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 mutates the Claude Code environment and downloads unsigned auxiliary artifacts. Running the wrapper also performs a self-update check that can install a newer package release globally. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-19T10:00:48.913Z - **Finished:** 2026-09-19T10:01:45.056Z - **Download time:** 500 ms - **Static scan time:** 111 ms - **AI review time:** 55530 ms - **Total time:** 56143 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 mutates the Claude Code environment and downloads unsigned auxiliary artifacts. Running the wrapper also performs a self-update check that can install a newer package release globally. - **Trigger:** npm installation on Termux, or running the claude or claude-termux command. - **Impact:** A future registry release can run its lifecycle hook after an automatic runtime update; the package also creates Claude-related user directories during install/runtime. - **Evidence paths:** postinstall.js, src/auto-update.js, src/patches/path-normalization.js - **Review source:** ai\_review - **Reviewed:** 2026-09-19T10:01:45.056Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic Termux setup plus registry-driven global self-update. - **Rationale:** The package has a concrete, automatic self-update and agent-environment mutation surface, so it should be warned. The inspected source does not establish malware behavior or an unconsented broad control-surface takeover. - **Files touched:** postinstall.js, src/auto-update.js, src/patches/path-normalization.js, node\_modules/@anthropic-ai/claude-code/vendor/ripgrep/arm64-android, node\_modules/@img/sharp-wasm32, .claude, .claude/commands, .claude/agents - **Network endpoints:** github.com, registry.npmjs.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The manifest runs a postinstall hook and installs the official Claude Code package as a dependency., On Termux, the install hook creates the user's .claude directory and downloads and extracts extra binaries into installed package directories., Every invocation of the claude wrapper checks the npm registry and can globally install a newer release of this same package, then relaunch it., The runtime patch creates .claude/commands and .claude/agents directories without an explicit setup command. - **Evidence against:** The observed network destinations are public dependency release and npm registry endpoints; no credential collection or send operation was found., The source contains no obfuscation, evaluator, remote command payload, or write of Claude configuration, commands, or agent definitions. ## Affected versions and remediation This report applies to claude-code-termux@1.0.176. - Review the evidence and your use of claude-code-termux@1.0.176 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.
