subdomain-scanner

使用Golang编写的子域名检测程序,特点就是快、快、快。

扫描速度依赖于网络环境。1Mb带宽,200个goroutine,稳定1700左右/s的扫描速度。

默认为谷歌的DNS服务器,可自行配置其它DNS。

Change Log

  • [2018-12-03]
    • 更好的参数调用提示
  • [2018-12-01]
    • 支持DNS域传送
    • 泛域名识别+扫描(泛域名得到的ip加入黑名单,继续爆破非黑名单ip)
  • [2018-11-30]
    • 重构并发逻辑
    • go官方的net包,不够完善,好多RFC都不支持,比如RFC 4592,所以使用了一个第三方包来做dns解析,提升扫描效率。
  • [2018-11-27]
    • Demo雏形

TODO

  • 可选dns服务器
  • 自定义字典
  • 并发扫描
  • 泛域名识别+扫描(泛域名得到的ip加入黑名单,继续爆破非黑名单ip)
  • 支持DNS域传送
  • 从文件中获取需要检测的域名
  • 支持DNS AAAA,ipv6检测
  • 深度扫描(多级子域名检测)
  • 自定义导出格式、计划支持txt、json等
  • 更友好的参数调用提示
  • 支持api接口调用
