Free Udemy Course 2025: Advanced Wireshark for Threat Hunting and Network Forensics

This is the definitive, advanced-level training designed for seasoned security analysts, incident responders, and aspiring threat hunters. Forget "Wireshark 101." This course transforms your packet analysis skills from passive observation into proactive, surgical threat hunting and forensically sound evidence collection.You will learn to think in packets, treating every network capture as a digital crime scene. We pivot immediately from basic navigation to advanced methodologies - starting with configuring custom environments using TShark and TCPDump for remote, covert, and automated acquisition in the field.The core of this course focuses on identifying the invisible. You will master advanced filtering techniques (display and capture filters) that allow you to collapse millions of packets into the ten that contain an Indicator of Compromise (IOC). We dive deep into protocol anatomy, teaching you to spot layer evasion, protocol anomalies, and the subtle behaviors of modern malware - including DNS tunneling, DGA (Domain Generation Algorithms), and the rhythmic, low-and-slow patterns of a Command and Control (C2) beacon.Crucially, this training goes beyond detection. You will learn the forensic workflow required to follow suspicious conversations, reconstruct attacker activity (including credential theft), and safely extract malicious payloads directly from the capture file for sandboxing and analysis. We leverage Wireshark's powerful statistics and IO graphs to identify "unknown unknowns," turning massive data sets into visual proof of anomalies and attacks like smash-and-grab data exfiltration.By the end of this course, you won't just analyze traffic; you will hunt threats, gather irrefutable evidence, and master the techniques necessary to defeat sophisticated network attackers. This is your ticket to becoming the expert who finds the bad packet in any network investigation.
