For an existing exe-os setup it also registers an MCP server, installs broad Claude lifecycle hooks, and grants its MCP tools permission. - **Trigger:** npm installation or update - **Impact:** Package code is invoked across Claude sessions and tool events, with broad package-defined MCP capabilities pre-authorized. - **Evidence paths:** package.json, dist/bin/install.js, dist/chunk-X425OEYF.js, dist/chunk-F55JF43M.js - **Review source:** ai\_review - **Reviewed:** 2026-07-30T11:55:18.314Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall mutation of Claude Code global skills, hooks, MCP, and permissions - **Attack narrative:** Installing the package invokes a postinstall script. It copies Claude skills immediately and, when prior setup state exists, modifies Claude’s global MCP configuration and settings to execute package hook programs for numerous agent events while adding allow-list permissions for its tools. These unconsented install-time writes target a foreign, broad AI-agent control surface. - **Rationale:** Source inspection confirms the concrete install-time Claude Code control-surface mutation required for blocking. The scanner’s credential-exfiltration label is not independently confirmed, but is unnecessary to the verdict. - **Files touched:** package.json, dist/bin/install.js, dist/chunk-X425OEYF.js, ~/.claude/skills, ~/.claude.json, ~/.claude/settings.json, ~/.exe/mcp.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall: install.js --commands-only., install.js postinstall copies skills into ~/.claude/skills., If ~/.exe-os setup state exists, postinstall registers MCP and merges hooks., chunk-X425OEYF.js adds hooks for prompts, sessions, tool use, and compaction., chunk-X425OEYF.js expands ~/.claude/settings.json permissions for many exe-os MCP tools., Postinstall writes package-controlled commands into Claude Code’s global control surface. - **Evidence against:** The flagged cloud calls in chunk-F55JF43M.js occur in interactive setup and target api.askexe.com., No confirmed postinstall credential harvesting or remote payload download was found., The optional model URL is environment-provided and SHA-256 checked. ## Public findings ### 1.
