The npm package dolyame-ui-inputsecure version 35.8.1 contains malicious code that, upon requiring the package, downloads and executes attacker-controlled native code on the host system. This is done by fetching a platform-specific executable from obfuscated Cloudflare worker endpoints and fallback domains, decoding it, writing it to a temporary location, setting executable permissions, and spawning it detached. The malicious behavior is hidden using runtime string assembly and duplicated in multiple modules to evade static analysis. This results in remote code execution on the installer's machine.
