Analyzing Network Traffic With Wireshark
Capture and interpret PCAP-style network traffic with Wireshark workflows to debug incidents, verify TLS behavior, and hunt malicious patterns.
Overview
analyzing-network-traffic-with-wireshark is an agent skill most often used in Ship (also Operate) that guides Wireshark-based network traffic analysis for security and debugging.

What problem does it solve?
You see flaky connectivity or a possible breach indicator but only have logs—not a clear picture of which hosts, ports, and payloads are involved.
Who is it for?
Solo builders doing self-serve packet review during staging issues, pen-test prep, or post-deploy anomaly checks.
Skip if: Regulated environments requiring chain-of-custody forensics by certified analysts without human verification of captures.
When should I use this skill?
User needs Wireshark or network packet capture analysis for security investigation, protocol debugging, or traffic validation.
What do I get? / Deliverables
You get agent-guided capture analysis steps, filter hypotheses, and protocol-level findings you can attach to a security review or incident ticket.
- Filter and display hypotheses for relevant flows
- Security-oriented traffic finding summary for review or incident notes
Recommended Skills
Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
Wireshark analysis is canonical pre-ship security validation and post-incident review; shelf it under Ship security as the first formal hardening checkpoint. Packet-level inspection supports threat validation, misconfiguration detection, and evidence for security reviews before and after release.
Where it fits
Validate staging captures before launch to confirm no unexpected outbound calls or cleartext credentials.
Compare failing client sessions to a known-good PCAP to isolate DNS, TLS, or timeout issues.
Document recurring beacon-like flows discovered during anomaly review for a lightweight runbook.
How it compares
Use for guided PCAP interpretation in the agent—not as a substitute for enterprise NDR appliances or automated SOC playbooks.
Common Questions / FAQ
Who is analyzing-network-traffic-with-wireshark for?
Developers and indie operators who use Claude or similar agents to walk through Wireshark captures during security reviews or outages.
When should I use analyzing-network-traffic-with-wireshark?
In Ship security when validating TLS and API exposure before launch; in Operate errors/monitoring when triaging suspicious traffic or protocol mismatches after deploy.
Is analyzing-network-traffic-with-wireshark safe to install?
Treat PCAPs as sensitive data; review the Security Audits panel on this Prism page and avoid uploading production secrets into untrusted agent sessions.
