# 简介
信息收集是渗透测试中首先要做的重要事项之一，目的是尽可能多的查找关于目标的信息，我们掌握的信息越多，渗透成功的机会越大。在信息收集阶段，我们主要任务是收集关于目标机器的一切信息，比如IP地址，开放的服务，开放的端口。这些信息在渗透测试过程中启到了至关重要的作用。为了实现这一目的，我们将在本章学习各种扫描技术、如SMB扫描、SSH服务扫描，FTP扫描、SNMP枚举、HTTP扫描以及WinRM扫描和暴力破解。
收集信息的方式主要有三种：
1、被动信息收集：这种方式是指在不物理连接或访问目标的时候，获取目标的相关信息，这意味着我们需要使用其他信息来源获得目标信息。比如查询whois信息。假设我们的目标是一个在线的Web服务，那么通过whois查询可以获得它的ip地址，域名信息，子域信息，服务器位置信息等。
2、主动信息收集：这种方式是指与目标建立逻辑连接获取信息，这种方式可以进一步的为我们提供目标信息，让我们对目标的安全性进一步理解。在端口扫描中，使用最常用的主动扫描技术，探测目标开放的端口和服务。
3、社会工程学：这种方式类似于被动信息收集，主要是针对人为错误，信息以打印输出、电话交谈、电子邮件等形式泄露。使用这种方法的技术有很多，收集信息的方式也不尽相同，因此，社会工程学本身就是一个技术范畴。
社会工程的受害者被诱骗发布他们没有意识到会被用来攻击企业网络的信息。例如，企业中的员工可能会被骗向假装是她信任的人透露员工的身份号码。尽管该员工编号对员工来说似乎没有价值，这使得他在一开始就更容易泄露信息，但社会工程师可以将该员工编号与收集到的其他信息一起使用，以便更快的找到进入企业网络的方法。
# 1、使用Metasploit进行被动信息收集
在本章中，我们将详细学习信息收集的各种被动和主动技术。首先，我们将学习分析最常用和最容易被忽视的被动信息收集技术，然后，我们将重点关注通过端口扫描获取信息。Metasploit 具有多种内置扫描功能，以及一些与之集成的第三方工具，以进一步增强端口扫描功能。我们将学习使用内置的扫描仪，以及一些与Metasploit 框架结合使用的第三方扫描工具。让我们开始吧。
我们将从公司域名开始收集信息，获取公司有关信息，收集子域名，检测蜜罐、收集电子邮件地址等。
Metasploit中有好几个信息收集模块，在本节中，我们将学习使用其中的一些模块，建议你自行探索学习所有的信息收集模块。
# DNS记录扫描和枚举
DNS扫描和枚举模块可用于从给定的DNS服务器收集有关域名的信息，执行各种DNS查询（如域传送，反向查询，SRV记录等）
1、程序位于auxiliary模块中，进入msfconsole后，我们可以使用use命令调用我们想要的模块，我们要使用的 auxiliary/gather/enum_dns模块。使用use auxiliary/gather/enum_dns 进入模块，输入info可以查看模块的信息，包括作者，描述，基本配置信息等。

# 邮箱信息收集
收集邮箱信息是渗透测试中常见的部分，它可以让我们了解互联网上目标的痕迹，以便用于后续的暴力攻击以及网络钓鱼等活动。
我们可以使用auxiliary/gather/search_email_collector模块，该模块是利用搜索引擎获取与目标有关的电子邮件信息。
msf5 > use auxiliary/gather/search_email_collector
msf5 auxiliary(gather/search_email_collector) > set DOMAIN packtpub.com

# 2、使用Metasploit进行主动信息收集
通常来说，通过扫描进行主动信息收集，从这一步开始，我们将直接与目标进行逻辑连接。
端口扫描是一个有趣的信息收集过程，它涉及对目标系统更深入的搜索，但是由于主动端口扫描涉及对目标系统直接访问，可能会被防火墙和入侵检测系统检测到。
在Metasploit框架中，有各种各样的端口扫描模块可供我们使用，从而允许我们准确的对目标系统进行探测。我们可以通过search portscan 命令查看这些模块。
msf5 > search portscan

# TCP 端口扫描
让我们从TCP端口扫描模块开始，看看我们能获取目标的哪些信息？
我们要使用的模块是use auxiliary/scanner/portscan/tcp
Tip：我们将利用此模块扫描渗透测试实验环境的网络，请遵守当地法律法规，请勿直接扫描互联网设备。
msf5 > use auxiliary/scanner/portscan/tcp
msf5 auxiliary(scanner/portscan/tcp) > set RHOSTS 192.168.177.0/24 //设置目标网络
RHOSTS => 192.168.177.0/24
msf5 auxiliary(scanner/portscan/tcp) > set THREADS 100 //设置线程数
THREADS => 100
msf5 auxiliary(scanner/portscan/tcp) > run
[+] 192.168.177.1: - 192.168.177.1:22 - TCP OPEN
[+] 192.168.177.1: - 192.168.177.1:21 - TCP OPEN
Tip：扫描器模块一般使用RHOSTS，表示扫描整个网络，而不是RHOST（单机）
当我们使用Metasploit模块的时候，可以使用show options查看所有可配置的选项，使用show missing查看必须要配置的选项。
msf5 auxiliary(scanner/portscan/tcp) > show options

# TCP SYN 扫描
相对普通的TCP扫描来说，SYN扫描速度更快，因为它不会完成TCP三次握手，而且可以在一定程度上躲避防火墙和入侵检测系统的检测。
使用的模块是auxiliary/scanner/portscan/syn，使用该模块，需要指定端口范围。
msf5 > use auxiliary/scanner/portscan/syn
msf5 auxiliary(scanner/portscan/syn) > set INTERFACE eth0 //设置网卡
INTERFACE => eth0
msf5 auxiliary(scanner/portscan/syn) > set PORTS 1-10000 //设置端口范围
PORTS => 1-10000
msf5 auxiliary(scanner/portscan/syn) > set THREADS 256 //设置线程数
THREADS => 256
msf5 auxiliary(scanner/portscan/syn) > set RHOSTS 192.168.177.0/24 //设置目标网络
RHOSTS => 192.168.177.0/24
msf5 auxiliary(scanner/portscan/syn) > run
# 3、使用Nmap进行端口扫描
Nmap是安全人员首选的强大网络扫描工具，我们将从初级到高级，详细分析Nmap的各种扫描技术。
你可以直接在msfconsole中运行Nmap，但是如果要将结果导入到Metasploit数据库中，需要使用-oX选项导出XML格式的报告文件，然后使用db_import命令将结果导入进来。
1、启动msfconsole，然后输入nmap
msf5 > nmap
[*] exec: nmap
Nmap 7.70 ( https://nmap.org )
Usage: nmap [Scan Type(s)] [Options] {target specification}
TARGET SPECIFICATION:
Can pass hostnames, IP addresses, networks, etc.
Ex: scanme.nmap.org, microsoft.com/24, 192.168.0.1; 10.0.0-255.1-254
-iL <inputfilename>: Input from list of hosts/networks
-iR <num hosts>: Choose random targets
--exclude <host1[,host2][,host3],...>: Exclude hosts/networks
--excludefile <exclude_file>: Exclude list from file
HOST DISCOVERY:
-sL: List Scan - simply list targets to scan
-sn: Ping Scan - disable port scan
-Pn: Treat all hosts as online -- skip host discovery
-PS/PA/PU/PY[portlist]: TCP SYN/ACK, UDP or SCTP discovery to given ports
-PE/PP/PM: ICMP echo, timestamp, and netmask request discovery probes
-PO[protocol list]: IP Protocol Ping
2、进行TCP扫描，使用-sT 参数，这是默认和最基本的扫描方式，它会完成TCP三次握手来检测目标机器上的端口。
msf5 > nmap -sT 192.168.177.144
[*] exec: nmap -sT 192.168.177.144

Nmap done: 1 IP address (1 host up) scanned in 5.31 seconds
msf5 >
Tip：当未指定端口范围的时候，nmap默认扫描常见的1000个端口。
3、进行TCP SYN扫描，使用-sS参数，SYN扫描不会建立完整的TCP三次握手过程，也称半开连接扫描，SYN扫描被认为是一种比较隐蔽的扫描技术。
msf5 > nmap -sS 192.168.177.144 -p 22-5000
[*] exec: nmap -sS 192.168.177.144 -p 22-5000
Starting Nmap 7.70 ( https://nmap.org ) at 2019-04-12 12:29 CST

Nmap done: 1 IP address (1 host up) scanned in 14.45 seconds
msf5 >
大多数情况下，TCP连接扫描和SYN扫描输出结果是相似的，唯一的区别是，SYN更难被防火墙和IDS检测到。当然现代的防火墙几乎都能捕获SYN扫描，-p参数设置我们想要扫描的端口范围。
4、UDP扫描使用-sU参数，用于识别目标机器上开放的UDP端口扫描技术，UDP扫描会发送空的(没有数据)UDP报头到目标端口，仅通过ICMP消息来判断目标端口是否开放。
msf5 > nmap -sU 192.168.177.144
[*] exec: nmap -sU 192.168.177.144

TIp：不指定端口范围的情况下，默认扫描常见的1000个UDP端口
我们分析了三种不同类型的nmap扫描，它们在渗透测试中非常有用。Nmap提供了许多种不同的扫描方是，这里我们只重点讨论这三种，即TCP连接扫描、SYN隐蔽扫描和UDP扫描。可以将Nmap的不同扫描选项组合到一起使用，已便对目标进行更高级和更复杂的扫描。
在渗透测试中，扫描过程可以提供很多有用的结果。扫描中收集的信息构成了后续渗透测试的基础，因此强烈建议你掌握扫描类型的相关知识，让我们更深入了解下我们刚刚学习的这些扫描技术。
TCP连接扫描是最基本的扫描技术，此扫描过程会与目标建立完整的TCP连接。它使用操作系统网络功能建立连接，扫描程序向目标发送SYN数据包，如果端口开放，目标会返回ACK消息。然后扫描程序向目标发送ACK报文，成功建立连接，这就是所谓的三次握手过程。连接打开后立即终止，这种技术有它的优点，但很容易被防火墙和IDS检测到。
SYN扫描是另一种类型的TCP扫描，但它不会与目标建立完整的连接。 它不使用操作系统的网络功能，而上生成原始IP包并监视响应报文。如果目标端口是开放的，目标会响应ACK消息，然后扫描程序会发送RST结束连接。因此又称为半开扫描。这也被认为是一种隐蔽扫描技术，可以避免被一些防火墙和IDS检测到。
UDP扫描是一种无连接扫描技术，因此，无论目标是否收到数据包，都不会返回信息给扫描程序。如果目标端口关闭，则扫描程序会收到ICMP端口不可达的消息。如果没有消息，扫描器会认为端口是开放的。由于防火墙会阻止数据包，此方法会返回错误结果，因此不会生成响应消息，扫描器会报告端口为打开状态。
让我们进一步探索Nmap扫描，学习如何将不同扫描类型组合到一起
# 操作系统和版本检测
除了端口扫描之外，Nmap还提供一些高级的选项，这些选项可以帮助我们获取目标的更多信息。其他使用最广泛的选项之一是操作系统识别选项：-O。可以帮助我们识别目标计算机的操作系统类型。
以下是操作系统识别扫描结果：

# 隐蔽扫描
有时候必须以隐蔽方式进行扫描，默认情况下，防火墙和IDS日志会记录你的IP，nmap中提供了-D选项来增加迷惑性。
此选项并不能阻止防火墙和IDS记录你的IP，只是增加迷惑性，它会通过添加其他IP地址，让目标以为是多个IP在攻击。比如，你添加了两个诱导IP，防火墙或IDS日志会显示数据包是从三个不同的IP地址发送的，一个是你的，其他两个是你添加的虚假地址。
msf5 > nmap -sT 192.168.177.144 -D 192.168.177.34,192.168.177.56
这个例子中-D后面的IP地址是虚假的IP地址，它会和原始IP地址一同出现在目标机器的网络日志文件中，这会迷惑对方的网络管理员，让他们以为这三个IP都是伪造的。但不能添加太多虚假IP地址，不然会影响扫描结果。因此，只要使用一定数量的地址就行。
# 4、使用db_nmap方式进行端口扫描
使用db_nmap的好处在于可以将结果直接存储到Metasploit数据库中，而不再需要db_import进行导入。
db_nmap命令是msfconsole中的一部分，所以只需要启动msfconsole并使用就好了。参数就和在命令行中单独使用nmap一样。
在第一章中，我们已经学习了db_nmap的一些基本用法，所以现在我们将了解一些更高级的特性。在下面的例子中，你将学习如何使用其中的一些特性。
msf5 > db_nmap -Pn -sTV -T4 --open --min-parallelism 64 --version-all 192.168.177.144 -p -
-Pn：跳过主机发现过程
-sTV：TCP扫描和检测开放端口服务版本信息
-T4：设置时间模板，加速扫描
--open：只显示开放端口
--min-parallelism：探测报文的并发数
--version-all：尝试每个探测，保证对每个端口尝试每个探测报文，获取服务更具体的版本
-p -：表示扫描所有的端口（1-65535）
输出结果如下：
msf5 > db_nmap -Pn -sTV -T4 --open --min-parallelism 64 --version-all 192.168.177.144 -p -

# Nmap 脚本引擎
Nmap脚本引擎（NSE）是Nmap最强大和最灵活的特性之一，它可以将Nmap转为漏洞扫描器使用。NSE有超过600个脚本，分为好几类，有非侵入式的，也有侵入式的，比如暴力破解，漏洞利用和拒绝服务攻击。你可以在Kali的/user/share/nmap/scripts目录中找到这些脚本。或者用locate搜索*.nse也可以找到。
root@osboxes:~# locate *.nse
/usr/share/nmap/scripts/targets-xml.nse
/usr/share/nmap/scripts/teamspeak2-version.nse
/usr/share/nmap/scripts/telnet-brute.nse

/usr/share/nmap/scripts/tso-enum.nse
/usr/share/nmap/scripts/unittest.nse
/usr/share/nmap/scripts/unusual-port.nse
它的用法如下：
nmap --script <scriptname> <host ip>
在db_nmap中同样可以使用，我们试试用NSE脚本来查找目标的HTTP/HTTPS漏洞

# 5、基于ARP的主机发现
通过ARP请求可以枚举本地网络中的存活主机，为我们提供了一种简单而快速识别目标方法。
当攻击者和目标机器处于同一个局域网时，可以通过执行ARP扫描发现主机
1、使用ARP扫描模块（ auxiliary/scanner/discovery/arp_sweep），设置目标地址范围和并发线程，然后运行。
msf5 > use auxiliary/scanner/discovery/arp_sweep
msf5 auxiliary(scanner/discovery/arp_sweep) > set RHOSTS 192.168.177.0/24
RHOSTS => 192.168.177.0/24
msf5 auxiliary(scanner/discovery/arp_sweep) > set THREADS 256

# 6、UDP 服务识别
UDP服务扫描模块运行我们检测模板系统的UDP服务。由于UDP是一个无连接协议（不面向连接），所以探测比TCP困难。使用UDP服务探测模块可以帮助我们找到一些有用的信息。
选择 auxiliary/scanner/discovery/udp_sweep模块，设置目标范围，然后运行扫描即可
msf5 > use auxiliary/scanner/discovery/udp_sweep
msf5 auxiliary(scanner/discovery/udp_sweep) > set RHOSTS 192.168.177.0/24
RHOSTS => 192.168.177.144/24

# 7、SMB扫描和枚举
多年来，SMB协议（一种在 Microsoft Windows系统中使用网络文件共享的协议）已被证明是最容易被攻击的协议之一，它允许攻击者枚举目标文件和用户，甚至远程代码执行。
使用无需身份验证的SMB共享枚举模块，可以帮助我们收集一些有价值的信息，比如共享名称，操作系统版本等。
模块名：auxiliary/scanner/smb/smb_enumshares
msf5 > use auxiliary/scanner/smb/smb_enumshares
msf5 auxiliary(scanner/smb/smb_enumshares) > set RHOSTS 192.168.177.144
RHOSTS => 192.168.177.144
msf5 auxiliary(scanner/smb/smb_enumshares) > run

[*] 192.168.177.144: - Scanned 1 of 1 hosts (100% complete)
[*] Auxiliary module execution completed
SMB共享枚举模块在后续的攻击阶段也非常有用，通过提供凭据，可以轻松的枚举共享和文件列表
msf5 auxiliary(scanner/smb/smb_enumshares) > set SMBUSER vagrant
SMBUSER => vagrant
msf5 auxiliary(scanner/smb/smb_enumshares) > set SMBPASS vagrant
SMBPASS => vagrant
msf5 auxiliary(scanner/smb/smb_enumshares) > set RHOSTS 192.168.177.144

msf5 auxiliary(scanner/smb/smb_enumshares) >
Metasploit还提供其他的一些SMB扫描模块，让我们看看其他模块的用法。
3、SMB版本检测模块可以检测SMB的版本
msf5 > use auxiliary/scanner/smb/smb_version
msf5 auxiliary(scanner/smb/smb_version) > set RHOSTS 192.168.177.144
RHOSTS => 192.168.177.144

4、用户枚举模块可以通过SAM RPC服务枚举哪些用户存在
msf5 > use auxiliary/scanner/smb/smb_enumusers
msf5 auxiliary(scanner/smb/smb_enumusers) > set SMBUSER vagrant
SMBUSER => vagrant
msf5 auxiliary(scanner/smb/smb_enumusers) > set SMBPASS vagrant

5、SMB登录检测模块可以测试SMB登录
msf5 > use auxiliary/scanner/smb/smb_login
msf5 auxiliary(scanner/smb/smb_login) > set RHOSTS 192.168.177.144
RHOSTS => 192.168.177.144

7、其他的模块，都在 auxiliary/scanner/smb/中，可以敲 TAB键查看，你可以一个个学习，这里就不一一举例讲解。
msf5 > use auxiliary/scanner/smb/
use auxiliary/scanner/smb/impacket/dcomexec
use auxiliary/scanner/smb/smb1
use auxiliary/scanner/smb/smb_login
.....
# 8、SSH 版本扫描和检测
SSH是一个广泛使用的远程登录程序。它使用强大的加密提供身份认证和保证机密性。在本节中，我们将通过SSH版本扫描模块，确定目标使用的SSH版本，确定是否为易受攻击的SSH版本，如果是，我们可以利用它。
在之前的扫描中，我们发现目标机器开放了TCP 22端口，这也是SSH的默认端口，我们用SSH版本探测模块来获取目标系统上运行的SSH版本信息。
1、模块名称：auxiliary/scanner/ssh/ssh_version
msf5 > use auxiliary/scanner/ssh/ssh_version
msf5 auxiliary(scanner/ssh/ssh_version) > set RHOSTS 192.168.177.144
RHOSTS => 192.168.177.144
msf5 auxiliary(scanner/ssh/ssh_version) > run
[+] 192.168.177.144:22 - SSH server version: SSH-2.0-OpenSSH_7.1 ( service.version=7.1 service.vendor=OpenBSD service.family=OpenSSH service.product=OpenSSH service.cpe23=cpe:/a:openbsd:openssh:7.1 service.protocol=ssh fingerprint_db=ssh.banner )
[*] 192.168.177.144:22 - Scanned 1 of 1 hosts (100% complete)
[*] Auxiliary module execution completed
msf5 auxiliary(scanner/ssh/ssh_version) >
当然这里的RHOSTS 选项也可以指定为网络地址，从而扫描整个网段。
获取版本信息之后，我们就可以搜索该版本的漏洞。
2、测试常用口令登录SSH，可以使用SSH登录测试模块
msf5 > use auxiliary/scanner/ssh/ssh_login
msf5 auxiliary(scanner/ssh/ssh_login) > set RHOSTS 192.168.177.144
RHOSTS => 192.168.177.144
msf5 auxiliary(scanner/ssh/ssh_login) > set USERNAME user
USERNAME => user
msf5 auxiliary(scanner/ssh/ssh_login) > set PASS_FILE /root/password.lst
PASS_FILE => /root/password.lst
msf5 auxiliary(scanner/ssh/ssh_login) > run
[*] Scanned 1 of 1 hosts (100% complete)
[*] Auxiliary module execution completed
3、如果登录成功了，可以用sessions 查看会话和与目标进行会话交互
msf5 auxiliary(scanner/ssh/ssh_login) > sessions
Active sessions
===============
No active sessions.
# 9、FTP扫描
使用FTP扫描模块对网络中所有的FTP服务进行版本扫描
FTP版本扫描模块运行我们检测正在运行的FTP版本
1、使用 auxiliary/scanner/ftp/ftp_version模块，设置好扫描范围和线程，就可以运行扫描了。
msf5 > use auxiliary/scanner/ftp/ftp_version
msf5 auxiliary(scanner/ftp/ftp_version) > set RHOSTS 192.168.177.0/24
RHOSTS => 192.168.177.0/24
msf5 auxiliary(scanner/ftp/ftp_version) > set THREADS 256
THREADS => 256

# 10、SMTP枚举
SMTP服务偶两个允许枚举用户的内部命令：VRFY（确认有效用户名）和EXPN（显示用户的实际地址，别名和邮件列表）
SMTP用户枚举模块通过实现这些SMTP命令从而枚举有效的用户列表
默认情况下，SMTP枚举模块使用unix_users.txt(文件位于： /usr/share/metasploit- framework/data/wordlists/)文件作为字典，你也可以指定自己的字典文件。切换到auxiliary/scanner/smtp/smtp_enum模块，设置好目标和线程，然后开始。
msf5 > use auxiliary/scanner/smtp/smtp_enum
msf5 auxiliary(scanner/smtp/smtp_enum) > set RHOSTS 192.168.177.145

# 11、SNMP枚举
简单网络管理协议（SNMP）是用于管理网络设备的协议，比如监控设备的状态信息，接口信息，网络接口的数据吞吐量等。通过SNMP扫描器可以找到特定系统的大量信息。本节中，我们将学习如何使用它。
Metasploit 有一个专门用于扫描 SNMP 设备的内置辅助模块。在进行攻击之前必须先了解它。首先，团体字符串（只读/读写）在可以在设备本身上挖掘或修改的信息类型中起着重要作用。管理信息库 (MIB) 接口允许我们查询设备和提取信息。
Tip：如果目标系统为Windows且配置了SNMP（通常是RO/RW团体字符串），我们可以提取系统重启时间，系统上的用户名，系统网络信息，运行的服务等各种有价值的信息。
当通过SNMP查询时候，可以通过MIB API进行设备信息提取。Metasploit在其数据库中加载默认MIB列表，它们用于查询设备获取更多信息。
1、通过SNMP登录模块可以通过公共团体名登录到目标系统。

# 12、HTTP扫描
超文本传输协议（HTTP）是一个应用层协议，它是万维网通信的基础。它被众多的应用程序使用，从物联网（IoT）设备到移动应用程序。它也是搜索漏洞的好地方。
HTTP SSL证书检测模块可以检测Web服务器的证书。
Robots.txt内容检测模块可以搜索robots.txt文件并分析里面的内容。
如果服务端允许未授权的PUT请求方法，则可以将任意的Web页面插入到网站目录中，从而导致执行破坏性的代码或者往服务器填充垃圾数据，从而造成拒绝服务攻击。
Jenkins-CI HTTP扫描模块可以枚举未授权的Jenkins-CI服务。
1、检测目标的HTTP SSL证书
msf5 > use auxiliary/scanner/http/cert
msf5 auxiliary(scanner/http/cert) > set RHOSTS 192.168.177.144
RHOSTS => 192.168.177.144
msf5 auxiliary(scanner/http/cert) > set RPORT 8383
RPORT => 8383
msf5 auxiliary(scanner/http/cert) > run

[*] 192.168.177.144:8383 - Scanned 1 of 1 hosts (100% complete)
2、检测robots.txt文件
msf5 > use auxiliary/scanner/http/robots_txt
msf5 auxiliary(scanner/http/robots_txt) > set PATH /mutillidae
PATH => /mutillidae
msf5 auxiliary(scanner/http/robots_txt) > set RHOSTS 192.168.177.145
RHOSTS => 192.168.177.145

# 13、WinRM扫描和爆破
Windows远程管理（WinRM）是WS-Management协议的Microsoft实现。该协议是基于简单对象访问协议（SOAP）的、防火墙友好的标准协议，使来自不同供应商的硬件和操作系统能够互相交互。
WinRM身份认证方法检测模块通过向目标发现HTTP/HTTPS请求，检测是否为WinRM服务，如果是，将会检测支持的身份认证方法。
通过SMB_login模块可以检索目标的登录凭证。我们可以用WinRM命令运行模块测试是否可以通过WinRM服务运行Windows命令。
1、WinRM身份认证检测
msf5 > use auxiliary/scanner/winrm/winrm_auth_methods
msf5 auxiliary(scanner/winrm/winrm_auth_methods) > set RHOSTS 192.168.177.144
RHOSTS => 192.168.177.144
msf5 auxiliary(scanner/winrm/winrm_auth_methods) > run

[*] Scanned 1 of 1 hosts (100% complete)
[*] Auxiliary module execution completed
msf5 auxiliary(scanner/winrm/winrm_auth_methods) >
2、使用WinRM命令运行模块
msf5 > use auxiliary/scanner/winrm/winrm_cmd
msf5 auxiliary(scanner/winrm/winrm_cmd) > set CMD hostname
CMD => hostname
msf5 auxiliary(scanner/winrm/winrm_cmd) > set RHOSTS 192.168.177.144
RHOSTS => 192.168.177.144
msf5 auxiliary(scanner/winrm/winrm_cmd) > set USERNAME Administrator
USER => Administrator
msf5 auxiliary(scanner/winrm/winrm_cmd) > set PASSWORD vagrant

可以看到，我们成功在目标机上执行了命令。
# 14、与Nessus结合使用
到目前为止，我们已经了解了端口扫描的基础知识，以及学会了Nmap的使用。通过其他一些工具的学习，进一步提高了扫描和信息收集的技术。接下来将介绍其他几种扫描目标可用服务和端口的工具，这些工具还可以帮助我们确定特定服务和端口可能存在的漏洞类型。
Nessus是使用最广泛的漏洞扫描器之一，它可用通过扫描目标发现漏洞并生成详细的报告。Nessus是渗透测试中非常有用的工具。你可用使用它的GUI版本，也可以在Metasploit控制台中使用它。本书主要介绍在msfconsole中使用它。
要使用Nessus需要先去Nessus官网注册并取得Licenses。你可以使用Nessus家庭版，此授权是免费的，它允许你扫描个人家庭网络（小于16个IP地址）。然后下载软件安装包进行安装。在Kali中需要下载.deb格式的包，然后使用dpkg -i 进行安装。

安装完成之后，启动Nessus服务
root@osboxes:~/Downloads# systemctl start nessusd.service
根据提示，使用浏览器打开网址https://osboxes:8834/或者https://127.0.0.1:8834进行配置
1、设置用户名和密码：
2、选择Home,Professional or Manager，填写激活密钥进行授权激活。
3、激活完成后，Nessus还会安装一系列组件，等待安装完成(需要一段时间，请耐心等待)
安装完成后，就可以进行下一步操作了。
1、在msfconsole里面载入nessus组件。
msf5 > load nessus //载入nessus组件
[*] Nessus Bridge for Metasploit
[*] Type nessus_help for a command listing
[*] Successfully loaded plugin: Nessus
msf5 >
2、输入nessus_help命令，可以查看可用参数和帮助信息
msf5 > nessus_help
Command Help Text
------- ---------
Generic Commands
----------------- -----------------
nessus_connect Connect to a Nessus server
nessus_logout Logout from the Nessus server
nessus_login Login into the connected Nesssus server with a different username and password
nessus_save Save credentials of the logged in user to nessus.yml
nessus_help Listing of available nessus commands
nessus_server_properties Nessus server properties such as feed type, version, plugin set and server UUID.
nessus_server_status Check the status of your Nessus Server
nessus_admin Checks if user is an admin
nessus_template_list List scan or policy templates
nessus_folder_list List all configured folders on the Nessus server
nessus_scanner_list List all the scanners configured on the Nessus server
Nessus Database Commands
3、连接到Nessus服务，使用nessus_connect NessusUser:NessusPassword@127.0.0.1命令。
msf5 > nessus_connect nessusroot:Passw0rd@127.0.0.1 //连接到 Nessus 服务
[*] Connecting to https://127.0.0.1:8834/ as nessusroot
[*] User nessusroot authenticated successfully.
msf5 >
4、使用 nessus_policy_list可用列出Nessus服务上的所有扫描策略。如果没有，需要先在WebUI界面中创建策略。
msf5 > nessus_policy_list
[-] No policies found
msf5 >
提示没有策略，我们去创建一个
我们选择新建一个Basic Network Scan策略
配置好相关的参数，然后点保存
回到msfconsole里面再次执行nessus_policy_list就看看到了
msf5 > nessus_policy_list

5、创建nessus扫描，使用nessus_scan_new --help查看命令帮助信息：
msf5 > nessus_scan_new --help
[*] Usage:
[*] nessus_scan_new <UUID of Policy> <Scan name> <Description> <Targets>
[*] Use nessus_policy_list to list all available policies with their corresponding UUIDs
msf5 >
6、创建扫描
msf5 > nessus_scan_new 731a8e52-3ea6-a291-ec0a-d2ff0619c19d7bd788d6be818b65 Metasploitable3 Windows_Machine 192.168.177.144

# 16、与OpenVAS结合
OpenVAS（ Open Vulnerability Assessment System）是Nessus项目的分支。是一个免费开源的漏洞扫描和漏洞管理工具。也是当前使用最为广泛的漏洞扫描和管理开源解决方案。
1、在Kali上安装 OpenVAS
root@osboxes:~# apt install openvas -y
2、设置openvas，包括下载规则，创建管理员用户和服务。
root@osboxes:~# openvas-setup //这一步会下载很多东西，请耐心等待
