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. A Termux-guarded install hook downloads executable dependencies and modifies the installed Claude Code dependency. Each wrapper invocation also contacts npm and can force a global self-update. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-15T20:23:18.851Z - **Finished:** 2026-09-15T20:24:21.694Z - **Download time:** 506 ms - **Static scan time:** 119 ms - **AI review time:** 62218 ms - **Total time:** 62843 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:** A Termux-guarded install hook downloads executable dependencies and modifies the installed Claude Code dependency. Each wrapper invocation also contacts npm and can force a global self-update. - **Trigger:** Installing the package on Termux ARM64, or running the claude wrapper. - **Impact:** An upstream artifact or later package release can be introduced without a user-pinned update step; no direct secret exfiltration was found. - **Evidence paths:** package.json, postinstall.js, src/auto-update.js, src/patches/path-normalization.js - **Review source:** ai\_review - **Reviewed:** 2026-09-15T20:24:21.694Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Lifecycle download and runtime forced self-update. - **Rationale:** The package has a real guarded lifecycle and supply-chain risk because it installs downloaded artifacts and force-updates itself at runtime. The inspected source shows package-aligned endpoints and no concrete exfiltration, self-dependency, or broad AI-agent configuration mutation. - **Files touched:** node\_modules/@anthropic-ai/claude-code/vendor/ripgrep/arm64-android/rg, node\_modules/@img/sharp-wasm32, tmp/ripgrep.tar.gz, sharp-wasm32.tgz - **Network endpoints:** github.com, registry.npmjs.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs a postinstall script automatically., On Termux ARM64, postinstall downloads and extracts a ripgrep archive, then installs its executable into the Claude Code dependency., The command checks npm for a newer version and performs a forced global reinstall before loading Claude Code., Runtime code creates Claude configuration, commands, and agents directories. - **Evidence against:** Network targets are the npm registry and the ripgrep project's GitHub release URL., The install actions are guarded to Termux/Android and ARM64 where relevant., No self-dependency, credential exfiltration, obfuscated payload, or arbitrary remote code loader was found., OAuth token handling stores encrypted local data with restrictive file permissions. ## Affected versions and remediation This report applies to claude-code-termux@1.0.172. - Review the evidence and your use of claude-code-termux@1.0.172 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.
