Analysis

On require(), the package fingerprints the host OS and architecture, then downloads a platform-specific binary payload from Cloudflare Workers C2 endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) via HTTPS GET /pkg/package. If the HTTPS download fails, it falls back to a DNS TXT-based chunked data channel via c[.]tin[.]dl[.]well1[.]site. The downloaded binary is written to /var/tmp/.cache_<random> (Linux/macOS) or %TEMP%\dotnet_diag_<random>.exe (Windows) and spawned as a detached background process. A 6-hour cache stamp prevents repeated downloads. The package name impersonates Tinkoff internal naming conventions.
