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. A normal CLI invocation can automatically fetch a newer package release and globally reinstall it. On Termux ARM64, that reinstall runs a hook that downloads and installs external binaries into the Claude Code dependency tree. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-26T07:36:07.787Z - **Finished:** 2026-09-26T07:39:08.386Z - **Download time:** 505 ms - **Static scan time:** 125 ms - **AI review time:** 179968 ms - **Total time:** 180599 ms The recorded confidence comes from the underlying analysis.

On Termux ARM64, that reinstall runs a hook that downloads and installs external binaries into the Claude Code dependency tree. - **Trigger:** Running the exported Claude command when auto-update is enabled and a newer registry version exists. - **Impact:** This creates an automatic lifecycle and remote-binary update path. No confirmed data theft or active attack was identified. - **Evidence paths:** package.json, bin/claude-termux.js, src/auto-update.js, postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-09-26T07:39:08.386Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI queries the npm registry, runs forced global npm installation of its own latest release, and the post-install hook downloads and extracts ripgrep or Sharp fallback archives. - **Rationale:** The automatic self-update and lifecycle-driven binary download create a meaningful supply-chain capability. Static inspection found no concrete exfiltration, stealth persistence, or deliberate obfuscation supporting a malicious classification. - **Files touched:** postinstall.js, src/auto-update.js, bin/claude-termux.js - **Network endpoints:** https://registry.npmjs.org/claude-code-termux/latest, https://github.com/BurntSushi/ripgrep/releases/download/14.1.1/ripgrep-14.1.1-aarch64-unknown-linux-gnu.tar.gz, https://registry.npmjs.org/@img/sharp-wasm32/-/sharp-wasm32-0.34.5.tgz ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package declares an automatic post-install script., The exported CLI invokes its update check before loading Claude Code., The update check queries the npm registry for this package's latest release., When newer, the update path globally installs that release with force, which can re-enter its lifecycle hook., On Termux ARM64, the lifecycle hook downloads and extracts an external ripgrep archive into the Claude Code vendor location., OAuth tokens are written only to a local encrypted file with owner-only permissions; no send operation was identified in that patch. - **Evidence against:** The examined network destinations are fixed package-aligned release and registry endpoints, not an operator-configurable recipient., The code is readable and platform-gated; no credential exfiltration, obfuscation, or broad agent-configuration write was found in the inspected paths. ## Affected versions and remediation This report applies to claude-code-termux@1.0.179. - Review the evidence and your use of claude-code-termux@1.0.179 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.
