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. On Termux, installation fetches and extracts an unsigned dependency archive, and ordinary CLI use can globally replace the package with the latest registry release. The package also creates Claude-related directories as part of compatibility setup. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-11T10:13:40.903Z - **Finished:** 2026-09-11T10:14:34.558Z - **Download time:** 258 ms - **Static scan time:** 160 ms - **AI review time:** 53237 ms - **Total time:** 53655 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 fetches and extracts an unsigned dependency archive, and ordinary CLI use can globally replace the package with the latest registry release. The package also creates Claude-related directories as part of compatibility setup. - **Trigger:** npm installation on Termux, or running the claude wrapper without the no-auto-update opt-out. - **Impact:** A compromised or unexpected registry release can be installed and executed without a separate user update command. - **Evidence paths:** package.json, postinstall.js, src/auto-update.js, bin/claude-termux.js, src/patches/path-normalization.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T10:14:34.558Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic archive installation and forced global self-update. - **Rationale:** The code shows risky automatic package replacement and unchecked archive installation, but the visible destinations and compatibility operations are package-aligned and no concrete theft or covert control hijack is present. This warrants a warning rather than a block. - **Files touched:** node\_modules/@anthropic-ai/claude-code/vendor/ripgrep/arm64-android/rg, node\_modules/@img/sharp-wasm32, .claude, .claude/commands, .claude/agents - **Network endpoints:** registry.npmjs.org, github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The automatic postinstall hook downloads and extracts an external Sharp archive without an integrity check., Each CLI launch checks the npm registry and can force-install a newer global release of this same package, then relaunch it., On Termux, runtime patches create Claude configuration directories and alter the process environment., No source evidence sends tokens, environment values, or local files to an attacker-controlled endpoint. - **Evidence against:** Network destinations are the npm registry and the upstream ripgrep GitHub release., Install-time actions are guarded to Termux, and their stated code paths are compatibility setup., The manifest depends on the upstream Claude Code package; it has no declared dependency on itself., The token helper stores encrypted local data and has no network call. ## Affected versions and remediation This report applies to claude-code-termux@1.0.169. - Review the evidence and your use of claude-code-termux@1.0.169 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.
