Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. LPM treats this as warn-only first-party agent extension lifecycle risk. Postinstall can refresh exe-os commands and, only after prior exe-os setup, modify Claude Code MCP, hook, and permissions configuration. This creates a persistent package-owned extension surface in Claude Code. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-08-20T15:12:11.286Z - **Finished:** 2026-08-20T15:13:08.407Z - **Download time:** 1268 ms - **Static scan time:** 10158 ms - **AI review time:** 45694 ms - **Total time:** 57121 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Postinstall can refresh exe-os commands and, only after prior exe-os setup, modify Claude Code MCP, hook, and permissions configuration. This creates a persistent package-owned extension surface in Claude Code. - **Trigger:** npm postinstall during installation or update of an already configured exe-os instance. - **Impact:** Claude Code sessions can invoke package hook code and package MCP tools with automatically added permissions. - **Evidence paths:** package.json, postinstall.mjs, dist/bin/install.js, dist/chunk-U45XMFOM.js - **Review source:** ai\_review - **Reviewed:** 2026-08-20T15:13:08.407Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** guarded postinstall MCP/hook registration and daemon-supervision refresh - **Rationale:** The package mutates a foreign AI-agent control surface during postinstall, but only for an existing exe-os setup and with package-aligned MCP/hooks. Treat as a guarded extension lifecycle risk rather than concrete malicious behavior. - **Files touched:** ~/.claude/skills, ~/.claude.json, ~/.claude/settings.json, ~/.exe-os - **Network endpoints:** http://127.0.0.1:48739/health ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** npm postinstall runs the installer in commands-only mode., After a prior setup marker exists, postinstall registers an MCP server, installs Claude Code hooks, and refreshes daemon supervision., Installer rewrites global Claude configuration and adds allow-list entries for its MCP tools. - **Evidence against:** Fresh installs without exe-os setup state return before MCP/hook registration., Inspected installer networking is limited to a localhost daemon health check; no remote download-and-execute path was found., The lifecycle changes are package-aligned and guarded by existing exe-os setup state. ## Affected versions and remediation This report applies to @askexenow/exe-os@0.9.373. - Review the evidence and your use of @askexenow/exe-os@0.9.373 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
