bigops-timeline-ui@35.5.8

Analysis

bigops-timeline-ui is a trojanized "UI toolkit" that downloads and executes a remote binary on load. When the module is required, it fingerprints the platform/arch and fetches a binary over HTTPS from three Cloudflare Workers hosts (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe. If those fail it falls back to a DNS-TXT channel that reassembles a base64 payload from TXT records under sdk[.]dl[.]wel1[.]ru / ext[.]dl[.]wel1[.]ru / pkg[.]dl[.]wel1[.]ru / net[.]dl[.]wel1[.]ru. The downloaded binary is written to /tmp/.cache_<hex> (or dotnet_diag_<hex>.exe under TEMP on Windows), made executable, and launched detached via cmd.exe /c start /b (Windows) or /bin/sh -c "<path> &" (Unix). The package ships no real UI functionality; the "telemetry" opt-out env vars are a disguise.
