It also enables a package-controlled MCP launch entry without an explicit setup command. - **Trigger:** npm postinstall when the native prebuild is available - **Impact:** A dependency installation can add or replace MCP launch configuration and alter project files. - **Evidence paths:** package.json, bin/lib/postinstall-prebuilds.mjs, bin/lib/postinstall-host-bootstrap.mjs, bin/lib/install-upgrade.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-05T08:06:54.502Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic consumer-project and AI-agent configuration mutation - **Attack narrative:** The package declares a postinstall hook. When its prebuild is present, that hook creates consumer-project files, then runs an upgrade routine with cleanup enabled. The routine replaces matching Cursor MCP entries and rewrites Codex MCP configuration so those clients launch the package. These mutations happen during dependency installation rather than through the explicit setup commands advertised by the package. - **Rationale:** The confirmed install-time mutation of consumer files and existing AI-agent configuration is a concrete unconsented control-surface change. No exfiltration was needed to establish the install-hook abuse. - **Files touched:** .env, data/, README.md, INSTALL.md, Licence.md, ghostcrab-skills/, .cursor/mcp.json, .cursor/mcp.json.bak, .codex/config.toml, .codex/config.toml.bak ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest runs a postinstall script automatically., Postinstall modifies the consumer project by creating a .env file and data directory., Postinstall invokes an upgrade routine with configuration cleanup enabled., That routine rewrites existing Cursor and Codex MCP configuration to launch this package. - **Evidence against:** No postinstall network endpoint or credential exfiltration was confirmed., The configuration entries are branded for this package and include backup files. ## Public findings ### 1.
