Analysis

On require, dolyame-ui-radio@35.2.2 downloads and executes a remote binary. index.js loads _adapter.js, which fetches a platform-specific payload over HTTPS from oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, and oob-worker[.]cf100-416[.]workers[.]dev (paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe), with a DNS-TXT fallback channel that reconstructs the payload from base64 records under sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, and net[.]dl[.]wel1[.]ru. The downloaded payload is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe under TEMP on Windows), chmod 755, and launched detached via /bin/sh -c "<path> &" or cmd.exe /c start /b. A cache marker is written to /tmp/.analytics_state. The package masquerades as a UI toolkit; the bundled lib/telemetry.js is a decoy analytics module.
