Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 12 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:** 0.34.1 - **Selected version is latest:** No - **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 install hook only validates and installs a bundled local binary, with no install-time data transfer found. The binary’s Sentry URL and crash-report setting suggest runtime telemetry, but its behavior and disclosure could not be confirmed, so a warning is appropriate. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 72.0% - **Started:** 2026-10-30T15:38:56.117Z - **Finished:** 2026-10-30T15:39:51.449Z - **Download time:** 1019 ms - **Static scan time:** 172 ms - **AI review time:** 54140 ms - **Total time:** 55332 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:** Possible undisclosed runtime crash-report telemetry in the bundled native CLI. - **Trigger:** Potentially when a user runs the native tm CLI; the available binary strings do not establish when reporting occurs. - **Impact:** If enabled, crash information may be sent to Sentry; the information included is unknown. - **Evidence paths:** native/win32-x64/tm.exe - **Review source:** ai\_review - **Reviewed:** 2026-10-30T15:39:51.449Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The binary string view includes a Sentry ingest URL and a TM\_CRASH\_REPORTS marker. The report contents and whether reporting is enabled by default could not be established. - **Rationale:** The install hook only validates and installs a bundled local binary, with no install-time data transfer found. The binary’s Sentry URL and crash-report setting suggest runtime telemetry, but its behavior and disclosure could not be confirmed, so a warning is appropriate. - **Files touched:** install.js, bin/tm.js - **Network endpoints:** api.teammesh.io, sync.teammesh.io, o4512288884326400.ingest.us.sentry.io ### Review decision - **Verdict:** Suspicious - **Confidence:** 72.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest runs install.js as a postinstall hook; that script validates a copied local binary with --version before replacing the CLI shim., The CLI shim forwards the user's arguments to the bundled native binary., The Windows binary’s readable string view contains a Sentry ingest URL and a TM\_CRASH\_REPORTS marker, suggesting crash-report telemetry, though activation and payload are unverified. - **Evidence against:** The readable install hook only stages a bundled binary, checks it locally, and swaps the shim; it shows no network request or collection of user data., The CLI wrapper simply passes command-line arguments to the bundled binary., The binary string view also contains TeamMesh API and sync endpoints consistent with the package’s stated team-connection purpose. ## Affected versions and remediation This report applies to teammesh@0.34.1. - Review the evidence and your use of teammesh@0.34.1 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.
