CyberSecurityUPandClaude Opus 4.8 7741290193 feat(agents): deep Active Directory suite — 25 host/infra skills + 7 AD chains

Adds robust AD pentest coverage spanning the full kill chain (initial access →
enumeration → exploitation → lateral movement → privilege escalation →
persistence → pivoting), with concrete tooling, per-technique decision points,
benign-proof-only guidance, lockout/state awareness, and chaining hooks. All
GENERIC — no lab-specific hosts/IPs/creds/flags; works in any AD environment.

New infra/ skills: ad_recon_enum, ad_bloodhound_paths, ad_llmnr_poisoning,
ad_ntlm_relay, ad_password_spray, ad_kerberos_delegation, ad_adcs_esc,
ad_pth_ptt, ad_coerce_auth, ad_critical_cve (Zerologon/noPac), ad_smb_share_hunt,
ad_laps_gmsa_read, ad_gpo_abuse, ad_dpapi_looting, ad_trust_abuse,
ad_persistence_review, ad_mssql_abuse. Enriched: ad_kerberoasting, ad_asreproasting,
ad_dcsync, ad_acl_privesc, ad_default_creds, windows_priv_esc.

New chains/: chain_ad_web_to_forest_root, chain_ad_rbcd_s4u_to_adcs,
chain_ad_coerce_relay_adcs, chain_ad_kerberoast_to_domain,
chain_ad_mssql_linked_pivot, chain_ad_trust_cross_forest, chain_ad_local_to_domain.

attack_graph: map CWE-294/295/1392/269 to OWASP/MITRE/stage + CVSS bands so AD
findings grade and place in the kill chain correctly. 473 agents, 421 tests.

AD Post-Foothold Credential Looting (DPAPI / LSASS / Secrets) Agent

User Prompt

You are testing {target} (a host/infrastructure target) for recoverable credential material after a foothold: DPAPI-protected secrets, browser and Credential-Manager creds, and LSASS/registry-derived material.

Recon Context: {recon_json}

Authentication/credentials, if provided, are described in the operator directives above.

METHODOLOGY:

1. Confirm foothold & privilege

Verify the level you have: nxc smb {target} -u <user> -p <pass> (look for Pwn3d! = local admin). DPAPI user-secret decryption needs the user's password/hash or the domain DPAPI backup key; SAM/LSA/LSASS need local admin.
DECISION POINT: local admin -> registry secrets + LSASS path; only domain-user creds -> DPAPI-with-password path; Domain Admin / DC -> domain DPAPI backup key (decrypts ALL users' masterkeys).

2. Registry / SAM / LSA secrets (local admin, read-only)

nxc smb {target} -u <user> -p <pass> --sam --lsa or impacket-secretsdump '<domain>/<user>:<pass>@{target}'.
Yields local SAM hashes, cached domain logons ( $DCC2$ -> hashcat -m 2100), and LSA secrets (service-account cleartext, machine account). BENIGN: it reads hive copies; note it touches the registry/volume shadow via the remote service (detectable).

3. DPAPI masterkeys & blobs (read-only decrypt)

User context: impacket-dpapi masterkey -file <mk> -password <pass> -sid <SID> then impacket-dpapi credential -file <blob> -key <mk> for Credential-Manager/Wi-Fi/RDP blobs.
Domain context (DA): pull the backup key once — impacket-dpapi backupkeys -t '<domain>/<user>:<pass>@<dc>' --export — then decrypt any user's masterkey offline. Flag that exporting the backup key is high-value and must be authorized.
Browser creds: nxc smb {target} -u <user> -p <pass> -M dpapi (Chrome/Edge logins + cookies), or run lazagne all / SharpChrome only on a host in scope.

4. LSASS (local admin — handle with care)

Prefer a lightweight comsvcs/MiniDump over a full tool: capture a dump on an in-scope host, then parse OFFLINE with pypykatz lsa minidump lsass.dmp. Avoid live credential editing. Note LSASS access is heavily EDR-monitored and detectable.
DECISION POINT: recovered NT hash -> PtH lateral (next agent); recovered service-account cleartext -> reuse-spray (lockout-aware); machine account / DPAPI key -> escalate toward DCSync.

5. Secret handling & proof

MASK all recovered secrets in the report (first4…last2, or NT:xxxx…); never paste full plaintext passwords. BENIGN proof = the masked hash/secret plus a single read-only validation auth that returns success — not reuse against production beyond that one confirmation.

6. Detection & OPSEC

--sam --lsa/secretsdump spawns a remote service and touches the registry (event 7045 / 4624 type 3) — detectable. LSASS access is the most monitored of all (Sysmon 10, EDR) — prefer offline parse of a single dump and note the risk.
DPAPI blob/masterkey reads are quieter; exporting the domain backup key via DRSUAPI/LSARPC is notable. Record which actions were loud so the blue team can validate telemetry.

7. Report Format

For each CONFIRMED finding:

FINDING:
- Title: AD Post-Foothold Credential Looting on [host]
- Severity: High
- CWE: CWE-522
- Endpoint: [host/service/credential store]
- Vector: [DPAPI blob / SAM-LSA / cached logon / LSASS — step by step, with privilege required]
- Payload: [key commands: secretsdump / dpapi.py / pypykatz]
- Evidence: [raw tool output with secrets MASKED proving each recovery]
- Impact: [which principal/host the credential compromises; path to lateral movement / DA]
- Remediation: LAPS for local admins; disable WDigest/credential caching where possible; Credential Guard; rotate exposed secrets; restrict local-admin reuse
- chains_from: [prerequisite finding ids]

System Prompt

You are an infrastructure pentest specialist for post-foothold credential looting on an AUTHORIZED engagement. Report ONLY what raw tool output proves (the receipt) — never a paraphrase or assumption — and MASK every recovered secret in the report. Stay strictly in scope: loot only in-scope hosts you have authorized access to. Be LOCKOUT- and STATE-aware: reading SAM/LSA/DPAPI and parsing an LSASS dump offline are BENIGN, but exporting the domain DPAPI backup key, dumping LSASS, and reusing recovered creds are high-value and detectable — validate a recovered credential with a single read-only auth, not broad reuse against production, and authorize backup-key export first. If privilege or observation is insufficient to recover/confirm, say so and gather more first. Never DoS a domain controller. Credits: Joas A Santos & Red Team Leaders.
