A comprehensive guide and toolkit for analyzing malware Command-and-Control (C2) communication. This method helps security analysts reverse engineer network traffic captured from malware samples, identifying beaconing patterns, decoding custom protocols (HTTP, DNS, etc.), and mapping C2 infrastructure for advanced threat detection and threat intelligence gathering.

A comprehensive guide and workflow for digital forensics investigators to analyze raw email headers. This tool helps trace the true origin of suspicious emails, verify sender authenticity, and detect advanced spoofing techniques by validating crucial protocols like SPF, DKIM, and DMARC. It covers everything from header parsing to domain infrastructure analysis and IP reputation checks.

A comprehensive guide for deep packet inspection and network forensics using Wireshark and tshark. This skill is critical for incident response, where it allows users to capture, filter, and analyze network packet data to identify malicious command-and-control traffic, diagnose complex protocol issues, extract indicators of compromise (IOCs), and reconstruct data exfiltration paths. Use it for validating security rules and understanding network anomalies.

This comprehensive guide details how to deploy and configure a resilient Command and Control (C2) infrastructure using the advanced Sliver framework. It covers setting up multi-protocol listeners (HTTPS, mTLS, DNS, WireGuard), implementing complex redirectors, domain fronting, and establishing operational security controls for professional red team engagements and advanced security assessments.

This skill details the advanced technique of DCSync, which exploits the Microsoft Directory Replication Service Remote Protocol (MS-DRSR) to impersonate a Domain Controller. It is primarily used in authorized red-teaming and penetration testing to dump sensitive credentials, extract the KRBTGT hash, and ultimately forge Golden Tickets, establishing deep domain persistence. Ideal for security auditors and offensive security professionals.

A comprehensive guide for conducting authorized wireless network penetration tests. This skill assesses the overall security posture of WiFi infrastructure, covering weak encryption protocols, captive portal bypasses, Evil Twin attacks, WPA2/WPA3 handshake capture, and rogue access point detection. It evaluates wireless authentication methods, network segmentation, and the effectiveness of WIDS/WIPS systems.

A comprehensive guide to deploying and configuring Suricata, a high-performance IDS/IPS. This skill covers setting up multi-threaded packet capture, integrating Emerging Threats rulesets, generating structured EVE JSON logs, and enabling deep protocol inspection (HTTP, TLS, DNS). It enables real-time threat detection and seamless SIEM integration for centralized security monitoring.

TLS 1.3 is the latest Transport Layer Security protocol, offering significant security and performance improvements over TLS 1.2. This guide details how to configure and validate TLS 1.3 on various environments, including Nginx, Apache, and Python applications. It covers advanced topics such as Perfect Forward Secrecy (PFS), HSTS implementation, modern cipher suites, and best practices for securing modern web services.

This skill provides methods and tools for detecting sophisticated cyber attacks targeting Supervisory Control and Data Acquisition (SCADA) and Industrial Control Systems (ICS). It focuses on detecting anomalies like unauthorized command injection, Man-in-the-Middle attacks on industrial protocols (Modbus, DNP3), and data manipulation, which traditional IT security tools often miss. Usage involves establishing deterministic communication baselines and monitoring network traffic for deviations.

A specialized tool for detecting anomalies within DNP3 (Distributed Network Protocol 3) communications used in critical SCADA and energy sector infrastructure. It employs deep packet inspection and baseline comparison to monitor for unauthorized control commands, protocol violations, suspicious firmware update attempts, and deviations from established operational traffic patterns.

This skill provides comprehensive anomaly detection for Modbus/TCP and Modbus RTU traffic in Operational Technology (OT) and Industrial Control Systems (ICS). It monitors function codes, validates register access, analyzes timing, and detects unauthorized clients. By utilizing advanced tools like Zeek, Suricata, and custom Python models, it helps establish behavioral baselines and identify potential cyber threats.

This comprehensive guide outlines methods to identify and exploit specific IPv6 vulnerabilities, including SLAAC spoofing, Router Advertisement (RA) manipulation, and Neighbor Discovery Protocol (NDP) attacks. It is designed strictly for authorized penetration testing to assess dual-stack security controls, detect unauthorized tunnels (like Teredo or 6to4), and validate network defenses against IPv6-specific threats. Always obtain explicit written authorization before use.
