抓不到的包? SSL Pinning 的锅~!....

简单的 HTTPS 抓包都会用, 就不说了, 无论 Fiddler 还是 Charles 都很简单, 关于部分抓不到的, 是因为代码中开启了 SSL Pinning

• 针对于 iOS 开发来说, 这篇文章关于 AF 设置 SSL Pinning, 个人没有经历过这种开发, 不是很了解, 取证困难, 使用简单哈哈哈哈哈

• 想要抓取 SSL Pinning 的包, 需要手机越狱, 越狱后在 Cydia 中添加以下插件

  • Debian Packager
  • Cydia Substrate
  • PreferenceLoader
  

• 安装完成后去 GitHub 下载 ssl-kill-switch2 , 下载最新的就好, 已经支持 iOS10 以上, 然后将该文件拷贝到 iOS 设备中
  

  

• ssh 连接设备后执行如下命令进行安装

dpkg -i com.nablac0d3.sslkillswitch2_0.12.deb
killall -HUP SpringBoard

安装结果

至此, 就可以去抓包了, 我用的是饿了么练手的
至于想要是用非越狱的就抓包, 需要对想要抓包的 APP 进行逆向, 解包, HOOK 设置 SSL Pinning 的相关代码, 关键词是 trust, 犹豫比较困难不做介绍了哈哈哈
