The npm package 'checkout-mobile-legal' version 35.8.8 contains malicious code that downloads and executes opaque binaries from author-controlled Cloudflare Workers subdomains. It uses obfuscation techniques to evade static inspection and employs a DNS-TXT record fallback to bypass HTTP filtering. The package masquerades as telemetry software but effectively acts as a remote code execution dropper, allowing arbitrary code execution on the host system upon installation or import.
