A global npm install automatically modifies Claude Code's global skill control surface and fetches a remote browser-extension archive. The installed skill is configured to activate on broad troubleshooting language and instruct the agent to execute shell commands. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-09-01T03:28:49.082Z - **Finished:** 2026-09-01T03:29:54.311Z - **Download time:** 504 ms - **Static scan time:** 993 ms - **AI review time:** 63731 ms - **Total time:** 65229 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm install automatically modifies Claude Code's global skill control surface and fetches a remote browser-extension archive. The installed skill is configured to activate on broad troubleshooting language and instruct the agent to execute shell commands. - **Trigger:** Installing the package globally through npm or pnpm. - **Impact:** Future Claude Code conversations can be influenced to execute package-directed troubleshooting commands without a separate user setup action. - **Evidence paths:** package.json, dist/scripts/postinstall.js, dist/skill/SKILL.md - **Review source:** ai\_review - **Reviewed:** 2026-09-01T03:29:54.311Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall global AI-agent skill injection and remote extension download. - **Attack narrative:** The npm postinstall hook activates during a global install. It downloads and extracts a remote extension, then copies a bundled skill into the existing Claude Code global skills directory. The skill is intended to auto-trigger on general MCP problem reports and tells Claude Code to run Bash commands directly. This changes a separate AI-agent control surface without an explicit user-command setup flow. - **Rationale:** This is unconsented install-time mutation of a foreign global AI-agent control surface, combined with an automatic remote payload download. The guard requiring an existing Claude directory does not provide user consent. - **Files touched:** ~/.claude/skills/chrome-mcp-vibemaker-doctor/SKILL.md, ~/.mcp-chrome-vibemaker/extension.zip, ~/Downloads/mcp-chrome-vibemaker-extension-v\ - **Network endpoints:** https://github.com/studioddkk/mcp-chrome-vibemaker/releases/latest/download/chrome-mcp-vibemaker-extension.zip ### 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 script automatically., On global installation, it downloads and extracts an unsigned remote browser extension., The postinstall script copies a package-provided skill into Claude Code's global skills directory without an explicit setup command., That installed skill directs Claude Code to run shell commands automatically for broadly worded user requests. - **Evidence against:** No runtime dependency on this package's own name was found., The inspected MCP runtime endpoints are localhost-only; no credential exfiltration code was found in the reviewed files. ## Public findings ### 1.
