Analysis

On require(), the package executes a binary dropper (_runtime.js) that fingerprints the host platform/architecture, then downloads a platform-specific second-stage binary from one of four Cloudflare Workers C2 hosts (oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev) via HTTPS GET to /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe. A DNS-based fallback channel via TXT records at tin[.]dl[.]well1[.]site delivers the payload in chunked base64 segments. The downloaded binary is written to /tmp/.cache_<random> (Linux/macOS) or C:\Windows\Temp\dotnet_diag_<random>.exe (Windows) and spawned as a detached background process. A 6.3-hour cooldown prevents repeated downloads. The package has no repository, no README, and no lifecycle hooks — the dropper runs via a require() call in index.js.
