The npm package dolyame-ui-progresscircle (version 35.8.1) is a malicious package that masquerades as a UI progress-circle or monitoring SDK but contains no legitimate functionality. Instead, it unconditionally loads a module that downloads platform-specific executables from hardcoded Cloudflare workers.dev hosts and fallback domains, writes them to temporary directories under decoy names, sets executable permissions, and spawns them detached. The package uses string splitting and base64 encoding to evade static detection. This behavior constitutes malicious code execution upon package import or require.
