Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 16 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 0.4.4 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package provides Electron monitoring, but renderer startup silently derives an identifying user ID from page cookies and includes it in telemetry. This is undisclosed identity-bearing runtime telemetry, so the package is suspicious rather than malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-11-02T03:20:52.923Z - **Finished:** 2026-11-02T03:21:46.159Z - **Download time:** 255 ms - **Static scan time:** 1512 ms - **AI review time:** 51468 ms - **Total time:** 53236 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:** Renderer telemetry can include an account identifier silently derived from browser cookies. - **Trigger:** An application initializes the renderer SDK in a page with a matching \`uin\` or \`bilive\_uin\` cookie. - **Impact:** Monitoring events can be correlated with a logged-in account identity. The reviewed source does not show the cookie or an authentication credential being transmitted. - **Evidence paths:** lib/tdemelectron-renderer.cjs, README.md - **Review source:** ai\_review - **Reviewed:** 2026-11-02T03:21:46.159Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Initialization copies the cookie value into \`userId\`; event identity data includes that value as \`user\_id\` and is reported to the configured TDEM service. - **Rationale:** The package provides Electron monitoring, but renderer startup silently derives an identifying user ID from page cookies and includes it in telemetry. This is undisclosed identity-bearing runtime telemetry, so the package is suspicious rather than malicious. - **Network endpoints:** https://dem.rumt-zh.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** Renderer initialization automatically extracts \`uin\` or \`bilive\_uin\` from \`document.cookie\` and assigns it to \`userId\`., The event identity envelope includes configured \`userId\` as \`user\_id\`., The renderer bundle contains the default reporting host \`https://dem.rumt-zh.com\`., The README describes the package as an Electron monitoring SDK and documents renderer initialization with an optional \`userId\`. - **Evidence against:** The package’s stated purpose is collecting Electron application monitoring data., Collection starts when the application initializes the renderer SDK; no install-time reporting hook is declared., Session replay is configured separately in the documented initialization example., I found no source showing that the cookie value itself, credentials, or account actions are sent or performed. ## Affected versions and remediation This report applies to tdem-electron-sdk@0.4.4. - Review the evidence and your use of tdem-electron-sdk@0.4.4 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.
