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, installation downloads and extracts third-party archives into dependency directories. A normal launcher invocation can automatically replace the globally installed package from npm and restart it. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-04T07:39:36.058Z - **Finished:** 2026-09-04T07:40:39.017Z - **Download time:** 260 ms - **Static scan time:** 160 ms - **AI review time:** 62538 ms - **Total time:** 62959 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, installation downloads and extracts third-party archives into dependency directories. A normal launcher invocation can automatically replace the globally installed package from npm and restart it. - **Trigger:** Installing the package on Termux, or running its claude launcher without the no-auto-update option. - **Impact:** A registry or download compromise can be pulled into the user's CLI without an update confirmation; the install hook also creates Claude-related user state. - **Evidence paths:** package.json, postinstall.js, src/auto-update.js, bin/claude-termux.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T07:40:39.017Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic archive installation and forced global self-update. - **Rationale:** The automatic forced global updater and install-time binary downloads are a concrete supply-chain risk that warrants a warning. The inspected implementation is platform-aligned and contains no confirmed malicious payload or data theft. - **Files touched:** node\_modules/@anthropic-ai/claude-code/vendor/ripgrep/arm64-android/rg, node\_modules/@img/sharp-wasm32, $HOME/.claude - **Network endpoints:** https://github.com/BurntSushi/ripgrep/releases/download/14.1.1/ripgrep-14.1.1-aarch64-unknown-linux-gnu.tar.gz, https://registry.npmjs.org/@img/sharp-wasm32/-/sharp-wasm32-0.34.5.tgz, https://registry.npmjs.org/claude-code-termux/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The postinstall hook runs automatically and, on Termux ARM64, downloads and installs an executable ripgrep binary into the Claude Code dependency., The launcher checks npm for a newer release on every normal invocation, globally installs that release with force, then restarts itself., Install-time setup creates a user .claude directory and mutates files under dependencies. - **Evidence against:** The network destinations are explicit GitHub and npm-registry artifact URLs., The install actions are guarded to the Termux environment and match the wrapper's Android compatibility purpose., No source code sends environment values, OAuth tokens, or local files to a remote endpoint., The manifest declares the upstream Claude Code package as its only runtime dependency. ## Affected versions and remediation This report applies to claude-code-termux@1.0.163. - Review the evidence and your use of claude-code-termux@1.0.163 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.
