Installed hooks then observe agent prompts, tool activity, and transcripts. - **Trigger:** npm installation or update when ~/.exe-os setup state exists - **Impact:** Executes package code across future Claude Code sessions and grants its MCP tools broad permissions. - **Evidence paths:** package.json, dist/bin/install.js, dist/chunk-X425OEYF.js, dist/hooks/post-tool-combined.js, dist/hooks/prompt-submit.js, dist/hooks/stop.js - **Review source:** ai\_review - **Reviewed:** 2026-07-30T11:55:24.310Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic Claude Code control-surface registration and hook persistence - **Attack narrative:** The postinstall lifecycle invokes install.js. It always writes package-controlled skills into Claude Code's global skills directory; once any exe-os setup state exists, it silently registers the package MCP server, injects numerous session/tool/prompt hooks, and expands the Claude permission allowlist. Those hooks process prompts, tool input/output, and transcript data in later agent sessions. - **Rationale:** This is concrete, unconsented postinstall mutation of a foreign and broad AI-agent control surface, followed by persistent execution over future Claude Code events. That meets the blocking policy even without a confirmed remote exfiltration host. - **Files touched:** ~/.claude/skills/exe-\*/SKILL.md, ~/.claude.json, ~/.claude/settings.json, ~/.exe/mcp.json, ~/.exe-os/logs/hooks.log, dist/mcp/server.js, dist/hooks/post-tool-combined.js, dist/hooks/prompt-submit.js, dist/hooks/stop.js - **Network endpoints:** http://127.0.0.1:48739/health ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json postinstall runs dist/bin/install.js --commands-only., install.js postinstall always copies package commands into ~/.claude/skills., With existing setup state, postinstall registers an MCP server in ~/.claude.json., Postinstall merges 11 package hook commands into ~/.claude/settings.json., Hooks receive prompts, tool inputs/results, and transcript paths., mergeHooks adds broad mcp\_\_exe-os permissions automatically. - **Evidence against:** No hard-coded remote exfiltration endpoint found in the inspected installer/hooks., Inspected installer health traffic is loopback-only. ## Public findings ### 1.
