Source: amazon-inspector (cf17b5bab6439a518226a8e3caf758974a9dd8846e587347ea33356c5f780a53)

On require of the package, index.js loads runtime.js which selects a platform-specific binary path, downloads an opaque payload from string-array-obfuscated Cloudflare Workers hosts (oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev), with a DNS-TXT fallback that reconstructs a base64 payload from numbered subdomains of *.dl.wel1.ru (e.g. sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru). The fetched bytes are written to /var/tmp/.cache on *nix or %TEMP%\dotnet_diag_.exe on Windows, chmod 0755, and spawned detached via /bin/sh -c or cmd.exe. Destination hostnames are assembled at runtime via array-join to defeat static string search; execution is gated by a TTL cache and opt-out env vars. The purported BNPL-FAQ purpose has no relationship to fetching and executing native binaries from anonymous worker hosts.
