Wireshark Study Notes

This educational guide on Wireshark from the MasterMinds Group provides a comprehensive tutorial for beginners and professionals on using Wireshark for packet sniffing, traffic analysis, and network forensics. It offers practical applications, filter techniques, packet inspection, decryption strategies, and forensic investigation scenarios.

Wireshark is presented not just as a packet sniffer but as an essential cybersecurity and networking tool. It allows deep packet inspection, real-time traffic analysis, and post-event forensic review.

With its intuitive GUI and powerful filtering features, users can dissect traffic across all OSI layers. Practical applications are shown for spotting unauthorized activity, filtering by protocol or behavior, and decrypting encrypted traffic with captured session keys. Advanced examples include analyzing DNS tunneling, SMB decryption, FTP abuse, and more. Script-based decryption using NTLM credentials and HMAC is also demonstrated for in-depth security research. Wireshark supports firewall rule generation and credential extraction to streamline security workflows.
