## What it is
Inveigh is a cross-platform .NET IPv4/IPv6 machine-in-the-middle tool for penetration testers, with a primary C# version and a legacy PowerShell version. It performs spoofing attacks and captures hashes/credentials via packet sniffing and protocol-specific listeners for protocols like LLMNR, mDNS, NBNS, DHCPv6, HTTP(S), SMB, LDAP, and WebDAV.

## Use cases
- capture NTLM challenge/response hashes on a Windows network
- spoof LLMNR, mDNS, and NBNS name resolution during a pentest
- run a machine-in-the-middle attack over IPv4 and IPv6
- capture credentials through HTTP, HTTPS, SMB, LDAP, and WebDAV listeners
- perform DHCPv6 and ICMPv6 spoofing attacks
- run credential capture tooling on Linux or macOS with .NET 6

## When to choose
- you are a penetration tester needing an active spoofing and hash capture tool on Windows or cross-platform .NET
- you want both packet sniffing and listener-based capture methods
- you need IPv6 attacks like DHCPv6 and ICMPv6 alongside IPv4 name resolution spoofing

## When to avoid
- you need a passive-only network monitoring tool without spoofing
- you are on Linux/macOS and require packet sniffing, which is Windows-only
- you lack authorization to perform machine-in-the-middle attacks on the target network
