The npm package bigops-products-travel version 35.7.1 contains malicious code that downloads and executes a platform-specific binary from attacker-controlled Cloudflare Workers hosts. It uses obfuscated domain names and a DNS TXT-record fallback to reconstruct a base64 payload, which is saved to disguised file paths and executed without verification. This behavior is concealed by environment variable checks and rate limiting based on file modification time. The malicious infrastructure is unrelated to the package's documented purpose.
