hunt-ntlm-info skill

by elementalsouls·elementalsouls/Claude-BugHunter·4.7k stars·MIT

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.

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)
  • Direct attack-map enrichment for credential spraying combined with hunt-auth-bypass Legacy-Protocol Matrix

Attack Surface Signals

Response headers signaling NTLM availability:

WWW-Authenticate: NTLM
WWW-Authenticate: Negotiate
WWW-Authenticate: NTLM, Negotiate
WWW-Authenticate: Negotiate, NTLM

URL patterns where NTLM is commonly exposed:

/_api/web/CurrentUser                  (SharePoint REST)
/_vti_bin/*.asmx                       (SharePoint legacy SOAP)
/EWS/Exchange.asmx                     (Exchange Web Services)
/Autodiscover/Autodiscover.xml         (Exchange autodiscover)
/owa/                                  (Outlook Web App)
/Microsoft-Server-ActiveSync           (ActiveSync)
/PowerShell                            (Exchange Mgmt Shell over HTTPS)
/api/v3/                               (TeamCity, Atlassian)
/wsus/                                 (Windows Server Update Services)
/manager/html                          (some Tomcat behind IIS)
/iisstart.htm                          (default IIS, sometimes reveals NTLM upstream)

Tech-stack signals:

  • IIS on the public internet (almost always NTLM-capable, even if Forms is the front)
  • SharePoint Web Front End (almost always dual-auth Forms + NTLM)
  • Exchange edge transport
  • Server header Microsoft-HTTPAPI/2.0, Microsoft-IIS/, IIS/

Step-by-Step Hunting Methodology

  1. Probe every anonymous endpoint for WWW-Authenticate: NTLM. Send a vanilla GET and inspect response headers. If NTLM is offered, proceed.
  1. Send a valid NTLMSSP Type-1 message anonymously. The Type-1 base64 below requests NetBIOS-domain and Workstation info from the server:
Authorization: NTLM TlRMTVNTUAABAAAAB4IIogAAAAAAAAAAAAAAAAAAAAAGAbEdAAAADw==

This is the standard test Type-1 with negotiate flags NTLMSSPNEGOTIATEUNICODE | NTLMSSPNEGOTIATEOEM | NTLMSSPNEGOTIATENTLM | NTLMSSPNEGOTIATEALWAYSSIGN | NTLMSSPNEGOTIATEKEYEXCH | NTLMSSPNEGOTIATE56 | NTLMSSPNEGOTIATE128 | NTLMSSPNEGOTIATETARGET_INFO. The OS Version field (06 01 B1 1D 00 00 00 0F) is Windows 7 build 7601 — accepted by virtually every NTLM responder.

  1. Use a keep-alive raw socket, not Python requests / curl one-shot. Most HTTP libraries close the connection between the Type-1 send and Type-2 reception. Use one of:
  • Burp Repeater with Connection: keep-alive set explicitly
  • Burp mcpburpsendhttp1request (handles keep-alive natively)
  • Python raw socket + ssl.wrap_socket (see Payload section)
  1. Parse the Type-2 challenge from the WWW-Authenticate: NTLM response header. Base64-decode the value. The structure is NTLMSSP per MS-NLMP:
  • Bytes 0-7: literal NTLMSSP\0
  • Bytes 8-11: MessageType = \x02\x00\x00\x00
  • Bytes 12-19: TargetName SecurityBuffer (len, alloc, offset)
  • Bytes 20-23: NegotiateFlags
  • Bytes 24-31: Server Challenge (8 bytes — useful for offline cracking)
  • Bytes 40-47: TargetInfo SecurityBuffer (len, alloc, offset)
  • TargetInfo body: AV_PAIRS array of (AvId u16, AvLen u16, Value)
  1. Decode the AVPAIRS.** The AvIds you care about:
  • 1 = NetBIOS Computer Name
  • 2 = NetBIOS Domain Name
  • 3 = DNS Computer Name (FQDN of the responding server)
  • 4 = DNS Domain Name (the AD domain)
  • 5 = DNS Tree Name (the AD forest root)
  • 7 = Timestamp (FILETIME, useful for NTLMv2 hash relay / cracking)
  • 9 = Target Name (in newer NTLMSSP)
  1. Map findings to severity tier:
  • Internet-exposed + default WIN-XXXXXXXXXXX hostname + corporate-AD-tree disclosure → Medium
  • Internet-exposed + named-server hostname (SPWEB01.corp.example) + corporate-AD-tree → Low-Medium
  • Intranet-only + any disclosure → Informational
  • Combine with hunt-auth-bypass Legacy-Protocol Matrix findings on the same host → upgrade the auth-bypass finding's severity since the attacker has UPN/SAM format ready
  1. Check the timestamp. If AV[7] returns a current FILETIME within ~5s of Date: header, the system clock is synced — useful intel for Kerberos golden-ticket forging (out of bug-bounty scope but red-team relevant).
  1. Cross-reference with subdomain enum. The DNS Tree name often reveals the parent forest — e.g. customer.parent-corp.example reveals the customer is a sub-domain INSIDE corporate-parent AD, not a separate tenant. This is a privacy / topology-disclosure escalation that programs sometimes accept as Medium.

Payload & Detection Patterns

Generic NTLM Type-1 anonymous probe (curl + raw socket fallback):

# Most one-shot curl runs DON'T return Type-2 because the connection closes.
# Use this as a quick probe to confirm NTLM is offered:
curl -sk -I -H "Authorization: NTLM TlRMTVNTUAABAAAAB4IIogAAAAAAAAAAAAAAAAAAAAAGAbEdAAAADw==" \
  "https://target.example/_api/web/CurrentUser" 2>&1 | grep -i "WWW-Authenticate"

Burp sendhttp1request (recommended for full Type-2 capture):

GET /_api/web/CurrentUser HTTP/1.1
Host: target.example
Authorization: NTLM TlRMTVNTUAABAAAAB4IIogAAAAAAAAAAAAAAAAAAAAAGAbEdAAAADw==
Connection: keep-alive
User-Agent: Mozilla/5.0

Python raw socket + AVPAIR decoder:**

import socket, ssl, base64, struct, re
from datetime import datetime, timezone

HOST = "target.example"
ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE

s = ctx.wrap_socket(socket.create_connection((HOST, 443)), server_hostname=HOST)
s.sendall(
    f"GET /_api/web/CurrentUser HTTP/1.1\r\n"
    f"Host: {HOST}\r\n"
    "Authorization: NTLM TlRMTVNTUAABAAAAB4IIogAAAAAAAAAAAAAAAAAAAAAGAbEdAAAADw==\r\n"
    "User-Agent: Mozilla/5.0\r\nConnection: keep-alive\r\n\r\n".encode()
)
data = b""
while True:
    chunk = s.recv(8192)
    if not chunk: break
    data += chunk
    if b"\r\n\r\n" in data: break

m = re.search(rb"WWW-Authenticate:\s*NTLM\s+([A-Za-z0-9+/=]{20,})", data, re.I)
if m:
    b = base64.b64decode(m.group(1).decode("ascii"))
    assert b[:8] == b"NTLMSSP\x00"
    tn_len, _, tn_off = struct.unpack_from('<HHI', b, 12)
    ti_len, _, ti_off = struct.unpack_from('<HHI', b, 40)
    print(f"TargetName: {b[tn_off:tn_off+tn_len].decode('utf-16-le', errors='ignore')!r}")
    av_types = {1:'NetBIOS Computer Name', 2:'NetBIOS Domain Name',
                3:'DNS Computer Name', 4:'DNS Domain Name',
                5:'DNS Tree Name', 7:'Times

Burp Collaborator NOT needed for this finding class — the data leak is in the synchronous response, not via OOB.

Common Root Causes

  1. Dual-auth IIS bindings on the public zone. Administrators leave NTLM enabled on the public-facing IIS site even when Forms auth is the intended entry point. Internal users get SSO; external attackers get the AD topology leak.
  1. Default IIS Application Pool identity left as ApplicationPoolIdentity. Combined with default hostname, signals provisioning never went past first-boot.
  1. Server never renamed from Windows-installer-generated hostname. Microsoft's default WIN-XXXXXXXXXXX 11-character pattern is the immediate tell. Sometimes also WORKGROUP\WIN-... in older boxes.
  1. Sub-domain joined to corporate forest without zone-isolation. European-integrator case: a a European importer's SharePoint test environment is a child domain inside a corporate global AD, disclosed via NTLM DNS Tree Name. The customer probably intends customer.parent-corp.example to be operationally separate but the NTLM Type-2 reveals the forest membership to anyone who probes.
  1. IIS Extended Protection NOT enabled. When is None (the default), the NTLM challenge is sent to any anonymous client. When set to Required, NTLM is restricted to authenticated callers — and the AV-pair leak is mitigated.
  1. No WindowsAuthentication removed from applicationHost.config for internet-exposed sites. SharePoint Central Admin sometimes leaves this enabled even when SP zone configuration only enables Forms.

Bypass Techniques

This skill describes a disclosure leak, not an authentication bypass. The "bypass" question is: how do defenders block this AV-pair leak while still allowing legitimate NTLM auth?

For the attacker: there's no "bypass" needed — the leak is the finding.

Gate 0 Validation

Before writing the report, confirm:

  1. What can the attacker do RIGHT NOW with this disclosure?
  • Internet-exposed + default hostname + corporate forest disclosed → Medium: attacker has UPN format for hunt-auth-bypass matrix probes, plus knows server has likely-default service accounts.
  • Intranet-only or only NetBIOS name → Informational.
  1. Does the program accept information-disclosure findings without a chained impact?
  • Many programs (Microsoft, large enterprise VDPs) DO accept this when the leaked info includes internal AD topology.
  • Many programs (Shopify, GitHub) reject info disclosure without a chained impact.
  • Read the program scope before submitting; if borderline, chain with a Tier-A finding from hunt-auth-bypass.
  1. Can you reproduce in <5 minutes from a fresh shell?
  • The Python snippet above is the canonical reproduction. Include it verbatim in the report.

Real Impact Examples

Scenario A — Enterprise SharePoint inside parent corporate AD

Target: https://target-portal.example/ — a enterprise dealer portal (test mirror) operated by a system integrator.

Sending the anonymous Type-1 message to /api/web/CurrentUser returned a Type-2 challenge whose AVPAIRS decoded to:

NetBIOS Domain Name:    <CustomerName>
NetBIOS Computer Name:  WIN-XXXXXXXXXXX
DNS Domain Name:        customer.parent-corp.example
DNS Computer Name:      WIN-XXXXXXXXXXX.customer.parent-corp.example
DNS Tree Name:          customer.parent-corp.example
Timestamp:              2026-05-13T15:55:37.922Z

Three escalation paths:

  1. Default Windows-installer hostname (WIN-XXXXXXXXXXX) — server was never renamed after OS install; strong signal of lazy provisioning. Likely default service-account passwords on the SQL backend, default WSUS config, etc.
  2. Sub-domain inside corporate-parent AD (customer.parent-corp.example) — the customer is a child domain inside 's global Active Directory. A compromise of this test farm has potential cross-trust to corporate-parent.
  3. UPN format known — combined with hunt-auth-bypass's discovery of an anonymous brute-force endpoint on /vtibin/Authentication.asmx, the attacker has both the credential format (firstname.lastname@customer.parent-corp.example or \firstname.lastname) and the unlimited submission endpoint.

  • Abugcrowd-reportingBugcrowd-specific reporting tactics complementing report-writing: VRT category search-and-fallback strategy when no exact match exists, manual severity override when VRT defaults underrate impact, severity-request paragraph as first body section, OOS-clause rebuttal templates (rate limiting on auth-flow endpoints, debug-info framing, user-enumeration with sensitive PII, theoretical-issue counter), chained-finding cross-reference patterns, target selection for QA-vs-prod programs, researcher-side hygiene (Bugcrowdninja email alias, account state restoration, friendly-tester posture). Use when filing a Bugcrowd submission, when VRT default seems wrong, when triager closes as OOS or downgrades severity, when chaining linked submissions, or when scope distinguishes production from QA. Pairs with report-writing and triage-validation.
  • Acloud-iam-deepCloud IAM red-team attack chain across AWS, Azure, GCP — focused on EXTERNAL exploitation paths and post-credential-discovery privilege analysis. Covers IAM enumeration (aws iam, az role, gcloud iam), STS/AssumeRole chaining, Azure Managed Identity abuse (via SSRF/leak), GCP service account JSON abuse, IMDSv1/v2 attacks via SSRF, K8s ServiceAccount token privilege analysis once held (token discovery / cluster exposure is owned by hunt-k8s), role-trust-policy confused-deputy, cross-account assume-role enumeration, IAM privilege escalation patterns (24+ AWS, 8+ Azure, 6+ GCP), and AWS Cognito Identity Pool unauthenticated-role attack chain (GetId → GetCredentialsForIdentity → IAM role abuse). Built for the case where recon yields a credential (key, JSON, token) and you need to know what it grants and how to escalate. Use when an AWS key / Azure secret / GCP service account JSON / K8s SA token surfaces from a code repo, JS bundle, APK, breach corpus, or SSRF chain.

Use BEFORE any PoC screenshot, BEFORE attaching a HAR, or whenever preparing evidence with session cookies or other-user PII. Pairs with bugcrowd-reporting and report-writing.
  • Ahunt-api-misconfigHunt API security misconfiguration — mass assignment, prototype pollution, HTTP verb tampering. Mass assignment: send {is_admin:true, role:admin, verified:true} on profile/account/reset endpoints — server blindly applies. JWT signature/crypto forging (alg:none, key confusion, kid/jku) is owned by hunt-jwt-crypto; this skill covers only non-crypto JWT handling. Prototype pollution: __proto__ injection in JSON merge / Object.assign / lodash _.merge → polluted prototype reaches sink (RCE in Node, XSS in browser). HTTP verb: GET-bypass-CSRF, X-HTTP-Method-Override, TRACE enabled. Detection: API responses with extra fields, JWTs in headers (decode at jwt.io). CORS misconfiguration (reflect-any-origin, null origin, subdomain-regex bypass, postMessage) is owned by hunt-cors. Use when hunting API misconfigs, mass-assignment, prototype pollution (JWT crypto → hunt-jwt-crypto).
  • Ahunt-aspnetHunt ASP.NET-specific surface — ViewState deserialization (signed-only vs encrypted), machineKey recovery, dual-parser MAC-bypass anti-pattern, request-validator bypass, trace.axd/elmah.axd disclosure, load-balanced ViewState cross-node failures, SafeControl enumeration via reflection, customErrors mode=Off stack-trace leaks, classic Webforms .aspx/.asmx/.svc surface. Built for ASP.NET Webforms + WCF + SharePoint farms.
  • Ahunt-atoHunt account takeover taxonomy — 9 distinct paths to ATO, plus chains. Paths: (1) password reset flaws (host-header injection redirects token, predictable/numeric token, Referer leak, no-expiry/reuse), (2) email change without re-auth, (3) OAuth account-link CSRF, (4) MFA bypass (per hunt-mfa-bypass), (5) session fixation, (6) JWT manipulation (forge token to another identity; crypto details → hunt-jwt-crypto), (7) password change without step-up (chain with login timing/length oracle), (8) social-recovery / security-question brute-force, (9) SSO subdomain takeover at OAuth redirect_uri. Chains: cookie theft + password oracle + no step-up = persistent ATO; lax redirect_uri = auth-code theft; dangling-CNAME takeover at redirect_uri = ATO. Validate: demonstrate real takeover of test account B from attacker A's session; OOB/Collaborator confirm blind token-leak steps. Use when hunting ATO chains, testing password reset / email change / MFA / OAuth / session / JWT, or chaining primitives toward Critical.
  • Ahunt-auth-bypassHunting skill for auth bypass vulnerabilities. Built from 12 public bug bounty reports across SAML XSW / parser-differential (GitHub Enterprise CVE-2025-25291/25292), SAML signature stripping (Uber, Rocket.Chat, samlify CVE-2025-47949), SAML domain enforcement bypass via control characters (HackerOne 2024), partner-portal cross-IdP assertion reuse (Slack), WordPress XMLRPC bypassing SSO (Uber), JWT alg-confusion HS256/RS256 (Jitsi), JWT signature-validation skip (Linktree, Newspack), and token-audience confusion (Argo CD CVE-2023-22482). For standalone JWT signature/crypto forging (alg:none, key confusion, kid/jku) see hunt-jwt-crypto; this skill covers JWT only inside SSO/SAML/token-trust bypass chains. SAML assertion-layer attacks (XSW, comment injection, signature stripping, XXE-in-assertion) are owned by hunt-saml; this skill owns the broader cross-protocol auth-bypass taxonomy.
