Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Exposes identifying host information and local directory paths to the external recipient. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Data Exfiltration - **Selected version:** 1.2.2 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) Trusted malware advisory MAL-2026-17415 identifies this version as malicious. Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. An automatic installation hook collects identifying host and installation information and transmits it to an external endpoint. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-30T06:10:37.633Z - **Finished:** 2026-09-30T06:11:39.533Z - **Download time:** 780 ms - **Static scan time:** 10 ms - **AI review time:** 61109 ms - **Total time:** 61900 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:** An automatic installation hook collects identifying host and installation information and transmits it to an external endpoint. - **Trigger:** Installing the package with lifecycle scripts enabled, or importing its entrypoint. - **Impact:** Exposes identifying host information and local directory paths to the external recipient. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-30T06:11:39.533Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Top-level code gathers operating system information, encodes it as form data, and sends an HTTPS POST without an opt-in check. - **Attack narrative:** The preinstall hook executes index.js automatically. Its top-level code collects host and installation identifiers, then posts the encoded data to meta.brs.cx. The same behavior runs when the entrypoint is imported. No consent gate restricts this transmission. - **Rationale:** The source establishes automatic collection and external transmission of identifying local information during installation. This concrete data exfiltration supports blocking the package. - **Network endpoints:** meta.brs.cx ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json automatically runs index.js during preinstall., index.js collects the installation directory, home directory, hostname, username, DNS servers, and package metadata., index.js encodes the collected data and sends it by HTTPS POST to meta.brs.cx without a consent gate. - **Evidence against:** The inspected code does not read credential files or execute downloaded payloads. ## Affected versions and remediation This report applies to com.epi.e2e\_test@1.2.2. - Avoid installing com.epi.e2e\_test@1.2.2. 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.
