Hunt NTLM/Negotiate information disclosure on internet-reachable IIS/SharePoint/Exchange. Anonymous NTLM Type-2 challenge capture leaks NetBIOS domain, internal DNS forest, computer name, AD timestamp via AV_PAIRS structure. Default Windows-installer hostnames (WIN-XXXXXXXXXXX pattern) signal lazy provisioning. Use when target advertises `WWW-Authenticate: NTLM` or `Negotiate` headers anonymously.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Crown Jewel Targets NTLM info disclosure is a **Medium-severity finding when chained to context** — the leak itself is intentional protocol behavior (RFC-compliant NTLMSSP challenge), but on internet-exposed enterprise infrastructure it provides exact reconnaissance for the next stage of an attack. Highest-value targets: - **Internet-reachable IIS / SharePoint / Exchange / OWA** with dual-auth (Forms + NTLM, or NTLM + Kerberos) - **Citrix NetScaler / VMware Horizon View** internet-facing gateways with NTLM-backed AD auth - **Lync / Skype for Business / Teams On-Prem** edge servers - **WSUS / Windows Update Services** with NTLM-protected admin paths - **CIFS-style fileshare proxies** (HCL Sametime, IBM Notes Domino) that proxy NTLM - **Legacy SharePoint farms** that left NTLM enabled on the public-zone IIS binding **What makes this pay:** - Internal AD domain disclosure (parent-forest mapping, e.g. `customer.parent-corp.example` → tenant inside corporate-AD tree) - Default-Windows-hostname disclosure (`WIN-XXXXXXXXXXX` pattern signals rushed provisioning → likely default service-account passwords) - Timestamp leak (used in NTLMv2 hash cracking acceleration) …

How to install
mdr add novaestellar/novahaku/hunt-ntlm-info@sha256:0e7c40f7d599599dThe line at the top of this page pins the label git:20260926.721cd96, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
