A global npm install automatically configures the package-owned LitClaude Claude Code extension. Its hooks run during Claude sessions and may foreground-update the same package from npm. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 94.0% - **Started:** 2026-08-09T01:44:35.981Z - **Finished:** 2026-08-09T01:45:52.515Z - **Download time:** 767 ms - **Static scan time:** 1592 ms - **AI review time:** 74173 ms - **Total time:** 76534 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm install automatically configures the package-owned LitClaude Claude Code extension. Its hooks run during Claude sessions and may foreground-update the same package from npm. - **Trigger:** Global npm postinstall; later Claude SessionStart or LitClaude management commands. - **Impact:** Changes Claude Code's plugin registry, settings/status line, and hook execution surface; later updates can replace this package-owned extension. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/litclaude-ai.js, plugins/litclaude/hooks/hooks.json, plugins/litclaude/bin/litclaude-hook.js, plugins/litclaude/lib/automatic-update.mjs, bin/update-notifier.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-09T01:45:52.515Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Claude plugin registration, hook installation, settings mutation, and self-update. - **Rationale:** This is not concrete malware, but it performs unprompted first-party AI-agent extension setup at install time and can later self-update through Claude hooks. The package-aligned scope and absence of exfiltration support a warning rather than a block. - **Files touched:** scripts/postinstall.mjs, bin/litclaude-ai.js, plugins/litclaude/hooks/hooks.json, plugins/litclaude/bin/litclaude-hook.js, plugins/litclaude/lib/automatic-update.mjs, ~/.claude/plugins/installed\_plugins.json, ~/.claude/plugins/known\_marketplaces.json, ~/.claude/settings.json, ~/.litclaude - **Network endpoints:** https://registry.npmjs.org/litclaude-ai/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json invokes postinstall., scripts/postinstall.mjs auto-runs install on global npm installs., bin/litclaude-ai.js registers and enables a Claude plugin, statusLine, and settings., plugins/litclaude/hooks/hooks.json installs SessionStart and tool-event hooks., plugins/litclaude/lib/automatic-update.mjs can npm-exec newer versions from a cached registry result. - **Evidence against:** Postinstall is gated to global installs and has environment opt-outs., The install target is the package's own litclaude Claude plugin., Automatic update sanitizes child npm environment and excludes sensitive variables., Registry traffic is limited to litclaude-ai version metadata; no credential harvesting found., No hidden binary payload, eval, or confirmed data-exfiltration chain found in inspected sources. ## Public findings ### 1.
