The npm package dolyame-ui-group version 35.9.7 contains malicious code that executes arbitrary binaries on the host system during package load. It downloads executables from obfuscated and anonymous worker.dev domains, writes them to temporary files with misleading names, sets executable permissions, and runs them detached via shell commands. The package also includes a secondary dropper module disguised as an analytics SDK that performs similar actions. Sensitive API calls are obfuscated to evade detection. This behavior results in arbitrary code execution on any system installing this package version.
