It then HMAC-signs a forged JWT using the installer's VERCEL_DEPLOYMENT_KEY (`crypto.createHmac('sha256', rawKey).update(header+'.'+payload).digest('base64url')`, index.js:41-44) and sends a request carrying that forged token to iad1.suspense-cache.vercel-infra.com with hardcoded team/project/deployment identifiers belonging to a third party. Installer harm is twofold: (1) the deployment key and cache JWT are written into Vercel build logs, where they may be retained, surfaced in CI artifacts, or shared; and (2) the installer's Vercel account is the one issuing a signature-forging request against Vercel's internal suspense-cache endpoint with another party's IDs, exposing the installer to abuse-policy enforcement. The '[P1216]' tag and hardcoded foreign deployment IDs indicate a research/abuse probe rather than a legitimate Builder.\n\n## Source: ghsa-malware (e149c5b37214e25d4fd07a318603e2b499d5a89bbcecd17d7c03b46eb58b70aa)\nAny computer that has this package installed or running should be considered fully compromised.
