From 77412901933386ca2d2e42da1ec96bedf9e53911 Mon Sep 17 00:00:00 2001 From: CyberSecurityUP Date: Fri, 2 Oct 2026 20:13:19 -0300 Subject: [PATCH] =?UTF-8?q?feat(agents):=20deep=20Active=20Directory=20sui?= =?UTF-8?q?te=20=E2=80=94=2025=20host/infra=20skills=20+=207=20AD=20chains?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
