Later management commands can fetch a newer package version and execute that version's install flow. - **Trigger:** Global npm installation triggers postinstall; later interactive install, update, or doctor commands can trigger the updater. - **Impact:** The package can persist a plugin and alter Claude Code permissions, registry, marketplace, HUD, and settings without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/litclaude-ai.js, plugins/litclaude/lib/automatic-update.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-30T22:10:17.742Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic Claude configuration mutation and same-package version-selected npm execution. - **Attack narrative:** On a global npm install, postinstall invokes the package's install command. That command copies and enables a Claude plugin, changes the Claude registry and marketplace, and updates global settings. The package also maintains an update mechanism that runs npm with a selected release of litclaude-ai and invokes that release's install command, creating a nested lifecycle path that can replace the Claude control surface. - **Rationale:** This is an unconsented postinstall mutation of a broad AI-agent control surface, combined with a runtime same-package update chain. The source establishes the complete install-hook abuse path even though it does not show secret theft. - **Files touched:** ~/.claude/plugins/cache/litclaude-ai, ~/.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:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs a postinstall hook that invokes its install command during global npm installation., That install command copies a plugin, enables it in Claude Code, and changes global Claude settings., Its automatic updater executes npm with a version-selected release of the same package and then runs its install command., The updater backs up and replaces Claude plugin registry, marketplace, and settings files. - **Evidence against:** The postinstall hook skips ordinary non-global installs, CI, and source checkouts unless forced., The registry request is limited to the npm registry and the updater sanitizes its child environment., No source evidence shows credential collection or exfiltration. ## Public findings ### 1.
