The fhirproxy-utils npm package version 1.0.8 contains malicious code that performs extensive reconnaissance and data exfiltration upon installation and usage. It collects sensitive environment details including host information, user data, network configuration, git identity, CI/CD environment variables, and cloud instance metadata. The stolen data is encoded and exfiltrated to a Cloudflare Workers command-and-control endpoint. The package also masquerades as common build tools to evade detection. Any system with this package installed should be considered fully compromised.
