OWASP Amass是一个开源工具，用于进行信息收集和网络映射，帮助发现攻击面和外部资产。它包括多个子命令如`intel`、`enum`、`viz`等，用于情报收集、DNS枚举、网络可视化等。用户可以通过配置文件定制数据源和输出，并能使用`track`和`db`子命令跟踪和管理数据。Amass生成的输出文件可在指定目录保存，便于后续枚举和分析。
OWASP Amass项目使用开源信息收集和主动侦察技术，对攻击面和外部资产发现进行网络映射。

输出结果保存
mass在枚举过程中输出多个文件（例如日志文件）。如果您没有使用数据库服务器来存储网络图形信息，那么Amass会在输出目录中创建一个基于文件的图形数据库。在未来的枚举过程中，以及在利用跟踪和可视化等功能时，将再次使用这些文件。
默认情况下，输出目录是在操作系统默认根目录中创建的，用于用户特定的配置数据，名为*amass*。如果这不适合您的需要，那么可以指示子命令使用**-dir**标志在其他位置创建输出目录。
如果您决定使用Amass配置文件，当将其放入输出目录并命名为 config.ini 时，将自动发现它。
