distributorblock@35.8.1

Analysis

distributorblock@35.8.1 is a multi-stage remote binary dropper. On require, setup.js fingerprints the platform and downloads a platform-specific binary from rotating Cloudflare Workers hosts oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, and oob-worker[.]cf102-baf[.]workers[.]dev (paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe), with a DNS-TXT fallback channel via c[.]sdk[.]dl[.]wel1[.]ru (and sdk/ext/pkg/net[.]dl[.]wel1[.]ru). The downloaded payload is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe under TEMP on Windows), chmodded 0755, and launched detached via /bin/sh -c or cmd.exe /c start /b so it outlives the parent. The bundled lib/telemetry.js is a decoy analytics facade; the real behaviour is remote code fetch-and-execute at install time.
