, lib/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-28T20:45:25.117Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook derives the consumer root from INIT\_CWD, recursively deletes vendor there, and invokes the configured binary downloader. - **Attack narrative:** On installation, the package executes an installer that resolves the consuming project's root and recursively deletes its vendor directory. This deletion is inconsistent with the package's binary destination, which is under the package itself. The installer then downloads and runs a Hugo binary; its repository prefix can be supplied through environment or project configuration. Together, the automatic destructive mutation and configurable binary source create a concrete install-time supply-chain attack surface. - **Rationale:** The postinstall hook deletes consumer-project data without a package-aligned need, then executes a downloaded binary. This is concrete destructive install-time behavior, not ordinary wrapper setup. - **Files touched:** vendor - **Network endpoints:** https://github.com ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package automatically runs its installer after installation., The installer targets the consumer working directory and recursively removes its vendor directory before running the binary setup., Download repository selection accepts environment or project configuration, then constructs a release URL from that value. - **Evidence against:** The default download host is GitHub and the package identifies itself as a Hugo binary wrapper. ## Affected versions and remediation This report applies to hugo-bin@0.165.0. - Avoid installing hugo-bin@0.165.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
