Kali安全渗透教程第9.5课:使用Easy-Creds工具攻击无线网络

Easy-Creds是一个菜单式的破解工具。该工具允许用户打开一个无线网卡,并能实现一个无线接入点攻击平台。Easy-Creds可以创建一个欺骗访问点,并作为一个中间人攻击类型运行,进而分析用户的数据流和账户信息。它可以从SSL加密数据中恢复账户。

(1)从https://github.com/brav0hax/easy-creds网站下载Easy-Creds软件包,其软件包名为easy-creds-master.zip。

(2)解压下载的软件包。执行命令如下所示:

root@localhost:~# unzip easy-creds-master.zip
Archive: easy-creds-master.zip
bf9f00c08b1e26d8ff44ef27c7bcf59d3122ebcc
  creating: easy-creds-master/
 inflating: easy-creds-master/README
 inflating: easy-creds-master/definitions.sslstrip
 inflating: easy-creds-master/easy-creds.sh
 inflating: easy-creds-master/installer.sh

从输出的信息中,可以看到Easy-Creds软件包被解压到easy-creds-master文件中。从以上信息中,可以看到在easy-creds-master文件中有一个installer.sh文件,该文件就是用来安装Easy-Creds软件包的。

(3)安装Easy-Creds软件包。在安装Easy-Creds软件包之前,有一些依赖包需要安装。这些依赖包,可以参考easy-creds-master文件中的README文件安装相关的依赖包。然后,安装Easy-Creds包。执行命令如下所示:

root@kali:~# cd easy-creds/
root@kali:~/easy-creds# ./installer.sh

以上信息显示了安装Easy-Creds包的详细过程。在该过程中,会检测easy-creds的依赖包是否都已安装。如果没有安装,此过程中会安装。Easy-Creds软件包安装完成后,将显示happy hunting!信息。

【实例9-4】使用Easy-Creds工具破解无线网络。具体操作步骤如下所示。

(1)启动Easy-Creds工具。执行命令如下所示:

root@localhost:~/easy-creds-master#./easy-creds.sh

以上输出的信息显示了Easy-Creds工具的攻击菜单。

(2)这里选择伪AP攻击,输入编号3。将显示如下所示的信息:

Choice: 3

图9.34 有效的窗口

(4)当有用户连接Wifi接入点时,Easy-Creds将自动给客户端分配一个IP地址,并且能够访问互联网。如果在互联网上访问一个安全网址时,该工具将除去SSL并删除安全连接并在后台运行。所以,能够读取到客户端登录某个网站的用户名和密码。如图9.34所示,捕获到一个登录http://www.live.com网站的用户名和密码。其用户名为test@live.com,密码为qwert。

(5)此时在Easy-Creds的主菜单中选择数据恢复,输入编号4,如下所示:

At any time, ctrl+c to cancel and return to the main menu
1\. Prerequisites & Configurations
2\. Poisoning Attacks
3\. FakeAP Attacks
4\. Data Review
5\. Exit
q. Quit current poisoning session
Choice: 4

(6)选择数据恢复后,将显示如下所示的信息:

/root/easy-creds-master/easy-creds-2014-07-24-1722/ettercap2014-07-24-1724.eci
Enter the full path to your ettercap.eci log file:

从输出信息中,可以看到Ettercap日志文件的保存位置。

(8)此时输入ettercap.eci日志文件的全路径。这里只需要通过复制并粘贴提供的整个Ettercap路径就可以了。如下所示:

Enter the full path to your ettercap.eci log file: /root/easy-creds-master/easy-creds-2014-07-24-1722/ettercap2014-07-24-1724.eci

输入以下路径后,将显示如图9.35所示的界面。
