Running emp then executes that file. - **Trigger:** Installing the package runs postinstall; invoking emp runs the downloaded executable. - **Impact:** A compromised or replaced release asset can run arbitrary code as the installing user's account. - **Evidence paths:** package.json, scripts/postinstall.js, bin/emp.js - **Review source:** ai\_review - **Reviewed:** 2026-09-01T08:26:12.450Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic remote binary download followed by native process execution. - **Rationale:** The package creates an automatic, unverified remote native-payload path at install time and executes the payload when its CLI is used. This is a concrete supply-chain risk but the visible source does not establish independently malicious payload behavior. - **Files touched:** dist/emp-linux, dist/emp-macos, dist/emp-win.exe, bin/emp.js - **Network endpoints:** github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** The install lifecycle runs a package script automatically., That script downloads a platform executable from the mutable GitHub latest-release URL, without a checksum or signature check., It saves the response as an executable in dist and marks it executable., The CLI launches that downloaded executable with the user's arguments. - **Evidence against:** The downloader targets the package's declared GitHub repository., The visible JavaScript does not harvest credentials, alter agent configuration, or exfiltrate files. ## Public findings ### 1.
