Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Publishes packages under the invoking user's npm credentials without a separate request for each publication, potentially flooding the registry and affecting the user's npm account. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 2.4.2 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The main entry starts an unbounded publishing loop on import and repeatedly publishes under generated names using the caller's npm credentials. The README describes manual execution, but the manifest makes this behavior automatic for consumers who load the package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-11-04T09:51:44.897Z - **Finished:** 2026-11-04T09:52:48.632Z - **Download time:** 512 ms - **Static scan time:** 18 ms - **AI review time:** 63204 ms - **Total time:** 63735 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Importing the package triggers repeated public npm publishing under randomly generated package names. - **Trigger:** Module load through the package's main entry, autopublish.js. - **Impact:** Publishes packages under the invoking user's npm credentials without a separate request for each publication, potentially flooding the registry and affecting the user's npm account. - **Evidence paths:** package.json, autopublish.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-11-04T09:52:48.632Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script rewrites package.json and package-lock.json, invokes npm publish --access public, then schedules itself to publish again after a delay. - **Attack narrative:** The package's main entry starts a publishing loop as soon as it is loaded. It assigns the package a random name, updates the lockfile, publishes publicly through npm, and schedules another attempt. This can use the invoking user's npm credentials to make repeated publications without separate confirmation for each one. - **Rationale:** The main entry starts an unbounded publishing loop on import and repeatedly publishes under generated names using the caller's npm credentials. The README describes manual execution, but the manifest makes this behavior automatic for consumers who load the package. - **Files touched:** package.json, package-lock.json - **Network endpoints:** npmjs.com ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package manifest sets autopublish.js as the main entry point., Loading the main file starts publishing at top level, without an explicit function call from the importer., The script changes package.json to a randomly generated name, updates package-lock.json, and runs npm publish --access public., After each publish attempt, it schedules another publish; the entry point starts this loop immediately. - **Evidence against:** The README describes the script as an automatic npm publishing tool and tells users to run it with node autopublish.js., The manifest declares no install or postinstall lifecycle hook. ## Affected versions and remediation This report applies to hushed\_zebra\_green-81@2.4.2. - Avoid installing hushed\_zebra\_green-81@2.4.2. 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.
