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 launch contacts the npm registry and, when a newer version exists, force-installs and executes that release globally. The install hook also downloads and installs Termux compatibility artifacts. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-12T09:50:13.593Z - **Finished:** 2026-09-12T09:51:12.804Z - **Download time:** 260 ms - **Static scan time:** 105 ms - **AI review time:** 58845 ms - **Total time:** 59211 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:** A normal CLI launch contacts the npm registry and, when a newer version exists, force-installs and executes that release globally. The install hook also downloads and installs Termux compatibility artifacts. - **Trigger:** Installing the package on Termux, or running either packaged CLI command without the auto-update opt-out. - **Impact:** A future registry release can run its lifecycle code on the user's machine without a separate update command; downloaded install artifacts are not integrity-checked. - **Evidence paths:** package.json, postinstall.js, bin/claude-termux.js, src/auto-update.js, src/patches/path-normalization.js - **Review source:** ai\_review - **Reviewed:** 2026-09-12T09:51:12.804Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic remote artifact installation and self-updating global npm installation. - **Rationale:** The package contains no confirmed theft or destructive payload, but it automatically installs a remotely selected future release of itself and executes unchecked downloaded artifacts. These behaviors warrant a warning rather than a publication block because they are transparent, Termux-oriented compatibility mechanisms and lack evidence of malicious intent. - **Files touched:** node\_modules/@anthropic-ai/claude-code/vendor/ripgrep/arm64-android/rg, node\_modules/@img/sharp-wasm32, ~/.claude, ~/.claude/commands, ~/.claude/agents - **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:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs a postinstall script automatically., On Termux, postinstall downloads, extracts, and enables a ripgrep binary without integrity verification., Every CLI launch checks the npm registry and can force-install a newer release of this same package globally, then relaunch it., Runtime patches create Claude configuration directories and alter process-wide module and child-process behavior. - **Evidence against:** The lifecycle network destinations are fixed GitHub and npm-registry URLs., The install-time actions are limited to Termux detection and compatibility setup., No source sends environment variables, OAuth tokens, or local files to a remote endpoint. ## Affected versions and remediation This report applies to claude-code-termux@1.0.170. - Review the evidence and your use of claude-code-termux@1.0.170 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.
