# Prenote: As all of these challenges were similar, we decided to combine these under one page.

## Flag 1

nmap all ports to see port 4994 is open, just nc to it to get flag

### flag :zh3r0{pr05\_d0\_full\_sc4n5}

## Flag 2

Going back to port 324 (ftp)

the flag is in .../.../.flag

### flag: zh3r0{You\_know\_your\_shit}

## Flag 3

curling port 22 robots.txt gives you a string in base58, decode to get /clue3349203.txt, curl that to get a lot of jsfuck, decode that to get an employee id, and then use that on port 4994 to get the flag

### flag: zh3r0{y0ur\_b0nu5\_i5\_p4id}

## Flag 4

if we scan port 324, we can see it is an ftp server, which allows anonymous login.

ls -a ing gives us a ... dir (wow thanks hq), and then cding into it and ls -a ing again gives us a .stayhidden file. reading this gives us another employee id, which we can use to login to port 4994 again.

### flag: zh3r0{y0ur\_s4l4ry\_wa5\_cr3dit3d}

## Flag 5

nmap, see http port on port 22, curl it to get flag

### zh3r0{shouldve\_added\_some\_filter\_here}

# 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://the-winrars.gitbook.io/writeups/2020-writeups/zh3r0-ctf/flag-series.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.
