SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

It helps you plan and execute complex network-layer attack chains (MitM via ARP/IPv6/DNS/DHCP) to force authentication capture and relay across common enterprise protocols.

Core Features & Use Cases

  • LLMNR/NBT-NS/mDNS poisoning & credential capture: Configure Responder to trigger and record NTLM authentication workflows for downstream cracking or relaying.
  • WPAD abuse and DHCPv6 takeover (mitm6): Redirect victim name resolution to a rogue proxy/endpoint to induce forced NTLM auth over IPv6.
  • Relay chaining and credential handling: Select relay targets by signing requirements, analyze NetNTLM hash formats, and decide between cracking vs relay for follow-on actions.

Quick Start

Ask the AI to load the network-protocol-attacks skill and produce a step-by-step execution plan for LLMNR/WPAD poisoning and NTLM relay suitable for a Windows domain on the same broadcast segment.

FAQPage Schema
How do I execute LLMNR and NBT-NS poisoning to capture NTLM hashes?

LLMNR and NBT-NS poisoning intercepts name resolution requests to capture NTLM hashes. You can configure Responder to trigger authentication workflows and record NetNTLM hashes for downstream cracking or relay attacks.

Can I use mitm6 for DHCPv6 takeover and WPAD abuse on a Windows domain?

Yes, mitm6 enables DHCPv6 takeover to redirect victim name resolution to a rogue endpoint. This induces forced NTLM authentication over IPv6, facilitating WPAD abuse and credential relay on Windows domains.

What is the difference between cracking and relaying NetNTLM hashes?

Cracking attempts to recover plaintext passwords from NetNTLM hashes offline, while relaying passes the hash directly to target systems for immediate access. Select relay targets by evaluating signing requirements and analyzing hash formats.

How do I perform IDS evasion when chaining NTLM relay attacks?

IDS evasion during NTLM relay chaining requires coordinating post-capture actions to avoid detection. The skill provides decision logic to manipulate network protocols and execute attacks while minimizing intrusion detection system alerts.

Does ARP spoofing work for inducing credential capture across enterprise protocols?

ARP spoofing positions a Man-in-the-Middle to intercept traffic across enterprise protocols. This enables credential capture by poisoning name resolution and forcing authentication over common network protocols.

What is needed to set up a network protocol attack for a broadcast segment?

Executing a network protocol attack requires operator-provided target information and context. You must coordinate documented tools and configuration logic to poison name resolution on the same broadcast segment.
