ARP + ping discovery, port probing, active fingerprinting (HTTP title, SSH banner, TLS cert, NetBIOS, SNMP), vendor lookup via OUI, and weighted-score device classification. Single portable EXE, ~865 KB zipped, no runtime install required.\n\nPart of [killertools.net](https://killertools.net).\n\n## Features\n\n- Self-installer: launch the EXE to install to `%LOCALAPPDATA%\\Programs\\KillerScan\\` with Start Menu and optional desktop shortcut, or just run it portable with no install\n- ARP cache + parallel ping sweep for fast discovery; second ARP pass after sweep catches phones and devices that block ICMP\n- TCP port scan across 24 common service ports with 200ms timeout\n- Active fingerprinting: HTTP title/Server header, SSH banner, TLS cert subject, NetBIOS name (UDP 137), SNMPv1 sysDescr (UDP 161), ICMP TTL\n- MAC OUI vendor identification against the IEEE registry\n- Weighted-score classifier identifies hypervisors, Windows boxes, Linux servers, printers, NAS, network gear, cameras, IoT, mobile, Home Assistant, and more\n- Right-click to copy IP/MAC/hostname, launch RDP/SSH/browser, or override device type\n- CSV and HTML export\n\n## Requirements\n\n- Windows 10 or 11 (x64)\n- No runtime install. Everything needed is inside the EXE (targets .NET Framework 4.8, which ships with every supported Windows release).\n- Run as admin for best ARP results on some networks\n\n## Download\n\n- Prebuilt binary: \u003chttps://github.com/SteveTheKiller/KillerScan/releases/latest/download/KillerScan.zip\u003e\n- Source (GPL3 corresponding source for this release): \u003chttps://github.com/SteveTheKiller/KillerScan/releases/download/v1.3.0/KillerScan-1.3.0-src.zip\u003e\n\n## Build from source\n\n```powershell\ngit clone https://github.com/SteveTheKiller/KillerScan.git\ncd KillerScan\ndotnet publish -c Release\n```\n\nOutput lands in `bin/Release/net48/publish/`. The publish step produces a single Costura-bundled `KillerScan.exe` plus a versioned `KillerScan-\u003cversion\u003e-src.zip` for GPL3 source distribution.\n\nRequires the .NET 8 SDK or later to build (even though the output targets .NET Framework 4.8).\n\n## Changelog\n\nSee [CHANGELOG.md](CHANGELOG.md).\n\n## How classification works\n\nThe classifier accumulates points from every signal (open ports, OUI vendor, hostname keywords, HTTP title, SSH banner, TLS subject, SNMP description, NetBIOS name, TTL) and picks the highest-scoring type above a threshold. This replaces brittle first-match port rules and avoids false positives like \"my coworker's laptop is a hypervisor because port 2179 is open.\"\n\nSee `Services/NetworkScanner.cs` → `ClassifyDevice` for the scoring table.\n\n## License\n\nGPLv3. See [LICENSE](LICENSE). If you fork, modify, or redistribute KillerScan, your version must also be released under GPLv3 with source available. No exceptions for commercial rebrands.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstevethekiller%2Fkillerscan","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fstevethekiller%2Fkillerscan","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstevethekiller%2Fkillerscan/lists"}
