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-gated native binary replacement and execution path, but does not establish malicious behavior. Because analysis leaves several active binaries materially unresolved, manual review is warranted. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-18T14:36:30.289Z - **Finished:** 2026-10-18T14:37:17.126Z - **Download time:** 1530 ms - **Static scan time:** 155 ms - **AI review time:** 45152 ms - **Total time:** 46837 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:** The postinstall hook can install a native CLI binary, and the CLI runs that binary for user commands. Its behavior could not be resolved from the available offline analysis, so no concrete attack was confirmed. - **Trigger:** Package installation or running the tm CLI on a platform with a shipped binary. - **Impact:** The native program's effects remain unknown, leaving a material gap in the active install and runtime paths. - **Evidence paths:** .lpm-inspection-2ZyWS8/0-f6d36ecef3ab.txt, .lpm-inspection-2ZyWS8/1-7fd50731943c.txt, .lpm-inspection-2ZyWS8/2-4411b0125d45.txt, .lpm-inspection-2ZyWS8/3-fc1469e22883.txt, .lpm-inspection-2ZyWS8/5-c34a036e16ce.txt - **Review source:** ai\_review - **Reviewed:** 2026-10-18T14:37:17.126Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The install hook tests and swaps in the native binary; the CLI shim then passes it the user's arguments. - **Rationale:** The inspected JavaScript shows a platform-gated native binary replacement and execution path, but does not establish malicious behavior. Because analysis leaves several active binaries materially unresolved, manual review is warranted. - **Files touched:** package.json, install.js, bin/tm.js, native/linux-arm64/tm, native/darwin-x64/tm, native/linux-x64/tm, native/win32-arm64/tm.exe, native/win32-x64/tm.exe ### Review decision - **Verdict:** Manual Review - **Confidence:** 88.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json activates install.js through a postinstall hook., install.js tests and replaces the CLI shim with a platform binary when its checks succeed., bin/tm.js launches the selected native binary with the CLI arguments., Offline analysis could not inspect the Linux ARM64, Linux x64, or macOS x64 binaries., The Windows ARM64 analysis could not inspect the artifact; Windows x64 analysis leaves native call targets uninspected., The native binaries are on active install and CLI paths, but their behavior remains unresolved. - **Evidence against:** The install hook gates replacement on platform, npm user agent, binary availability, and a successful --version check., No concrete malicious behavior or network endpoint was established from the inspected source. ## Affected versions and remediation This report applies to teammesh@0.11.0. - Review the evidence and your use of teammesh@0.11.0 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.
