Windows 11 Network Transparency\n\nA Windows 11 **Network Transparency** tool that passively observes which components talk to the network, when they do it, where they connect, and how much data is exchanged — **without blocking traffic, MITM, or kernel drivers**.\n\n## What it does\n- **ETW-based passive capture** of TCP/UDP events (connect/send/recv) and DNS client events (DNS name correlation currently uses responses).\n- Correlates **PID → process name → service names** (when hosted in `svchost` or service-hosted processes).\n- Best-effort **\"why\" correlation** by checking scheduled tasks that ran near the network burst.\n- Classifies activity into likely categories such as **Windows Update**, **Defender**, **Telemetry**, **Store**, **Time Sync**, or **Other** with a confidence score.\n- Outputs JSONL events for live streaming or recording, and provides a summary report.\n\n## What “why” means here\nThis tool does **best-effort correlation**, not perfect causality. It looks for scheduled tasks that ran within a small time window around a network event and reports them as *related tasks*. That correlation can be useful for investigation, but it does **not** prove the task directly caused the traffic.\n\n## Privacy \u0026 Ethics\n- Local observation only; no data is exfiltrated.\n- No traffic blocking or modification.\n- No TLS interception (no MITM).\n\n## Requirements\n- Windows 11 x64\n- .NET 8 SDK\n- Administrator privileges recommended for full ETW capture\n\n## Build\n```powershell\ndotnet build .\\src\\NetworkTransparency\\NetworkTransparency.csproj\n```\n\n## Run\n### Live mode (structured event stream)\n```powershell\ndotnet run --project .\\src\\NetworkTransparency\\NetworkTransparency.csproj -- live --include-dns\n```\n\n### Record mode (JSONL)\n```powershell\ndotnet run --project .\\src\\NetworkTransparency\\NetworkTransparency.csproj -- record --include-dns --output .\\captures\\network.jsonl\n```\n\n### Summary report\n```powershell\ndotnet run --project .\\src\\NetworkTransparency\\NetworkTransparency.csproj -- summary --input .\\captures\\network.jsonl\n```\n\n## JSONL Event Schema\nEach line contains a single event with these fields:\n- `timestampUtc`\n- `pid`\n- `processName`\n- `user`\n- `serviceNames`\n- `localIp`\n- `localPort`\n- `remoteIp`\n- `remotePort`\n- `protocol`\n- `bytesSent`\n- `bytesRecv`\n- `dnsNames`\n- `sniHost` (best-effort, currently null)\n- `classification`\n- `confidence`\n- `relatedTasks`\n- `notes`\n\n## Limitations\n- Kernel provider requires **Administrator** privileges; without it, you may see partial or no data.\n- DNS correlation is best-effort and may miss cached or encrypted DNS.\n- SNI correlation is not currently implemented (no TLS interception is performed).\n- Scheduled task correlation is a heuristic and may include unrelated tasks.\n\n## Smoke test\nA lightweight PowerShell script generates traffic and demonstrates capture.\n```powershell\n.\\scripts\\smoke-test.ps1\n```\n\n## Repository layout\n```\nsrc/NetworkTransparency   # CLI app\nscripts/                  # smoke test script\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdennishilk%2Fwindows-telemetry-inspector","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdennishilk%2Fwindows-telemetry-inspector","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdennishilk%2Fwindows-telemetry-inspector/lists"}
