Analysis

The package's index.js is a benign stub that loads _bridge.js, a multi-stage dropper. On require, _bridge.js fingerprints the host platform/arch and downloads a platform-specific second-stage binary over HTTPS from Cloudflare Workers endpoints (oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe). If HTTPS fails it falls back to a DNS-over-TXT channel under wel1[.]ru (c[.]sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru) that reassembles a base64 payload from TXT records. The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe under Windows TEMP), chmod 755, and executed detached via /bin/sh or cmd.exe /c start /b, so it outlives the parent process. The package also ships a large decoy analytics SDK (lib/telemetry.js) to appear legitimate. The remote binary is fetched and executed on every install/require unless DISABLE_TELEMETRY or ANALYTICS_OPT_OUT is set.
