在不需要WiFi密码的情况下进行断网攻击

• 本教程只能用于学习研究之用 任何未经他人允许的攻击行为都是违法行为

• 参考教程 https://www.youtube.com/davidbombal

准备

* kali linux 系统  这里使用的是虚拟机 

* 一张可以开启监听模式的网卡
* 两张网卡使用那一张都可以

* 本教程使用的是 python编写的脚本代码 以下是部分代码
* 在代码中作者写了大量的注释 以供使用者参考

active_wireless_networks = []
# We use this function to test if the ESSID is already in the list file. 
# If so we return False so we don't add it again.
# If it is not in the lst we return True which will instruct the elif 
# statement to add it to the lst.
def check_for_essid(essid, lst):
    check_status = True

    # If no ESSIDs in list add the row
    if len(lst) == 0:
        return check_status
    # This will only run if there are wireless access points in the list.
    for item in lst:
        # If True don't add to list. False will add it to list
        if essid in item["ESSID"]:
            check_status = False

    return check_status
# Basic user interface header
# This is a period of output, don't want you to do it.

具体步骤

• 将提前准备好的 网卡插入 电脑并切换到虚拟机
• 由于kali linux 自带的python 不是3.7而是3.6 所以要重新下载 python
• 打开终端 输入一下命令 下载

wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz

• 解压压缩包

tar -zxvf Python-3.7.0.tgz
# 将解压出来的文件夹复制到 /usr/local/  目录下
cp -r python-3.7.0 /usr/local/

• 然后进行编译安装

./configure --enable-optimizations --prefix=/usr/local/Python-3.7/ && make && make install

• 在进入到解压出来的文件的位置后输入

./python --version

查看版本信息

• 在下载的python文件夹里 运行 python文件 s
• 上面的代码文件我已经放在了 ~/ 目录下

sudo ./python ~/wifi_dos_type1.py

• 这里会提示 插入的网卡 wlan0
• 因为这里只有一张 所以就只有一个 输入网卡前的序号
  
• 这里是自动开启网卡的监听模式 来扫描附近的WiFi
• 再按下 之后 会出现提示 在这里输入要攻击WiFi编号
  
• 输入编号之后 会自动攻击知道关掉终端或者 按 ctrl + c 强行中断
