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. LPM treats this as warn-only first-party agent extension lifecycle risk. On Termux, automatic installation downloads and installs external binary/package archives while modifying the upstream Claude Code dependency and creating a Claude configuration directory. Invoking the CLI can also replace the global package with the latest registry release. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-12T13:53:23.255Z - **Finished:** 2026-09-12T13:54:16.220Z - **Download time:** 520 ms - **Static scan time:** 117 ms - **AI review time:** 52327 ms - **Total time:** 52965 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:** On Termux, automatic installation downloads and installs external binary/package archives while modifying the upstream Claude Code dependency and creating a Claude configuration directory. Invoking the CLI can also replace the global package with the latest registry release. - **Trigger:** npm postinstall on Termux ARM64, or running the claude wrapper without the auto-update opt-out. - **Impact:** A registry or release-host compromise could supply code through automatically fetched archives or a later package release; no source evidence shows data exfiltration. - **Evidence paths:** package.json, postinstall.js, src/auto-update.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T13:54:16.220Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Termux-specific installer plus forced self-update. - **Rationale:** The package has a real automatic lifecycle and updater attack surface, including direct archive downloads and writes near an AI-agent installation. The source does not establish malicious intent, secret theft, stealth persistence, or the complete self-dependency lifecycle chain required for blocking. - **Files touched:** node\_modules/@anthropic-ai/claude-code/vendor/ripgrep/arm64-android/rg, .claude, node\_modules/@img/sharp-wasm32 - **Network endpoints:** github.com, registry.npmjs.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs postinstall automatically., On Termux ARM64, postinstall downloads and extracts a ripgrep archive into the upstream Claude Code dependency., Postinstall creates the user's .claude directory and downloads Sharp WASM directly into its node\_modules., Each CLI launch checks npm for a newer package version and globally installs that release with force. - **Evidence against:** All observed network destinations are named public package or upstream release hosts., The install-time actions are guarded to Termux, and the source contains no credential exfiltration or arbitrary remote-code loader., The updater selects only this package's latest registry version and provides an opt-out flag. ## Affected versions and remediation This report applies to claude-code-termux@1.0.168. - Review the evidence and your use of claude-code-termux@1.0.168 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.
