在web渗透测试中，信息侦察与收集相当重要，每个经验丰富的黑客都有自己独特的信息收集妙招，曾有幸参加过大牛们的信息收集交流，点子都非常赞。在秉承黑站思路第一的前提下，能合理的利用现有的优秀工具也是不错的选择，起码对新手而言，可以扩充思路。现在就记录一下Recon-ng 这款较新的信息侦察收集工具的使用。
一、安装
1.安装依赖文件dnspython,httplib2,python-0auth2
sudo pip install dnspython （也可以使用easy_install安装）
sudo pip install httplib2
git clone https://github.com/synedra/python-oauth2.git
cd python-oauth2/
sudo python setup.py install
2.安装recon-ng
git clone https://LaNMaSteR53@bitbucket.org/LaNMaSteR53/recon-ng.git
3.运行
cd recon-ng/ ./recon-ng.py
二、使用
与MSF的使用方法非常类似，插播一下msf使用基础流程，唤起回忆
(MSF 越来越深入人心咯~)
第一步：search name模块
第二步：use name模块
第三步：info 查看模块信息
第四步：show payloads 查看该模块可以使用的攻击载荷（为scanner的时候不需要）
第五步：set payload 载荷
第六步：show targets查看该攻击载荷使用的系统类型（为scanner的时候不需要）
第七步：set targets num 设置目标的系统类型
第八步：show options 查看需要设置的参数show advanced 列出所有高级配置选项
mso-hansi-font-family:"Times New Roman";mso-fareast-language:ZH-CN;" >第九步：set name
mso-hansi-font-family:"Times New Roman";mso-fareast-language:ZH-CN;" >设置参数
mso-hansi-font-family:"Times New Roman";mso-fareast-language:ZH-CN;" >第十步：exploit
mso-hansi-font-family:"Times New Roman";mso-fareast-language:ZH-CN;" >（为scanner
"Times New Roman";mso-fareast-language:ZH-CN;" >时用run
"Times New Roman";mso-fareast-language:ZH-CN;" >）
第十一步：session –l –v列出所有可用的交互会话以及详细信息
1. 模块介绍
在使用该工具前，有必要提及一下信息收集的常规步骤，以便如何使用这款工具。信息收集分为三步：侦察Reconnaissance、发现Discovery与汇报reporting。这也对应了该工具的三个模块
recon-ng > show modules
（1）. 侦察Reconnaissance
是一种被动的信息收集方式（passive reconnaissance），例如通过搜索引擎google hacker技巧收集目标的敏感信息
（2）.发现Discovery
是一种主动的信息收集方式（active reconnaissance），例如通过发送http请求包探测web服务指纹
（3）.汇报Reporting
Recon-ng提供两种格式的报表，html与csv
2. 模块使用范例
(1) web应用指纹识别
第一步：搜索指定模块
recon-ng > search whatweb
[*] Searching for 'whatweb'
Recon:
-------------------------------
recon/hosts/enum/http/whatweb
第二步：使用该模块
recon-ng > use recon/hosts/enum/http/whatweb
第三步：查看模块信息
recon-ng [whatweb] > info
Name:
WhatWeb Web Technologies scan
Author:
thrapt (thrapt@gmail.com) and Tim Tomes (@LaNMaSteR53)
Description:
Leverages WhatWeb.net to recognise web technologies being used.
Options:
Name Current Value Req Description
------- ------------- --- -----------
SOURCE db yes source of module input
VERBOSE True yes verbose output
Comments:
Source options: [ db | <hostname> | ./path/to/file | query <sql> ]
第四步：设置选参数
recon-ng [whatweb] > set SOURCE resources.infosecinstitute.com
SOURCE => resources.infosecinstitute.com
第五步：运行
recon-ng [whatweb] > run
注意：如果出现 [!] <urlopen error timed out> 的错误提示，可以修改全局参数SOCKET_TIMEOUT
recon-ng [whatweb] > back
recon-ng > show options
Name Current Value Req Description
-------------- ------------- --- -----------
COMPANY no target company name
DB_FILE ./data/data.db yes path to main database file
DOMAIN no target domain
KEY_FILE ./data/keys.db yes path to API key database file
PROXY False yes proxy all requestsPROXY_SERVER 127.0.0.1:8080 yes proxy server
REC_FILE ./data/cmd.rc yes path to resource file for 'record'
SOCKET_TIMEOUT 10 yes socket timeout in seconds
USER-AGENT Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; Trident/6.0) yes user-agent string
VERBOSE True yes verbose outputrecon-ng > set
SOCKET_TIMEOUT 20SOCKET_TIMEOUT => 20
recon-ng > use recon/hosts/enum/http/whatwebrecon-ng [whatweb] > set SOURCE resources.infosecinstitute.comSOURCE => resources.infosecinstitute.com
recon-ng [whatweb] > run
探测结果如下图所示
（2）公司职员信息收集
recon-ng > use recon/contacts/gather/http/jigsawrecon-ng [jigsaw] > info
Name:Jigsaw Contact Enumerator
Author:Tim Tomes (@LaNMaSteR53)Description:Harvests contacts from Jigsaw.com. This module updates the 'contacts' table of the database with theresults.
Options:
Name Current Value Req Description
-------- ------------- --- -----------
COMPANY yes target company name
KEYWORDS no additional keywords to identify company
VERBOSE True yes verbose outputrecon-ng [jigsaw] > set COMPANY google.com
recon-ng [jigsaw] > run
该模块是通过在搜索http://www.jigsaw.com/ 网站，收集公司组织架构信息，需要花费一段时间运行，你可以使用ctrl+c终止查询，搜索结果我们可以采用下面的方法导出来
recon-ng > use reporting/html_report
recon-ng [html_report] > info
Name:
HTML Report Generator
Author:
Tim Tomes (@LaNMaSteR53)
Description:
Creates a HTML report.
Options:
Name Current Value Req Description
-------- ------------- --- -----------
FILENAME ./data/results.html yes path and filename for report output
SANITIZE True yes mask sensitive data in the report
recon-ng [html_report] > set FILENAME /root/Desktop/result.html
FILENAME => /root/Desktop/result.html
recon-ng [html_report] > run
[*] Report generated at '/root/Desktop/result.html'.
我们打开result.html，可以看到收集到的以下信息
遗憾的是该模块使用的是http://www.jigsaw.com/网站中的信息，而国内网站基本没有收入进来，所以不适合做国内网站渗透信息收集。其实绝大多数好用的开源的被动的信息收集工具（passive reconnaissance）使用的信息源都不适合国内网站渗透信息收集，但可以参考这个思路，做一个国内版的。
（3）查看apache server-status页面是否可以访问
server-status页面会显示apache服务器的重要信息，如下图所示
recon-ng > use discovery/info_disclosure/http/server_statusrecon-ng [server_status] > info
Name:
Apache Server-Status Page Scanner
Author:
Tim Tomes (@LaNMaSteR53)
Description:
Checks hosts for a 'server-status' page.
Options:
Name Current Value Req Description
------- ------------- --- -----------
SOURCE db yes source of module input
VERBOSE True yes verbose output
Comments:
Source options: [ db | <hostname> | ./path/to/file | query <sql> ]
http://blog.sucuri.net/2012/10/popular-sites-with-apache-server-status-enabled.html
http://httpd.apache.org/docs/2.2/mod/mod_status.html
Google dork: intitle:"Apache Status" inurl:"server-status"
recon-ng [server_status] > set SOURCE apache.org
SOURCE => apache.org
recon-ng [server_status] > run
recon-ng [server_status] > run
[*] http://apache.org/server-status/ => 200. Possible Apache Status page found!
[*] https://apache.org/server-status/ => 200. Possible Apache Status page found![*] 2 Server Status pages found.
(4) 域名信息收集
recon-ng > use recon/hosts/gather/http/yahoo
recon-ng [yahoo] > set DOMAIN qq.comDOMAIN => qq.com
recon-ng [yahoo] > run
需要花费一段时间运行，可以使用ctrl+c终止查询，搜索结果同样可以采用html或csv的格式导出来，方法见 （2）公司职员信息收集
recon-ng [yahoo] > back
recon-ng > use reporting/html_report
recon-ng [html_report] > set FILENAME /Users/dani/Desktop/result_yahoo.html
FILENAME => /Users/dani/Desktop/result_yahoo.html
类似的域名搜索模块还有
recon/hosts/gather/http/netcraft
recon/hosts/gather/http/baidu
recon/hosts/gather/http/bingrecon/hosts/gather/http/google
(5)服务器指纹
recon-ng > use recon/hosts/enum/http/server_enum
recon-ng [server_enum] > set host apache.org
HOST => apache.org
recon-ng [server_enum] > run

(6) 查找robots.txt
详细的robots.txt会暴露敏感路径
recon-ng > use discovery/info_disclosure/http/robots
recon-ng [robots] > set SOURCE bus.61.com
SOURCE => bus.61.com
recon-ng [robots] > run
[*] http://bus.61.com/robots.txt => 200. robots.txt found!
[*] http://bus.61.com/sitemap.xml => 404
[*] http://bus.61.com/sitemap.xml.gz => 403
[*] https://bus.61.com/robots.txt => Error
[*] https://bus.61.com/sitemap.xml => Error
[*] https://bus.61.com/sitemap.xml.gz => Error
[*] 1 files found.
