The npm package fb-forms-form-boilerplate-contacts (version 20.7.1) contains malicious code that downloads and executes a native binary from attacker-controlled Cloudflare Workers endpoints. This binary is saved to temporary directories with disguised names, given execute permissions, and run detached without any signature verification. The package effectively acts as a dropper, allowing arbitrary code execution with the privileges of the installer. Any system with this package installed should be considered fully compromised, and all secrets on that system should be rotated immediately.
