<p>通过分析物联网设备遭受攻击的链条可以发现，黑客获取固件，把固件逆向成汇编或C程序语言后，能分析出设备的运行流程和网络行为，还能找到安全加密相关的密钥相关的信息。如果这些“有心人”没能获取到固件信息，他们也很难发现这些漏洞。从这一点看，物联网设备的安全性，在很大程度上决定于其固件的安全性。</p>

|
||
<p>还好华为路由器自带了抓包的功能（方便后期的调试和维护），所以直接使用这个功能抓取报文，比做中间人要直接了当得多。</p>
|
||
<p>在点击升级固件之后，我们可以看到大量发往58.49.156.104这个地址的报文，猜测极有可能是华为的服务器，过滤一下会看得更清楚<br><img src="https://res.cloudinary.com/dozyfkbg3/image/upload/v1563606353/samples/1.png" alt><br>可以看到在通过三次TCP握手之后，华为路由器向服务器发送了get请求，uri就是获取固件的地址 <a href="http://update.hicloud.com/TDS/data/files/p14/s145/G4404/g1810/v272964/f1/WS5200_10.0.2.7_main.bin" target="_blank" rel="noopener">http://update.hicloud.com/TDS/data/files/p14/s145/G4404/g1810/v272964/f1/WS5200_10.0.2.7_main.bin</a><br>点击即可拿到最新的固件</p>
