Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — The remote recipient receives identifying information about the machine and package installation. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Data Exfiltration - **Selected version:** 0.0.1 - **Selected version is latest:** No - **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 postinstall hook activates code that collects host and installation metadata and sends it to a hard-coded external endpoint. This establishes an active data exfiltration behavior, so the package should be blocked. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-09T02:45:51.849Z - **Finished:** 2026-10-09T02:46:09.406Z - **Download time:** 255 ms - **Static scan time:** 13 ms - **AI review time:** 17289 ms - **Total time:** 17557 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:** Installation automatically sends host and package location metadata to an external IP address. - **Trigger:** npm postinstall execution of beacon.cjs. - **Impact:** The remote recipient receives identifying information about the machine and package installation. - **Evidence paths:** package.json, beacon.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-09T02:46:09.406Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The beacon collects the hostname, install path, and working directory, then sends them in a POST request to a hard-coded endpoint. - **Attack narrative:** During installation, the postinstall hook runs a beacon that sends the machine hostname and package location details to a hard-coded external IP address. This is automatic external data disclosure. - **Rationale:** The postinstall hook activates code that collects host and installation metadata and sends it to a hard-coded external endpoint. This establishes an active data exfiltration behavior, so the package should be blocked. - **Files touched:** package.json, beacon.cjs - **Network endpoints:** http://185.158.107.175:8787/\_ah/dc ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json runs beacon.cjs automatically during postinstall., beacon.cjs sends a POST to a hard-coded external IP address., The beacon payload includes the machine hostname, install path, and working directory. ## Affected versions and remediation This report applies to wie888r@0.0.1. - Avoid installing wie888r@0.0.1. 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.
