A comprehensive guide covering advanced Kerberos attacks against Active Directory environments. Techniques include AS-REP roasting, Kerberoasting, forging golden, silver, diamond, and sapphire tickets, and exploiting delegation abuse. Designed for penetration testers and red teams to simulate sophisticated domain compromise scenarios.

This skill guides the architecture and implementation of SAML 2.0 identity federation between on-premises Active Directory and Microsoft Entra ID (Azure AD). It covers establishing seamless Single Sign-On (SSO) capabilities, eliminating the need for separate credentials and ensuring secure, cross-domain authentication for cloud applications.

This technique exploits the Active Directory attribute `msDS-KeyCredentialLink` by injecting attacker-controlled public keys (Shadow Credentials). Using tools like pyWhisker and Certipy, the attacker forces the target account to register a new key. Subsequently, by leveraging PKINIT (Public Key Cryptography for Initial Authentication in Kerberos), the attacker can obtain a service ticket and recover the target's NT hash, achieving a stealthy, password-less, complete account takeover.

A powerful offensive security toolkit for red-teaming and penetration testing. It systematically enumerates and exploits various misconfigurations within Active Directory Certificate Services (AD CS) using Certipy. This allows attackers to forge privileged certificates, perform PKINIT authentication, and achieve domain compromise and privilege escalation, even without knowing user passwords. Ideal for validating security hardening.

This skill enables comprehensive security graph mapping by ingesting both on-premises Active Directory data (via SharpHound) and cloud Entra ID data (via AzureHound) into BloodHound CE. It analyzes complex, hybrid attack paths, allowing security teams to identify critical privilege escalation chains from low-privileged accounts to Tier-0 assets, mapping findings to MITRE ATT&CK.

NetExec is a powerful, protocol-oriented tool for penetration testing, designed for assessing and exploiting Windows and Active Directory environments. It facilitates lateral movement by authenticating over protocols like SMB, WinRM, LDAP, and MSSQL. Key functions include password spraying, comprehensive network enumeration, command execution, and dumping critical credentials (SAM, LSA, NTDS) during post-exploitation phases.

This skill details the advanced red-teaming technique of exploiting Active Directory Certificate Services (AD CS) via the ESC8 path. By abusing the HTTP web-enrollment endpoint and relaying coerced NTLM credentials, an attacker can compel a domain controller to request a machine certificate. This certificate is then used to compromise the domain via PKINIT and DCSync.
