SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the security risk of unintentional NTLM information disclosure on internet-facing enterprise services, which can reveal sensitive internal Active Directory topology to unauthorized parties.

Core Features & Use Cases

  • Automated Reconnaissance: Probes anonymous endpoints for NTLM/Negotiate authentication headers.
  • AV_PAIR Decoding: Parses Type-2 challenge messages to extract NetBIOS names, DNS forest structures, and server timestamps.
  • Use Case: Use this skill to audit internet-reachable IIS, SharePoint, or Exchange servers to determine if they are leaking internal domain names or default Windows hostnames that could facilitate further credential-based attacks.

Quick Start

Use the hunt-ntlm-info skill to probe the target domain example.com for NTLM information disclosure and decode the resulting AV_PAIR data.

FAQPage Schema
How do I detect NTLM information disclosure on internet-facing IIS servers?▼

Detect NTLM information disclosure on IIS servers by probing anonymous endpoints for NTLM/Negotiate authentication headers. This process captures and parses NTLMSSP Type-2 challenge messages to extract sensitive internal Active Directory topology details.

What data can I extract from NTLMSSP Type-2 challenge messages during a security audit?▼

Extracting NTLMSSP Type-2 challenge messages during a security audit reveals NetBIOS names, DNS forest structures, and server timestamps. This decoded AV_PAIR data exposes internal domain names and default Windows hostnames from enterprise infrastructure.

Can I audit Exchange and SharePoint servers for NTLM authentication leaks?▼

Yes, you can audit Exchange and SharePoint servers for NTLM authentication leaks. The skill probes these internet-reachable web-based enterprise services to map internal Active Directory topology and identify server configuration vulnerabilities.

How do I map internal Active Directory topology from external reconnaissance?▼

Map internal Active Directory topology from external reconnaissance by capturing NTLM handshake data from public-facing enterprise services. Analyzing the decoded Type-2 challenge messages reveals internal domain naming structures and server configurations.

Do I need raw socket capabilities to capture NTLM negotiate headers?▼

Yes, raw socket communication capabilities are required to capture NTLM negotiate headers. Maintaining persistent connections is necessary for successful NTLM handshake analysis and accurate Type-2 challenge message parsing.

Why does my NTLM reconnaissance fail to retrieve DNS forest information?▼

NTLM reconnaissance fails to retrieve DNS forest information when persistent raw socket connections are not maintained. Successful AV_PAIR decoding requires maintaining the connection throughout the entire NTLM handshake analysis process.
