ad-ntlm-relay

NTLM relay deep-dive — `ntlmrelayx` configuration matrix (SMB, LDAP, LDAPS, HTTP, RPC, IMAP, MSSQL), SMB-signing bypass, target selection (DC for DCSync, ADCS for cert, LAPS reader for cleartext), session relay vs cracking trade-off, multi-relay (forward auth from one victim to many).

Content

87%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A tight, highly actionable operational reference that uses matrices and real ntlmrelayx/hashcat commands to convey a lot with few tokens. The main gap is the absence of explicit validation/verification steps in the destructive relay chains.

Suggestions

Add an explicit verification checkpoint after each destructive chain, e.g. check that msDS-AllowedToActOnBehalfOfOtherIdentity was set before running getST, or confirm the KeyCredentialLink was written before certipy auth.

For the multi-relay and MSSQL xp_cmdshell examples, note how to confirm a relay succeeded (expected ntlmrelayx output lines) so the operator can detect failure mid-chain.

DimensionReasoningScore

Conciseness

Lean and efficient — tables for the target/signing matrices and copy-paste code blocks with no padding explaining what NTLM or relay is; every section adds operational value and assumes competence.

3 / 3

Actionability

Provides fully executable commands such as `impacket-ntlmrelayx -t ldap://dc.target.local --delegate-access --escalate-user 'lowpriv'`, `impacket-getST ...`, `crackmapexec smb ... --gen-relay-list`, and `hashcat -m 5600`, copy-paste ready with expected outcomes in comments.

3 / 3

Workflow Clarity

Chains are sequenced (coerce → relay → S4U2Proxy) with inline comments, but the destructive operations (RBCD, shadow creds, Domain Admin escalation) lack explicit verification checkpoints, capping workflow clarity at 2 per the destructive-ops guideline.

2 / 3

Progressive Disclosure

A focused, self-contained ~110-line reference organized into clear sections (target matrix, signing, chains, crack-vs-relay, mitigations, OPSEC, references) with one-level external references and no nested/2+-level-deep references; no bundle files exist to score against.

Description

82%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A specific, jargon-accurate description that names concrete relay targets and techniques with strong trigger terms and low conflict risk. Its main weakness is the absence of an explicit 'Use when...' trigger clause, which caps completeness.

Suggestions

Append an explicit trigger clause such as 'Use when the user needs to relay captured NTLM auth, configure ntlmrelayx, or choose relay targets vs cracking.'

Lead with the core action (e.g., 'Relays captured NTLM authentication to downstream targets...') before the sub-topic list so the 'what' reads as a verb phrase.

DimensionReasoningScore

Specificity

Lists multiple concrete capabilities — "ntlmrelayx configuration matrix (SMB, LDAP, LDAPS, HTTP, RPC, IMAP, MSSQL)", "SMB-signing bypass", "target selection (DC for DCSync, ADCS for cert, LAPS reader for cleartext)", "multi-relay" — rather than vague language.

3 / 3

Completeness

Clearly answers the "what" (a deep-dive covering the listed relay topics) but lacks an explicit "Use when..." trigger clause, so per the guidelines completeness is capped at 2.

2 / 3

Trigger Term Quality

Good coverage of the natural terms a practitioner would say — "ntlm relay", "ntlmrelayx", "smb signing", "ldap", "ldaps", "adcs", "mssql", "impacket", "multi-relay" — matching the rubric's good-coverage anchor.

3 / 3

Distinctiveness Conflict Risk

A clear niche — NTLM relaying via ntlmrelayx with SMB-signing and ADCS/LDAP specifics — with distinct triggers unlikely to fire for unrelated skills.
