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. A global installation automatically modifies Claude Code's settings and installs command files. The package later performs detached self-updates that install another registry release. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-06T03:07:01.339Z - **Finished:** 2026-09-06T03:13:03.608Z - **Download time:** 512 ms - **Static scan time:** 378 ms - **AI review time:** 361379 ms - **Total time:** 362269 ms The recorded confidence comes from the underlying analysis.

The package later performs detached self-updates that install another registry release. - **Trigger:** npm global installation, followed by Claude statusline activity. - **Impact:** Claude Code is configured to execute this package and to permit its Node Bash commands without an explicit setup command. - **Evidence paths:** package.json, dist/postinstall.js, dist/commands/install.js, dist/adapters/claude.js, dist/update.js - **Review source:** ai\_review - **Reviewed:** 2026-09-06T03:13:03.608Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Lifecycle-installed Claude control-surface mutation with silent global self-update. - **Attack narrative:** Installing the package globally triggers its postinstall hook, which runs the installer without an explicit Pinglet setup command. When Claude is detected, the installer changes ~/.claude/settings.json, registers the package as the status-line command, adds Bash permission rules, and writes slash-command files that run its CLI. During later statusline maintenance it checks npm and silently launches a detached global installation of the latest pinglet-cli release, allowing a future release to repeat the lifecycle chain. - **Rationale:** This is an unconsented postinstall mutation of a foreign AI-agent control surface, combined with shell permissions and automatic installation of future releases. The behavior is concrete in source and meets the publish-block boundary. - **Files touched:** ~/.claude/settings.json, ~/.claude/commands/pinglet.md, ~/.claude/commands/pinglet-login.md, ~/.claude/commands/pinglet-logout.md, ~/.pinglet/config.json, ~/.pinglet/update.json, dist/cli.js - **Network endpoints:** https://pinglet.halluci.co.kr, https://registry.npmjs.org/pinglet-cli/latest ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The postinstall hook automatically runs the installer for global npm installs., The installer defaults to Claude integration and invokes the Claude adapter when detected., The adapter replaces Claude settings with a Pinglet command and adds Bash allow rules., It creates Claude slash-command files that execute the package CLI through Node., Background refresh checks the npm registry and silently installs a newer global release of this same package. - **Evidence against:** Codex integration requires an explicit --codex option., The inspected network code uses the declared service API and npm registry; no local credential-file harvesting was found., The package scopes its ordinary data files under ~/.pinglet and includes uninstall restoration logic. ## Affected versions and remediation This report applies to pinglet-cli@0.5.4. - Avoid installing pinglet-cli@0.5.4. 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.
