That child uses axios to GET https://api.jsonbin.io/v3/b/6a62bc86da38895dfe879659 and passes the returned \`cookie\` field to \`new Function('require',...)(require)\`, executing attacker-controlled JavaScript on the installer's machine at every \`npm... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 100.0% - **Started:** 2026-08-29T02:35:03.410Z - **Finished:** 2026-08-29T02:35:05.313Z - **Download time:** 529 ms - **Static scan time:** 1373 ms - **AI review time:** Not available - **Total time:** 1903 ms ## Security analysis No additional public attack-surface or AI-review details are available. ## Public findings ### 1.
