目标站点与子域名
目标站点与子域名
在红队行动中，目标站点往往是提供的有限信息之一，例如 raven-med.local，而我们需要从这个点入手。有了目标站点，我们可以进一步枚举其子域名，得到其面向公网的IT资产。考虑到raven-med.local是一个虚构的制造公司，并且该域名尚未被注册，此处我们以SmartBear公司 （https://smartbear.com）作为教学案例。
目标站点
对于目标站点本身，我们也是有诸多内容可以做的。需要提醒的是，在当前阶段无需进行主动侦查，例如使用扫描器对目标站点进行目录爆破等，这至少在我们充分进行了被动侦查之后再做。我们发现，该公司是一家计算机软件开发公司，并且我们从图片中可以看到有多个导航栏，例如产品、解决方案、资源、职业生涯等。这些都值得我们手动浏览一遍。这些对于我们有什么意义呢？例如通过了解产品，我们可以得知该公司的产业线，通过了解职业生涯信息，我们可以了解到该公司目前哪些岗位可能有空缺，以及从岗位描述中提取有效信息等等。
尽管我们没有使用主动扫描器，但我们依旧可以了解到该站点的一些信息，例如使用 shodan 搜索引擎。
此外，我们还可以查询该站点的DNS信息，但需要注意的是，不同的DNS服务器可能返回不同结果。

除了提供的站点外，我们还可以去枚举目标的子域名。因为子域名的数量往往比较庞大，对于企业来说，他们自己可能都不清楚自己有多少子域名，对于那些不常被关照的子域名，往往可能就是最脆弱的地方。对于主域名以及常用的子域名，公司往往即使更新公开服务的版本、修复漏洞，对于那些可能被遗忘的，情况则恰恰相反。枚举子域名的方法既有主动搜集，也有被动搜集。主动搜集例如使用字典来爆破枚举，被动搜集则利用了庞大的OSINT信息。接下来笔者来推荐2款子域名枚举的工具。
Sublist3r
这是一款老牌子域名枚举工具，经典且可靠。使用方法也很简单，执行命令sublist3r -d [域名] 即可。如果我们用其来枚举SmartBear公司的子域名，是这样的：
在这些结果中，我们可以找到该公司的VPN域名站点、Staging站点等。
OneForAll
地址：https://github.com/shmilylty/OneForAll
这款国产的工具也是很好用的，使用方法也是很简单。在安装完之后，执行命令 python3 oneforall.py --target [域名] 即可。
└─# python3 oneforall.py --target smartbear.com --fmt json run
OneForAll is a powerful subdomain integration tool
