Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — The endpoint receives the machine hostname and package environment paths and runtime version. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Data Exfiltration - **Selected version:** 99.0.1 - **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 unsolicited network transmission during installation, exposing host and environment metadata to an unrelated fixed endpoint. The import side effect provides an additional trigger for the same behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-09T02:45:42.641Z - **Finished:** 2026-10-09T02:46:00.753Z - **Download time:** 1017 ms - **Static scan time:** 73 ms - **AI review time:** 17021 ms - **Total time:** 18112 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 environment metadata to an external endpoint. Importing the package also triggers the beacon. - **Trigger:** npm postinstall, or importing index.js. - **Impact:** The endpoint receives the machine hostname and package environment paths and runtime version. - **Evidence paths:** package.json, beacon.cjs, index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T02:46:00.753Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** beacon.cjs builds a metadata payload and sends it in an HTTP POST to a fixed IP address. - **Attack narrative:** The postinstall hook launches beacon.cjs, which sends machine and package environment metadata to a fixed external IP over HTTP. Importing the package triggers the same beacon. This is active, automatic data exfiltration. - **Rationale:** The package performs unsolicited network transmission during installation, exposing host and environment metadata to an unrelated fixed endpoint. The import side effect provides an additional trigger for the same behavior. - **Files touched:** package.json, beacon.cjs, index.js - **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:** The package runs beacon.cjs automatically from its postinstall lifecycle hook., The beacon uses HTTP to send a POST to a fixed external IP address., The payload includes the machine hostname, package install path, working directory, and runtime version., Importing the package also fires the beacon. ## Affected versions and remediation This report applies to xblaxw@99.0.1. - Avoid installing xblaxw@99.0.1. 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.
