What is the Wireshark Network Traffic Analysis skill?

It is a specialized Claude Code skill that provides expert guidance and standardized workflows for using Wireshark to capture, filter, and analyze network data.

How do I use this skill for troubleshooting slow applications?

The skill guides you through checking service response times, identifying TCP retransmissions, and using I/O graphs to pinpoint network congestion or packet loss.

Can this skill help detect cyber attacks?

Yes, it includes specific analysis patterns for detecting port scanning, ARP spoofing, suspicious DNS activity, and plaintext credential transmission.

Does this skill work with existing PCAP files?

Absolutely. It provides comprehensive display filters and statistical analysis techniques that can be applied to both live captures and offline PCAP/PCAPNG files.

What protocols are covered by this skill?

The skill covers a wide range of protocols including TCP, UDP, HTTP/HTTPS, DNS, FTP, SSH, ICMP, ARP, DHCP, and SMB.
