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. Running the claude wrapper can fetch the latest package version and globally reinstall it with force. On Termux, installation also downloads compatibility artifacts and changes upstream and Claude directories. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 89.0% - **Started:** 2026-09-13T09:43:26.441Z - **Finished:** 2026-09-13T09:44:24.489Z - **Download time:** 767 ms - **Static scan time:** 118 ms - **AI review time:** 57162 ms - **Total time:** 58048 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:** Running the claude wrapper can fetch the latest package version and globally reinstall it with force. On Termux, installation also downloads compatibility artifacts and changes upstream and Claude directories. - **Trigger:** Run the claude or claude-termux command; Termux postinstall runs during npm installation. - **Impact:** A registry-controlled future release can be installed and executed without a separate update command; install also mutates local tool directories. - **Evidence paths:** package.json, bin/claude-termux.js, src/auto-update.js, postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T09:44:24.489Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic npm self-update and Termux-specific installer mutation. - **Rationale:** This is not proven malware, but automatic forced global self-updates and install-time mutation create a real unresolved supply-chain risk. The network targets are fixed, and no credential theft or arbitrary remote execution was found. - **Files touched:** node\_modules/@anthropic-ai/claude-code/vendor/ripgrep/arm64-android/rg, node\_modules/@img/sharp-wasm32, ~/.claude, tmp/ripgrep.tar.gz, sharp-wasm32.tgz - **Network endpoints:** https://registry.npmjs.org/claude-code-termux/latest, https://registry.npmjs.org/@img/sharp-wasm32/-/sharp-wasm32-0.34.5.tgz, https://github.com/BurntSushi/ripgrep/releases/download/14.1.1/ripgrep-14.1.1-aarch64-unknown-linux-gnu.tar.gz ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The CLI silently checks npm for a newer release whenever the user runs it., A newer release is installed globally with npm --force and then relaunched., The postinstall hook downloads and extracts third-party archives on Termux., Postinstall modifies the upstream Claude Code vendor directory and creates ~/.claude. - **Evidence against:** The manifest has no runtime dependency on its own package name., Network destinations are fixed GitHub and npm registry URLs., No source sends credentials, OAuth tokens, or local files over the network., The code contains Termux-specific compatibility patches rather than concealed payload execution. ## Affected versions and remediation This report applies to claude-code-termux@1.0.166. - Review the evidence and your use of claude-code-termux@1.0.166 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.
