This guide details the methodology for conducting internal network penetration tests, simulating an attacker operating from an assumed breach state. It covers initial network reconnaissance, Active Directory enumeration, advanced credential harvesting techniques (e.g., Kerberoasting, Pass-the-Hash), and lateral movement exploitation to determine the full blast radius of a potential breach. Essential for comprehensive security auditing.

This skill provides a comprehensive guide to implementing microsegmentation policies. It details how to move beyond traditional network boundaries (VLANs) to enforce least-privilege access control between individual workloads using identity and application context. Essential for preventing lateral movement and establishing a robust zero-trust architecture aligned with industry compliance standards.

This guide details the robust process of implementing VLAN-based (802.1Q) network segmentation on managed switches. It is crucial for isolating critical zones—such as DMZ, servers, and IoT—to meet strict compliance standards (PCI-DSS, HIPAA) and significantly limiting the blast radius during a security incident by controlling lateral movement. Includes port hardening and ACL configuration.

This comprehensive guide provides a structured, multi-stage workflow for containing active security breaches. It details both short-term and long-term strategies, including network segmentation, endpoint isolation, credential revocation, and evidence preservation. Use this process during confirmed intrusions, ransomware attacks, or lateral movement events to effectively stop adversary activity and secure critical assets before eradication.

A specialized Python detector designed to monitor Operational Technology (OT) historian servers (such as OSIsoft PI, Ignition, etc.). It identifies critical indicators of compromise (IOCs), including unauthorized network connections, data manipulation attempts, and lateral movement activities that bridge IT and OT zones. Use this skill when validating data integrity and investigating potential cyber breaches in industrial environments.

Execute deep, stealthy red team exercises that emulate real-world sophisticated adversaries. This process maps attacks to the MITRE ATT&CK framework, testing an organization's entire security posture—including detection, incident response, and containment capabilities (Blue Team). It is designed for simulating full attack lifecycles (initial access, lateral movement, exfiltration) to validate security investments and meet regulatory requirements (TIBER-EU, CBEST). Requires executive authorization and defined Rules of Engagement.

Kerberoasting is a credential access attack (T1558.003) targeting Active Directory service accounts with Service Principal Names (SPNs). This skill demonstrates using Impacket to request Kerberos TGS tickets for these accounts. The resulting RC4 or AES-encrypted tickets are then cracked offline using tools like Hashcat or John the Ripper, allowing attackers to recover service account credentials for lateral movement during authorized penetration testing or red-team engagements.

A comprehensive guide for authorized penetration testing, demonstrating how to identify and exploit critical vulnerabilities in the SMB protocol (e.g., EternalBlue, PrintNightmare). This skill covers network enumeration, lateral movement techniques (Pass-the-Hash, SMB Relay), and post-exploitation activities using Metasploit and Impacket tools to assess enterprise network security posture.

This utility performs comprehensive forensic analysis on memory dumps. It leverages industry-standard tools like Volatility and Mimikatz to extract sensitive information, including cached credentials, NTLM/LM hashes, Kerberos tickets, and authentication tokens. It is crucial for incident response, assessing the scope of credential compromise, and investigating lateral movement attacks.

This tool analyzes Windows Event Logs (ID 4688, Sysmon ID 1) and WMI-Activity Operational events to detect suspicious lateral movement. It specifically hunts for WmiPrvSE.exe spawning child processes (like cmd.exe or powershell.exe) or identifying WMI event subscriptions, which are common indicators of remote code execution and persistence.

This guide details the deployment of deception technologies, including canary files and honeypot shares, to detect ransomware activity at its earliest stages. It outlines configuring file integrity monitoring (FIM) and using specialized tokens to trigger alerts when ransomware attempts encryption or performs lateral movement, significantly enhancing security posture beyond standard EDR.

A comprehensive guide for deploying and managing network deception systems using industry-leading honeypot platforms like OpenCanary, T-Pot, and Cowrie. This skill helps security professionals detect unauthorized access attempts, trace lateral movement, and gather critical threat intelligence by simulating vulnerable services within a controlled environment. Ideal for enhancing network security architecture and creating early warning indicators for intrusions.
