Wireshark is a free, open-source network protocol analyzer used in ethical hacking to:
- Capture and inspect live traffic (e.g., HTTP, VoIP, DNS).
- Detect vulnerabilities like unencrypted passwords or misconfigured protocols.
- Network Analysis (e.g., ARP spoofing, DDoS) by examining packet behavior.
- Troubleshoot networks by identifying latency, dropped packets, or misrouted data.
This Wireshark hands-on course covers sniffing sensitive data, decrypting SSL/TLS, and mapping network traffic to identify weak points. Please note that ethical hackers must always obtain permission before using Wireshark.
