This guide details how to build and manage a robust two-tier Public Key Infrastructure (PKI) using OpenSSL. Learn to establish a Root CA and an Intermediate CA, issue server and client certificates, configure Certificate Revocation Lists (CRLs), and implement best practices for secure key management and certificate policy enforcement, ensuring compliance and high security standards.

This guide details the exploitation of the Active Directory Certificate Services (AD CS) ESC1 vulnerability. By leveraging misconfigurations, an attacker can request certificates impersonating high-privileged users (e.g., Domain Admins). The workflow covers AD enumeration, forging certificates with arbitrary Subject Alternative Names (SANs), authenticating via PKINIT, and ultimately escalating domain privileges using tools like mimikatz. Essential for authorized red team and penetration testing.

This tool simulates various BGP hijacking scenarios, including prefix hijacking and route leaks, within authorized, isolated lab environments. It is designed to assess the effectiveness of critical network defenses such as RPKI deployment, route origin validation, and BGP monitoring systems against unauthorized route announcements. It is a training and validation tool for network operations teams.

This guide details the process of implementing BGP route origin validation using Resource Public Key Infrastructure (RPKI). Learn how to create Route Origin Authorizations (ROAs), deploy RPKI validators, and configure Route Origin Validation (ROV) on major routers like Cisco IOS-XE and Juniper Junos. This technique is crucial for preventing malicious route hijacking and securing internet routing paths.

This guide details how to implement HashiCorp Vault's dynamic secrets engine. It automates the generation, lease management, and rotation of short-lived credentials for databases (e.g., PostgreSQL, MySQL), AWS IAM, and PKI certificates. This method eliminates the use of static, hardcoded secrets, enforcing zero-trust principles and meeting stringent compliance mandates like PCI-DSS.

Napkin gives Copilot CLI users a browser whiteboard to draw, sketch, and add sticky notes; Copilot reads snapshots and JSON data, then replies with analysis, suggestions, and next steps for business-oriented thinkers.

This expert playbook details advanced techniques for bypassing SSL pinning mechanisms (Certificate, Public Key, SPKI) on mobile applications running on Android and iOS. It provides practical methods using tools like Frida and Objection, covering various frameworks (Flutter, React Native, Xamarin) and multiple pinning types to enable the interception and analysis of encrypted HTTPS traffic.

Implements HashiCorp Vault's dynamic secrets engine to automatically generate, lease, and rotate short-lived credentials for databases (e.g., Postgres, MySQL), AWS IAM keys, and PKI certificates. This eliminates the risk associated with storing static secrets, ensuring compliance with zero-trust principles and automating the entire secret lifecycle.

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 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.
