The npm package dolyame-ui-layout version 35.9.8 contains malicious code that, upon being required, downloads and executes a native binary payload from dynamically constructed Cloudflare Workers domains and a fallback DNS-TXT base64 source. The payload is saved to temporary directories with names mimicking system diagnostic files, given executable permissions, and launched detached from the main process. The package hides dangerous API calls and module names via string concatenation and does not verify the authenticity or integrity of the downloaded binary. Execution occurs immediately on module load without any lifecycle hook. No official patch or remediation guidance is provided.
