Each wrapper invocation can force-install and run a newer release of this same lifecycle-enabled package. - **Trigger:** Installing the package on Termux or invoking its claude command. - **Impact:** A registry or download compromise can replace executable code used by the AI CLI without a separate user update action. - **Evidence paths:** package.json, postinstall.js, bin/claude-termux.js, src/auto-update.js - **Review source:** ai\_review - **Reviewed:** 2026-09-16T10:44:52.287Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic remote payload installation and forced self-update. - **Attack narrative:** The npm postinstall hook is automatic. In the Termux branch it fetches archives with curl, extracts them, and installs content into the upstream Claude Code vendor tree and local dependency tree. Separately, the command wrapper contacts the npm registry on every invocation and force-installs the newest release of itself globally, which invokes that release's lifecycle hook before restarting. This creates an unconsented remote update path into a third-party AI command environment. - **Rationale:** The automatic lifecycle mutation of a foreign AI CLI, unverified remote executable installation, and forced self-update form a concrete install-hook abuse chain. No exfiltration is required for this supply-chain takeover risk. - **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:** github.com, registry.npmjs.org ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Its postinstall hook runs automatically and, on Termux, downloads and installs executable or package payloads into the Claude Code dependency., The command wrapper silently checks the npm registry and force-installs a newer release of itself globally before loading Claude Code., The lifecycle script modifies a foreign AI CLI's vendor directory and creates the user's .claude directory without an explicit setup command. - **Evidence against:** The observed endpoints are GitHub releases and the npm registry, not an unrelated collection endpoint., No source code sends environment values, OAuth tokens, or local files over the network. ## Affected versions and remediation This report applies to claude-code-termux@1.0.173. - Avoid installing claude-code-termux@1.0.173. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
