# Wireshark twoo twooo two twoo..

I opened the file in **Wireshark**. After analyzing all the packets and following the **TCP streams**, I noticed that there were too many fake flags in **TCP streams 6 and 11**.

Then I checked the IP addresses and found that the **most common IP address was 18.217.1.57**, so I filtered the traffic using:

```
ip.addr == 18.217.1.57 && http
```

While analyzing further, I noticed that there were many **DNS requests** for:

```
<some_gibberish>.redshrimpandherring.com
```

So I applied another filter:

```
ip.addr == 18.217.1.57 && dns.qry.name contains local
```

After that, I copied all the relevant packets and saved them into a **.txt file**. Then I used a **Python script generated by Claude AI** to decode the data.

I also referred to another person's write-up because I couldn't understand which flag was correct. I spent around **40 minutes** confused because my mind just wasn’t working at that moment.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://alham-rizvi.gitbook.io/alhamrizvi/picoctf-writeups/picoctf/forensics/pcap/wireshark-twoo-twooo-two-twoo...md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
