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. The postinstall behavior is limited to validating and installing the package's own platform-specific CLI binary, and the launcher runs that binary with the user's arguments. The available evidence does not establish malicious behavior; the native analysis is incomplete and includes a Sentry string whose use could not be confirmed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-31T07:09:23.492Z - **Finished:** 2026-10-31T07:09:57.979Z - **Download time:** 1071 ms - **Static scan time:** 169 ms - **AI review time:** 33246 ms - **Total time:** 34487 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 was identified; the package installs and launches its bundled TeamMesh CLI. - **Trigger:** The postinstall hook runs during installation; the native CLI runs when the user invokes \`tm\`. - **Impact:** No malicious collection or other attack behavior was established from the readable source. Native runtime behavior is only partly inspectable. - **Review source:** ai\_review - **Reviewed:** 2026-10-31T07:09:57.979Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall conditionally replaces the JS shim with the matching bundled binary after a version check. The shim passes user arguments to that binary. - **Rationale:** The postinstall behavior is limited to validating and installing the package's own platform-specific CLI binary, and the launcher runs that binary with the user's arguments. The available evidence does not establish malicious behavior; the native analysis is incomplete and includes a Sentry string whose use could not be confirmed. - **Files touched:** bin/tm.js, bin/tm.js.native - **Network endpoints:** api.teammesh.io, sync.teammesh.io, o4512288884326400.ingest.us.sentry.io ### Review decision - **Verdict:** Clean - **Confidence:** 78.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package is described as a TeamMesh CLI and exposes the \`tm\` command through \`bin/tm.js\`., Postinstall only stages the matching bundled binary for npm on supported non-Windows platforms, checks it with \`--version\`, and replaces the shim; no network or project-data collection appears in the script., The launcher invokes the matching bundled native binary with the user's arguments., The binary analysis lists TeamMesh API and sync hosts, consistent with the package's stated purpose. - **Evidence against:** The native executable analysis is limited and does not establish all runtime behavior., The Windows x64 binary string table contains a Sentry endpoint and \`TM\_CRASH\_REPORTS\`; the strings alone do not establish what is sent or when. ## Affected versions and remediation This report applies to teammesh@0.34.8. - Review the evidence and your use of teammesh@0.34.8 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. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node install.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review.

Public source snippet (untrusted): ```text path = native/win32-arm64/tm.exe kind = native_binary sizeBytes = 9463808 magicHex = [redacted] ``` ### 7. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 80.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 8. Low: No License - **Category:** Manifest - **Confidence:** 80.0% Package manifest does not declare a clear license. ### 9. Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 78.0% - **Path:** package.json - **Public source:** [View source]() The package is described as a TeamMesh CLI and exposes the \`tm\` command through \`bin/tm.js\`. Public source snippet (untrusted): ```json "bin": { "tm": "bin/tm.js" }, "scripts": { "postinstall": "node install.js" }, "files": [ "bin", "native", "install.js", ``` ### 10. Low: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 78.0% - **Path:** install.js - **Public source:** [View source]() Postinstall only stages the matching bundled binary for npm on supported non-Windows platforms, checks it with \`--version\`, and replaces the shim; no network or project-data collection appears in the script. Public source snippet (untrusted): ```javascript if (process.platform === "win32") process.exit(0); if (!(process.env.npm[redacted] ??

Low: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 78.0% - **Path:** bin/tm.js - **Public source:** [View source]() The launcher invokes the matching bundled native binary with the user's arguments. Public source snippet (untrusted): ```javascript const platform = `${process.platform}-${process.arch}`; const binary = path.join(__dirname, "..", "native", platform, process.platform === "win32" ? "tm.exe" : "tm"); if (!fs.existsSync(binary)) { console.error(`tm: no prebuilt binary for ${platform}`); process.exit(1); } const result = spawnSync(binary, process.argv.slice(2), { stdio: "inherit" }); if ``` ### 12.
