The npm package 'pfp-integration-mobile-heading' version 20.7.1 contains malicious code that, upon being required, downloads and executes an attacker-controlled binary. This binary is fetched via obfuscated Cloudflare Workers hosts or a covert DNS-TXT channel, saved under disguised filenames, and executed on the host system. The package falsely advertises device integration functionality but instead compromises the host by executing unauthorized code. Any system with this package installed should be considered fully compromised, and secrets stored on it should be rotated immediately.
