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 skill analyzes Zeek conn.log and NetFlow data to proactively detect advanced indicators of ransomware activity. It identifies critical threats such as Command and Control (C2) beaconing patterns, connections to TOR exit nodes, large-scale data exfiltration flows, and suspicious DNS anomalies. It is essential for threat hunting and complex security incident response.

This guide details comprehensive detection methods for DCSync attacks (MITRE T1003.006) in Active Directory. Attackers abuse legitimate directory replication protocols to extract sensitive password hashes. Detection relies on auditing Windows Event ID 4662 for unauthorized access attempts to critical Directory Service GUIDs, specifically flagging non-domain-controller accounts attempting replication calls. Essential for threat hunting and incident response.

This guide details how to hunt for DCSync attacks (MITRE ATT&CK T1003.006) in Active Directory environments. It focuses on analyzing Windows Security Event ID 4662, specifically looking for DS-Replication-Get-Changes requests originating from non-domain-controller accounts. This technique is critical for incident response, purple teaming, and detecting unauthorized credential theft via Active Directory replication abuse.

Conduct hypothesis-driven threat hunting for Command-and-Control (C2) activity (T1071). This skill guides the analysis of SIEM/EDR network telemetry to detect anomalous outbound traffic, rare destination IPs, non-standard ports, and unusual connection frequencies, helping identify beaconing or data exfiltration attempts. Essential for proactive defense and incident response.

This skill provides a comprehensive guide to implementing robust USB device control policies. It restricts unauthorized removable media access to mitigate data exfiltration risks and prevent malware introduction via USB endpoints. Learn how to deploy granular policies using Group Policy Objects (GPO), Microsoft Intune, or advanced Endpoint Detection and Response (EDR) platforms to meet strict compliance standards.

This skill provides a comprehensive framework for simulating and testing disaster recovery plans against ransomware threats. It guides users through measuring Recovery Time Objective (RTO) and Recovery Point Objective (RPO), validating clean backup restores, and hardening security controls to ensure organizational resilience. It is designed for tabletop exercises and compliance auditing, not for active incident response.
