Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. This is a user-included browser tracker aimed at the package's own host, gated on a page query parameter, with fetch credentials set to omit and no lifecycle scripts. Obfuscation hides that beacon but does not add install-time mutation, cookie theft, or a second recipient. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-26T07:10:01.931Z - **Finished:** 2026-09-26T07:13:49.439Z - **Download time:** 759 ms - **Static scan time:** 15 ms - **AI review time:** 226733 ms - **Total time:** 227508 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:** No attack surface was established. The only behavior is a page-embedded tracker that sends a fingerprint to the vendor host when a query parameter is present, with cookies omitted and no install hook. - **Trigger:** A site includes tracker.js and the page URL has an \_\_mp\_ulid query parameter. - **Impact:** The vendor receives analytics about that page view. Nothing runs at npm install, and stored secrets are not read or sent. - **Review source:** ai\_review - **Reviewed:** 2026-09-26T07:13:49.439Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script collects screen, navigator, WebGL, audio, battery, and pointer fields and POSTs them as JSON to the Muypil tracker path. - **Rationale:** This is a user-included browser tracker aimed at the package's own host, gated on a page query parameter, with fetch credentials set to omit and no lifecycle scripts. Obfuscation hides that beacon but does not add install-time mutation, cookie theft, or a second recipient. ### Review decision - **Verdict:** Clean - **Confidence:** 84.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json 1.0.5 has no preinstall, install, or postinstall script; the only script is a test echo, and main names tracker.min.js., tracker.js runs only when the page URL contains the \_\_mp\_ulid query value, then POSTs JSON to https://api-v1.muypil.com/tracker/page-events with credentials omit., The body is a browser fingerprint plus pointer metrics; localStorage and sessionStorage are probed with a temporary value and then cleared. - **Evidence against:** The host, path, and credential mode are assembled from a rotated string table, so the beacon is not plain to read., The declared main file tracker.min.js is not in the package, so a normal Node require does not load this script. ## Affected versions and remediation This report applies to @cyberdefenseinc/muypil@1.0.5. - Review the evidence and your use of @cyberdefenseinc/muypil@1.0.5 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
