Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — An import can publish packages using the user's npm credentials and repeatedly change the project's package name and lockfile without a distinct publish request. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 4.1.3 - **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 module starts a loop that renames the current package and publishes it publicly with the user's npm credentials. Although the README describes running the script directly, importing the package also triggers publishing without a distinct request. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-11-04T09:53:15.458Z - **Finished:** 2026-11-04T09:54:26.734Z - **Download time:** 260 ms - **Static scan time:** 19 ms - **AI review time:** 70996 ms - **Total time:** 71276 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 can rename and repeatedly publish the current project to npm under randomized names. - **Trigger:** Module import or execution of \`autopublish.js\`; the publishing function is called at top level. - **Impact:** An import can publish packages using the user's npm credentials and repeatedly change the project's package name and lockfile without a distinct publish request. - **Evidence paths:** package.json, autopublish.js - **Review source:** ai\_review - **Reviewed:** 2026-11-04T09:54:26.734Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script rewrites package metadata, invokes \`npm publish --access public\`, then schedules another publish after a random delay. - **Attack narrative:** The package's main entry points to \`autopublish.js\`, which immediately changes the current package name, publishes it publicly, and schedules another publish. Importing it can therefore use the user's npm credentials to publish randomized package names and modify project metadata without a separate publish request. The README documents running the script directly, but the main entry also makes the behavior reachable through import. - **Rationale:** The main module starts a loop that renames the current package and publishes it publicly with the user's npm credentials. Although the README describes running the script directly, importing the package also triggers publishing without a distinct request. - **Files touched:** package.json, package-lock.json - **Network endpoints:** npmjs.com ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** \`package.json\` sets \`autopublish.js\` as the main module, so requiring the package loads the publishing script., The script changes the current package name to a random value and writes the change to \`package.json\` and \`package-lock.json\`., It runs \`npm publish --access public\` and schedules further publishing after a delay., The script calls \`publishWithDelay()\` at top level, without requiring a separate command or confirmation. - **Evidence against:** The README describes a tool for renaming and publishing packages and tells users to run \`node autopublish.js\` explicitly. ## Affected versions and remediation This report applies to valid\_antlion\_amber-50@4.1.3. - Avoid installing valid\_antlion\_amber-50@4.1.3. 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.
