The npm package dolyame-ui-postcsscustomproperties version 35.8.1 contains malicious code that, upon being required, downloads and executes a platform-specific binary payload. This payload is fetched from Cloudflare Workers hosts or reconstructed from DNS TXT queries, then saved and executed on the host system. The package uses obfuscation techniques such as string splitting and runtime assembly of module names and hostnames to evade static detection. It masquerades as an analytics or telemetry SDK and typosquats the legitimate postcss-custom-properties package.
