devplatform-spa-plugin-s3-feature-toggle@35.7.1

Analysis

On require, the package runs a multi-stage dropper (lib/_runtime.js). It fingerprints the OS/architecture, then downloads a second-stage binary over HTTPS from Cloudflare Workers hosts oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, and oob-worker[.]cf103-070[.]workers[.]dev (paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe). If the download fails it reconstructs the payload from chunked DNS TXT records under c[.]sdk[.]dl[.]wel1[.]ru. The payload is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in %TEMP% on Windows) and executed as a detached background process. A stamp file (.analytics_state) throttles re-execution.
