The remote script is outside the package artifact and can install arbitrary code before its binary is copied into the package bin directory. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-07-20T17:05:50.749Z - **Finished:** 2026-07-20T17:06:11.564Z - **Download time:** 509 ms - **Static scan time:** 10 ms - **AI review time:** 20296 ms - **Total time:** 20815 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm install automatically fetches a remote shell script and executes it. The remote script is outside the package artifact and can install arbitrary code before its binary is copied into the package bin directory. - **Trigger:** Global npm or Bun installation that permits postinstall scripts on non-Windows, non-CI hosts. - **Impact:** Remote server-controlled code executes with the installing user's permissions. - **Evidence paths:** package.json, scripts/install.js, bin/swirls, bin/README.txt, README.md - **Review source:** ai\_review - **Reviewed:** 2026-07-20T17:06:11.564Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time remote shell download and execution - **Rationale:** This is a package-aligned CLI bootstrap, but it creates a real unauthenticated remote-code-execution supply-chain surface during postinstall. No source evidence establishes credential theft, persistence, or another concrete malicious objective. - **Files touched:** scripts/install.js, bin/swirls, ~/.local/bin/swirls - **Network endpoints:** https://swirls.ai/install ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** package.json defines an install-time postinstall hook., scripts/install.js runs \`curl -fsSL https://swirls.ai/install | bash\` via execSync., The downloaded script is unauthenticated and its contents are not packaged for review., The lifecycle script copies the resulting ~/.local/bin/swirls into bin/swirls. - **Evidence against:** The hook exits for CI, Windows, and non-global installs., Source contains no credential harvesting, exfiltration, destructive actions, or AI-agent configuration writes., README.md and bin/README.txt describe the binary-bootstrap behavior. ## Public findings ### 1.
