通过搜索证书透明度日志来发现子域
什么是CT？
证书透明度（CT）是实验性IETF标准。其目的是允许公众审核由证书颁发机构（CA）创建的证书。TLS的弱点来自浏览器隐式信任的大量CA。如果这些CA中的任何一个要为域恶意创建新证书，则您的浏览器将信任它。CT为TLS证书信任增加了好处：公司可以监视谁在为其所拥有的域创建证书。它还允许浏览器验证给定域的证书是否在公共日志记录中。
这些日志最终成为渗透测试人员和红色团队的金矿信息。

ct-exposer有什么用？
ct-exposer会查询给定域的CT日志，然后尝试对这些域进行DNS查找，以查看DNS中存在哪些域。根据我的经验，到目前为止，我已经找到了许多不在“ site:domain.com” google搜索中的子域。请记住，无法解析的域可以是旧域，也可以是仅内部域（例如：您需要访问内部DNS服务器才能解析它们）。
安装
pip3 install -r requirements.txt
用法
usage: ct-exposer.py [-h] -d DOMAIN [-u] [-m]
optional arguments:
-h, --help show this help message and exit
-d DOMAIN, --domain DOMAIN
domain to query for CT logs, ex: domain.com
-u, --urls ouput results with https:// urls for domains that
resolve, one per line.
-m, --masscan output resolved IP address, one per line. Useful for
masscan IP list import "-iL" format.
例如
python3 ct-exposer.py -d teslamotors.com
