网络安全学习之利用Metasploit进行信息收集

基于TCP协议收集主机信息

使用Metsploit中的nmap 和arp_sweep 收集主机信息

msf中也有类似nmap功能的工具,名字是 db_nmap,用法同 nmap一样,如下所示:

msf6 > db_nmap -sS192.168.1.106  ### SYN扫描,用法同nmap里的nmap -sS 192.168.1.106[*] Nmap: Starting Nmap 7.93( https://nmap.org ) at 2024-08-03 16:12 CST
[*] Nmap: Nmap scan report for192.168.1.106
[*] Nmap: Host is up (0.00019s latency).
[*] Nmap: Not shown: 995 closed tcp ports (reset)[*] Nmap: PORT     STATE SERVICE
[*] Nmap: 22/tcp   openssh[*] Nmap: 88/tcp   open  kerberos-sec

基于snmp协议收集信息

需要先修改靶机上的snmp服务配置,因为snmp服务默认是不对外开放的

root@metasploitable:~# vim /etc/default/snmpd
找到下面这一行
SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid 127.0.0.1'
将下面行中的 127.0.0.1 修改为 0.0.0.0
SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid 0.0.0.0'

修改完后,保存退出,并重启snmpd服务

root@metasploitable:~# /etc/init.d/snmpd restart
Restarting network management services: snmpd.

其他好用的snmp枚举工具

SNMP 枚举工具snmpwalk

snmpwalk是一个SNMP应用程序。它使用SNMP的GETNEXT请求,查询指定的所有OID(SNMP协议中的对象标识)树信息,并显示给用户。

a) –h 显示帮助
b) –v 1|2c|3 指定SNMP协议版本
c) –V 显示当前SNMPWALK命令行版本
d) –r RETRIES 指定重试次数,默认为0次。
e) –t TIMEOUT 指定每次请求的等待超时时间,单为秒,默认为3秒。
f) –Cc 指定当在WALK时,如果发现OID负增长将是否继续WALK。
2. V1、V2C选项
a) –c COMMUNITY 指定共同体字符串
3. V3选项
a) –l LEVEL 指定安全级别:noAuthNoPriv|authNoPriv|authPriv
b) –u USER-NAME 安全名字
c) –a PROTOCOL 验证协议:MD5|SHA。如果-l指定为authNoPriv或authPriv时才需要。
d) –A PASSPHRASE 验证字符串。如果-l指定为authNoPriv或authPriv时才需要。
e) –x PROTOCOL 加密协议:DES。如果-l指定为authPriv时才需要。
f) –X PASSPHRASE 加密字符串:如果-l指定为authPriv时才需要。

基于SMB协议收集信息

SMB概述:服务器消息块(Server Message Block),又称为网络文件共享系统(Common Internet File System) ,一种应用层网络传输协议,由微软开发,主要功能是是网络上的机器能够共享计算机文件、打印机、串行端口和通讯等资源。
经过unix服务器厂商重新开发后,它可用于连接unix和windows客户机,执行打印和文件共享等任务。
