Setup can modify global AI-agent instruction, skill, and hook files and then use an authenticated hosted API. - **Trigger:** Global npm installation followed by an agent obeying the postinstall instruction. - **Impact:** It can persist package guidance and hooks in Claude and Codex global configuration without a direct user command or verified consent. - **Evidence paths:** package.json, scripts/postinstall.mjs, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-01T21:56:38.733Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Agent-directed setup that writes foreign agent control files and contacts a hosted API. - **Attack narrative:** On global installation, the postinstall script addresses any AI agent consuming package output and orders it to run a browser-based setup. That setup writes package-controlled content into global Claude and Codex instruction, skill, and hook locations, then communicates with the hosted API using bearer authentication. The installer text is designed to bypass the usual agent-to-user handoff, so the control-surface mutation is reached through an install-time social-engineering chain. - **Rationale:** The package combines an automatic lifecycle hook, direct AI-agent instructions to act without a user command, and persistent writes to broad foreign AI-agent control surfaces. This is concrete install-hook abuse rather than ordinary package setup. - **Files touched:** scripts/postinstall.mjs, dist/index.js, ~/.claude/CLAUDE.md, ~/.claude/skills, ~/.claude/settings.json, ~/.codex/AGENTS.md, ~/.codex/skills, ~/.codex/hooks.json - **Network endpoints:** https://api.memgineering.com, memgineering.com ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The install lifecycle runs a package script after installation., The postinstall output tells an AI agent to run setup immediately without presenting the command to its user., The setup command writes guidance and skills into global Claude and Codex control files., The package sends authenticated requests to its hosted API after setup. - **Evidence against:** The postinstall script itself only prints output when globally installed., The setup command exposes a dry-run mode and its network base URL can be overridden. ## Public findings ### 1.
