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 launcher silently checks npm for a newer release and globally installs it with force. That reruns the package's postinstall hook, which can alter the installed Claude Code vendor tree and download unverified archives on Termux. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-05T07:21:01.617Z - **Finished:** 2026-09-05T07:22:02.478Z - **Download time:** 509 ms - **Static scan time:** 141 ms - **AI review time:** 60210 ms - **Total time:** 60861 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 launcher silently checks npm for a newer release and globally installs it with force. That reruns the package's postinstall hook, which can alter the installed Claude Code vendor tree and download unverified archives on Termux. - **Trigger:** A user runs the claude or claude-termux command; initial package installation also triggers postinstall. - **Impact:** A future registry release can execute its lifecycle hook and replace support binaries without a separate update command or integrity verification. - **Evidence paths:** package.json, bin/claude-termux.js, src/auto-update.js, postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-05T07:22:02.478Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic self-update through global npm installation plus a Termux-gated install hook. - **Rationale:** This is not proven malware, but automatic forced installation of a new release of the same lifecycle-enabled package creates a concrete self-update supply-chain risk. Termux-specific compatibility logic explains the direct file changes but does not remove that risk. - **Files touched:** node\_modules/@anthropic-ai/claude-code/vendor/ripgrep/arm64-android/rg, src/tmp/ripgrep.tar.gz, node\_modules/@img/sharp-wasm32 - **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 launcher automatically checks for updates whenever its command runs., It fetches the package's latest registry version and globally installs that same package with force, which can trigger a newer release's lifecycle hook., The install hook runs automatically and, on Termux, modifies the Claude Code vendor directory and downloads executable content without an integrity check. - **Evidence against:** The lifecycle actions are guarded to Termux/Android and are structured as compatibility setup for ripgrep and Sharp., No source path sends OAuth tokens, environment values, or local files over the network. ## Affected versions and remediation This report applies to claude-code-termux@1.0.164. - Review the evidence and your use of claude-code-termux@1.0.164 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.
