The npm package bigops-api-customer version 35.8.9 contains malicious code that downloads and executes an OS-specific native binary from obfuscated Cloudflare Workers hosts without verification. This behavior results in arbitrary attacker-controlled code execution on the host system. The package masquerades as a REST API client wrapper, which does not justify downloading native binaries. Systems with this package installed should be considered fully compromised, and all secrets and keys on those systems should be rotated immediately.
