# FTP - ブルートフォース攻撃
Hydra、Nmapのサービス列挙、認証情報の検証、匿名アクセス確認、許可されたパスワード監査のためのFTPブルートフォーステストノート。
1. 次のコマンドを実行して [Nmap](/ja/reconnaissance/nmap.md) FTPのバージョンを確認し、既知の脆弱性を調べるには:
```bash
nmap -sCV -p21 127.0.0.1
```
2. インストールされているバージョンは **7.93** で、既知の脆弱性は検出されません。
3. 次のコマンドでブルートフォース攻撃を実行します **Hydra**。小文字の `-l` または `-p` はユーザー名またはパスワードが固定値であることを意味し、大文字の `-L` または `-P` はHydraが値をファイルから読み込むことを意味します。
```bash
hydra -l jordan -P /usr/share/wordlists/rockyou.txt ftp://127.0.0.1 -t 15
```
4. 有効な認証情報が見つかります。
**一般的なユーザー名とパスワードのワードリストを使ったFTPブルートフォース**

## 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/ja/ports-and-services/ftp-21/ftp-brute-force-attack.md?ask=&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.
