On an existing exe-os setup it installs a package MCP server, broad event hooks, and MCP permissions; it also unconditionally drops skills. - **Trigger:** npm install/update executes postinstall - **Impact:** Package code executes across future Claude Code prompts, tool calls, sessions, and agent events. - **Evidence paths:** package.json, dist/bin/install.js, dist/chunk-QVM5KATG.js, dist/hooks/post-tool-combined.js, dist/hooks/prompt-submit.js - **Review source:** ai\_review - **Reviewed:** 2026-07-30T11:53:06.036Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall writes Claude skills, MCP configuration, hooks, permissions, and instructions - **Attack narrative:** Installing the package automatically executes its installer. It writes package-controlled skills into Claude Code’s global skills directory; if prior exe-os state exists, it registers an MCP server, injects commands for numerous Claude hook events, and adds allowlisted MCP capabilities. Its installer also inserts rules into the global Claude instructions stating they override default behavior. This is an unconsented install-time mutation of a broad foreign AI-agent control surface. - **Rationale:** The lifecycle path establishes persistent, user-wide Claude Code execution and instruction control without an explicit setup command. This meets the blocking policy regardless of otherwise user-configured runtime networking. - **Files touched:** package.json, dist/bin/install.js, dist/chunk-QVM5KATG.js, ~/.claude/skills/exe-\*/SKILL.md, ~/.claude.json, ~/.claude/settings.json, ~/.claude/CLAUDE.md, ~/.exe/mcp.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json postinstall runs install.js automatically., install.js always copies package commands into ~/.claude/skills., For existing setup, postinstall registers an MCP server and hooks., chunk-QVM5KATG.js adds hooks for prompts, sessions, tools, and agents., It expands Claude permissions for package MCP tools., Injected CLAUDE.md rules claim to override default behavior. - **Evidence against:** No hard-coded external exfiltration endpoint was confirmed in the install path., The Telegram/SMTP networking in chunk-BVV6NHKQ.js is runtime and user-configured. ## Public findings ### 1.
