dolyame-ui-container@35.3.7

Analysis

dolyame-ui-container@35.3.7 masquerades as a UI toolkit but is a multi-stage binary dropper. On load it downloads a platform-specific binary from the mirrors oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, and oob-worker[.]cf102-baf[.]workers[.]dev (path /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe depending on OS/arch), with a fallback that retrieves the payload in base64 chunks via DNS TXT queries to c[.]sdk[.]dl[.]wel1[.]ru / ext[.]dl[.]wel1[.]ru / pkg[.]dl[.]wel1[.]ru / net[.]dl[.]wel1[.]ru. The downloaded binary is written to a hidden temp file (.cache_<hex> on Linux/macOS, dotnet_diag_<hex>.exe on Windows) and executed as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c '<file> &' on Unix). The package contains no UI code — only this downloader-and-execute payload.
