The npm package 'checkout-confirm-pos-order-sms-am' version 35.6.4 contains malicious code that executes attacker-controlled native binaries on the installer's machine. Upon requiring the package, it downloads an opaque binary from obfuscated Cloudflare Workers endpoints or via DNS-TXT fallback from specific domains, writes it to a temporary directory under disguised filenames, sets executable permissions, and spawns it detached from the Node.js process. The package uses string splitting and base64 chunk assembly to evade static detection. This behavior effectively results in remote code execution on the host system.
