Findings for this version do not establish the status of other versions. AI assessment: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. The inspected JavaScript shows a platform-specific installer and launcher, but does not establish an attack. Because the launched native binaries have material unresolved analysis limits, their behavior cannot be cleared or classified from the available source evidence. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-18T08:54:47.254Z - **Finished:** 2026-10-18T08:55:35.106Z - **Download time:** 1787 ms - **Static scan time:** 149 ms - **AI review time:** 45916 ms - **Total time:** 47852 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 concrete attack is established by the inspected JavaScript, but the native binaries it installs and launches remain behaviorally unresolved. - **Trigger:** Installation through npm on a non-Windows platform with a matching binary, or later invocation of the tm command. - **Impact:** The binaries' effects cannot be determined from the available offline analyses, so malicious behavior is neither established nor ruled out. - **Evidence paths:** package.json, install.js, bin/tm.js, .lpm-inspection-NWsuHU/0-cd82ef323ec1.txt, .lpm-inspection-NWsuHU/1-966af68a65cc.txt, .lpm-inspection-NWsuHU/2-76bf4dd017b1.txt, .lpm-inspection-NWsuHU/3-5d55daeeb05f.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T08:55:35.106Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The install hook runs the selected native binary with --version and replaces the JavaScript shim; the shim launches the native binary with the command arguments. - **Rationale:** The inspected JavaScript shows a platform-specific installer and launcher, but does not establish an attack. Because the launched native binaries have material unresolved analysis limits, their behavior cannot be cleared or classified from the available source evidence. - **Files touched:** install.js, bin/tm.js, native/linux-arm64/tm, native/linux-x64/tm, native/darwin-arm64/tm, native/darwin-x64/tm, native/win32-arm64/tm.exe, native/win32-x64/tm.exe ### Review decision - **Verdict:** Manual Review - **Confidence:** 94.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The package runs install.js during postinstall, with platform and package-manager checks before selecting a binary., The install hook copies the selected binary, runs it with --version, then replaces bin/tm.js; the CLI launches that native binary on invocation., Offline reports leave the Linux and macOS binaries unrecognized and the Windows ARM64 binary unsupported., The Windows x64 report says disassembly exceeded its output limit and native call targets remain uninspected. ## Affected versions and remediation This report applies to teammesh@0.8.1. - Review the evidence and your use of teammesh@0.8.1 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.
