The npm package dolyame-ui-portal version 35.3.6 contains malicious code that executes attacker-controlled binaries upon installation or requiring. The malicious payload downloads platform-specific binaries from obfuscated Cloudflare Workers hostnames and a DNS-TXT discovery domain, writes them to temporary directories with disguised filenames, sets executable permissions, and spawns them detached from the main process. The dropper attempts to evade sandbox detection by checking environment variables. A secondary dropper exists but is not currently reachable. This results in remote code execution from non-publisher infrastructure.
