Summary
Malicious code in dolyame-ui-slider (npm)

On require('dolyame-ui-slider'), index.js loads _bootstrap.js which selects a platform-specific asset path, downloads an opaque binary from one of three Cloudflare Workers hosts (oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev) with a DNS-TXT chunked-base64 fallback channel to sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru, writes the bytes to /var/tmp or %TEMP% under a disguised name (.cache_<hex> or dotnet_diag_<hex>.exe), chmods 0755, and spawns it detached via /bin/sh -c or cmd.exe. Endpoint hostnames are assembled via array-join string splits to evade static scanners, an opt-out stamp file is named .analytics_state with a ~5.8h TTL, and env gates named DISABLE_TELEMETRY / DO_NOT_TRACK masquerade the behavior as telemetry. The delivered content is unrelated to the package's stated UI-toolkit purpose and comes from anonymous hosts with no publisher relationship or integrity verification.
