Test it
Using "wireshark-network-traffic-analysis". A user asks how to investigate slow access to an internal web application.
Expected outcome:
- Check conversations and service response time for the web server.
- Filter for retransmissions, duplicate acknowledgements, resets, and zero-window events.
- Compare I/O graph spikes with user-reported time ranges.
Using "wireshark-network-traffic-analysis". A user asks how to triage a suspicious PCAP from an endpoint alert.
Expected outcome:
- Start with protocol hierarchy, endpoints, DNS queries, and conversation summaries.
- Look for regular beaconing, random-looking domains, unusual ports, and large outbound transfers.
- Document any indicators with packet numbers, timestamps, and related streams.
Using "wireshark-network-traffic-analysis". A user asks how to review plaintext credential exposure.
Expected outcome:
- Limit analysis to authorized captures and approved systems.
- Review HTTP form submissions and stream contents for exposed usernames, passwords, or tokens.
- Redact sensitive values before sharing findings or reports.
Security Audit
High Riskv5 • 7/7/2026 Open versioned report
Most static findings are false positives caused by Markdown code fences and Wireshark filter examples. One high-confidence issue remains: the TLS troubleshooting section directs users to obtain a server private key, which requires stronger handling guidance.

Crypto seed/private key mention
- Obtain server private key
The skill tells users to obtain a server private key for TLS decryption. That can be legitimate with authorization, but it involves sensitive secret material that could compromise TLS if mishandled.

What You Can Build
Diagnose Network Outages
Review packet loss, retransmissions, connection resets, and traffic timing to isolate service or path problems.
Investigate Suspicious Traffic
Filter PCAP files for unusual DNS, port scanning, beaconing, plaintext credentials, and unexpected external connections.
Document Incident Evidence
Use streams, statistics, endpoints, and exported dissections to create clear evidence for incident timelines.
Try These Prompts
Start a Basic PCAP Review
Help me review this PCAP in Wireshark. List the first filters and statistics I should check for basic triage.
Troubleshoot Web Slowness
Guide me through Wireshark analysis for a slow web application. Focus on retransmissions, response times, resets, and traffic volume.
Investigate Possible Malware Traffic
Help me analyze suspected malware traffic in Wireshark. Prioritize DNS patterns, beaconing intervals, unusual ports, and endpoint summaries.
Build an Incident Evidence Workflow
Create a Wireshark workflow for preserving evidence from an authorized capture. Include filters, streams, exported views, and validation checks.
Best Practices
- Capture only traffic you are authorized to inspect.
- Use capture filters to reduce sensitive data collection.
- Store PCAP files securely and redact secrets before sharing results.
Avoid
- Do not capture third-party traffic without approval.
- Do not paste credentials, tokens, private keys, or raw PCAP secrets into AI tools.
- Do not treat a single packet pattern as proof without corroborating context.
Frequently Asked Questions
Does this skill run Wireshark automatically?
No. It provides analysis workflows, filters, and review steps for users operating Wireshark.
Can it analyze encrypted traffic?
It can guide metadata review. Payload decryption requires authorized keys, key logs, or supported protocol settings.
Is live packet capture covered?
Yes. The skill explains live capture setup, interface selection, filters, and operational limits.
Can it help with incident response?
Yes. It supports PCAP triage, stream review, suspicious traffic detection, and evidence documentation.
What data should users avoid sharing?
Users should avoid sharing credentials, tokens, private keys, personal data, and unsanitized packet captures.
Who is this skill for?
It is for network engineers, security analysts, incident responders, and learners with authorization to inspect traffic.
