Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — The external recipient learns identifying information about the machine and package installation context. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Data Exfiltration - **Selected version:** 2.0.1 - **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 package performs automatic external reporting of host identity and installation paths during installation. This is concrete 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:** 98.0% - **Started:** 2026-10-09T02:45:43.117Z - **Finished:** 2026-10-09T02:46:00.952Z - **Download time:** 1014 ms - **Static scan time:** 76 ms - **AI review time:** 16744 ms - **Total time:** 17835 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 server. - **Trigger:** The package's postinstall hook runs during npm installation. - **Impact:** The external recipient learns identifying information about the machine and package installation context. - **Evidence paths:** package.json, beacon.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-09T02:46:00.952Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** beacon.cjs sends a JSON POST to a hard-coded HTTP endpoint with the hostname, install path, working directory, package name, and npm user agent. - **Attack narrative:** On installation, the postinstall hook runs beacon.cjs, which sends machine and installation metadata to a fixed external HTTP endpoint. The inspected code shows no user opt-in or destination selection. - **Rationale:** The package performs automatic external reporting of host identity and installation paths during installation. This is concrete data exfiltration behavior, so the package should be blocked. - **Files touched:** beacon.cjs - **Network endpoints:** http://185.158.107.175:8787/\_ah/dc ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The postinstall hook automatically runs beacon.cjs during installation., beacon.cjs posts to a hard-coded external IP address over HTTP., The request payload includes the machine hostname, install path, and working directory. ## Affected versions and remediation This report applies to xblaxw@2.0.1. - Avoid installing xblaxw@2.0.1. 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.
