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 install hook only stages and checks the package's own native CLI, and the JavaScript shim runs that binary on user invocation. Available binary strings point to TeamMesh service endpoints and a crash-reporting setting; limited native analysis did not establish malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 77.0% - **Started:** 2026-10-30T03:39:19.288Z - **Finished:** 2026-10-30T03:39:55.175Z - **Download time:** 765 ms - **Static scan time:** 161 ms - **AI review time:** 34961 ms - **Total time:** 35887 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 a native CLI and runs it when the user invokes the command. - **Trigger:** Postinstall stages the bundled binary on supported npm Unix installs; later CLI execution requires a user command. - **Impact:** No malicious collection, account action, or unrelated network activity was established from the readable source and binary analysis. - **Review source:** ai\_review - **Reviewed:** 2026-10-30T03:39:55.175Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer checks the staged binary with --version before replacing the JavaScript shim. The shim forwards user arguments to the platform binary. - **Rationale:** The install hook only stages and checks the package's own native CLI, and the JavaScript shim runs that binary on user invocation. Available binary strings point to TeamMesh service endpoints and a crash-reporting setting; limited native analysis did not establish malicious behavior. - **Files touched:** install.js, bin/tm.js, native/\-\/tm - **Network endpoints:** api.teammesh.io, sync.teammesh.io, o4512288884326400.ingest.us.sentry.io ### Review decision - **Verdict:** Clean - **Confidence:** 77.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** The postinstall hook selects a platform-specific binary and stages it as the CLI shim; the visible installer code does not collect project or host data or contact a network., The CLI shim launches the matching bundled native binary with the user's arguments, consistent with the package's stated CLI purpose., The readable binary strings name TeamMesh API and sync endpoints, which fit the package's described service., The binary strings include a Sentry crash-reporting endpoint and a TM\_CRASH\_REPORTS setting; the available static view does not show whether reports are sent by default. - **Evidence against:** The native executable is the main CLI implementation, and the prepared analysis reports that its call graph is incomplete., The installer runs automatically, but only stages and checks the bundled binary before replacing the shim. ## Affected versions and remediation This report applies to teammesh@0.33.0. - Review the evidence and your use of teammesh@0.33.0 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.
