Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. On Termux, automatic postinstall modifies the upstream Claude Code installation and creates a global Claude directory. It downloads and installs remote archives without an integrity check, and normal CLI use can globally replace the package with a newer release. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-13T11:02:05.789Z - **Finished:** 2026-09-13T11:03:18.787Z - **Download time:** 512 ms - **Static scan time:** 124 ms - **AI review time:** 72361 ms - **Total time:** 72998 ms The recorded confidence comes from the underlying analysis.

It downloads and installs remote archives without an integrity check, and normal CLI use can globally replace the package with a newer release. - **Trigger:** Installing the package on Termux, then running the claude command. - **Impact:** A registry or release-hosted artifact can become executable in the Claude environment, while the package changes a foreign AI CLI installation and user-level Claude control path without a separate setup command. - **Evidence paths:** package.json, postinstall.js, src/auto-update.js, bin/claude-termux.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T11:03:18.787Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-hook mutation of Claude paths plus unchecked remote artifact installation and global self-update. - **Attack narrative:** A package install on Termux automatically writes into the upstream Claude Code dependency and the user's global Claude directory. Its lifecycle hook downloads, extracts, and installs artifacts without a checksum. On every normal launcher invocation, it checks npm and can globally install a newer package release before loading Claude Code, re-entering the lifecycle path. This creates an unconsented supply-chain control point over a foreign AI-agent installation. - **Rationale:** The automatic lifecycle hook mutates foreign Claude Code and global Claude paths while installing unchecked remote artifacts. The runtime global self-update renews that install-hook path during ordinary CLI use. - **Files touched:** node\_modules/@anthropic-ai/claude-code/vendor/ripgrep/arm64-android/rg, ~/.claude, node\_modules/@img/sharp-wasm32 - **Network endpoints:** https://github.com/BurntSushi/ripgrep/releases/download/14.1.1/ripgrep-14.1.1-aarch64-unknown-linux-gnu.tar.gz, https://registry.npmjs.org/claude-code-termux/latest ### Review decision - **Verdict:** Malicious - **Confidence:** 91.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest runs a postinstall script automatically., On Termux, postinstall downloads and extracts a remote ripgrep archive, then places its executable in the upstream Claude Code vendor directory., The install hook creates the user's global .claude directory., Each claude launch checks npm and globally installs a newer release of this package before restarting., The updater is invoked before the upstream Claude Code CLI is imported. - **Evidence against:** The install-time actions are gated on a Termux environment., Observed network destinations are package-related registries or the ripgrep release host., No source code sends OAuth tokens, API keys, or harvested files over the network. ## Affected versions and remediation This report applies to claude-code-termux@1.0.171. - Avoid installing claude-code-termux@1.0.171. 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.
