Kali Linux渗透测试之服务扫描(一)——Banner、服务识别、操作系统识别

热度:20   发布时间:2023-12-25 06:57:17.0

服务扫描:

不能简单的通过端口号来识别服务,目标系统开放80端口不一定开放着http服务,要通过对目标系统进行服务扫描,来识别开放的端口后面到底是什么服务,运行什么样的应用;

1. 服务扫描——Banner(简单但不准确)

  • 通过连接服务器的端口,使其返回的banner信息,可能查不到,也可能是管理员伪造的;
  • 通过软件开发商,软件名称,服务类型,版本号(直接发现已知的漏洞和弱点);
  • 对于Banner信息的捕获,需要建立完整的TCP连接;
  • 另类服务识别方法:1. 特征行为和响应字段; 2.  不同的响应可用于识别底层操作系统;

>>> banner.recv(4096)
'220 WIN-N7TAB1239LM.st13.com Winmail Mail Server ESMTP ready\r\n'
>>> banner.close()
>>> exit()

 (2)socket——用于连接网络服务

root@root:~# python
Python 2.7.14+ (default, Mar 13 2018, 15:23:44) 
[GCC 7.3.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import socket       #导入socket模块
>>> banner=socket.socket(socket.AF_INET,socket.SOCK_STREAM)  #SOCK_STREAM表示为TCP连接<
>>> banner.connect(("192.168.37.128",25))    #连接的IP地址和端口
>>> banner.recv(4096)                        #接收返回包大小
'220 WIN-N7TAB1239LM.st13.com Winmail Mail Server ESMTP ready\r\n' #获取到的Banner信息
>>> banner.close()            #关闭连接
>>> exit()

在很多情况下,系统的banner信息不允许抓取,recv函数无返回将会被挂起;针对这个问题,写如下脚本进行处理:

#!/usr/bin/python 
# -*- coding: utf-8 -*-
#Author:橘子女侠
#Time:2019/04/14
#该脚本用于实现Banner信息的扫描,如果Banner信息不能获取,则passimport socket 
import select 
import sys 
if len( sys.argv ) !=4:print "Usage - ./banner_grab.py [Target.IP] [First Port] [Last Port]" 		print "Example - ./banner_grab.py 1.1.1.1 1 100" sys.exit()ip = sys.argv[1] 
start = int(sys.argv[2]) 
end = int(sys.argv[3]) 
for port in range(start,end):try: bangrab=socket.socket(socket.AF_INET,socket.SOCK_STREAM)bangrab.connect((ip,port))ready=select.select([bangrab],[],[],1) #连接间隔时间1秒 if ready[0]: print "TCP Port " + str(port) + "." +bangrab.recv(4096) bangrab.close() except: pass

结果如下:

root@root:~# chmod +x ./banner.py
root@root:~# ./banner.py 192.168.37.128 1 200

2.  服务扫描——服务识别

  • Banner信息抓取能力有限;
  • 需要借助于另类服务和识别方法进行进一步和准确性的判断;

(1)Nmap(开放端口对应的服务和版本)

3. 操作系统识别

  • 对操作系统的识别,可以判断出目标主机的操作系统类型,操作系统版本;
  • 针对不同的操作系统的版本,我们可以版本了解到系统默认会开放哪些服务;或者老版本操作系统自身的漏洞等;

(1)scapy(根据TTL值简单判断操作系统的类型)

root@root:~# scapy

使用脚本的方式:ttl_os.py

#!/usr/bin/python
#Author:橘子女侠
#该脚本用于通过TTL值的大小,简单的判断目标主机操作系统的类型
from scapy.all import *
import sys 
if len( sys.argv ) !=2:print "Usage - ./ttl_os.py [IP adress]" print "Example - ./ttl_os.py 1.1.1.1" sys.exit() ip = sys.argv[1] 
ans = sr1(IP(dst=str(ip))/ICMP(),timeout=1,verbose=0) 
if ans == None: print "No response was returned" 
elif int(ans[IP].ttl)<=64: print "Host is Linux/Unix" 
else: print "Host is Windows"
root@root:~# vim ttl_os.py
root@root:~# chmod +x ttl_os.py 
root@root:~# ./ttl_os.py 192.168.37.128

(4) 被动操作系统识别

  • 主动扫描:通过向目标系统发包,通过返回的信息,判断目标操操作系统的类型;
  • 被动扫描:不主动的向目标系统发包,基于一种网络抓包,监听的工作原理来进行识别目标操作系统;
