[分享]hook抓包的风控解决方案

抓包应该是我们逆向的第一步，只有先抓到包，才能决定我们是否要进行脱壳、逆向。万一他没有加密、万一数据不是我们想要的那岂不是白忙活了。但是目前很APP都设置了门槛，比如新版的抖音、淘宝、天眼查等挂上代理就直接无数据或者就显示不出你想要的数据。还没有开始就直接结束了，让人懊恼不已。没办法只能上科技与狠活了。（感谢r0ysue肉师傅，以下很多素材都来源于他）
这个一般我们设置好IP和端口，导入证书不出意外是没问题。常见的抓包工具fiddler、charles、Burpsuite、httpcanary
针对双向证书绑定的APP，打印和保存证书，再导入到抓包工具中。
将证书导出后，charles进行证书配置。
ssl pinning 证书在代码中的额外校验：
objection 中的 Bypass SSL pinning hook的证书种类：
DroidSSLUnpinning 这个工具是WooyunDota瘦蛟舞大佬总结的，github上有源码，以下我也贴出来了，他总结了一些常见的证书过检测的方法。
使用方法：
1 attach : frida -U com.example.mennomorsink.webviewtest2 --no-pause -l hooks.js
2 spawn : frida -U -f com.example.mennomorsink.webviewtest2 -l hooks.js --no-pause
如果APP出现了混淆，使用 objection、DroidSSLUnpinning都无法成功hook住，首先不要慌，我们的目标还是先搞清楚他用的是什么框架。可以hook java.io.File类，因为校验证书的过程中，必然要打开它，通过打印的调栈再结合源码可以分析出到底使用了什么框架。
r0capture安卓应用层抓包通杀脚本这个工具比较厉害，无视所有证书校验或绑定，不用考虑任何证书的事情。
Spawn 模式：
python3 r0capture.py -U -f com.coolapk.market -v
Attach 模式，抓包内容保存成pcap文件供后续分析：
python3 r0capture.py -U 酷安 -v -p iqiyi.pcap

你好博主，我有一个APP也很苦恼，抓不到，有偿能帮我分析下吗？预算1000元
企鹅：876529930 样品下载地址：https://game.xiaomi.com 就是这个游戏中心APP。

dy也是双向证书绑定，他在so文件里面做了校验，要修改后再重新打包，即可 |
|
|
你要抓小米的干啥 |
|
|
|
|
|
应用程序在进行SSL/TLS通信时启用了双端证书验证，将会拒绝与Charles之类的中间人进行通信,攻击者需要欺骗应用程序接受伪造证书，这通常需要在应用程序或操作系统中添加根证书或信任受信任的根证书颁发机构（CA），可以将APP本地的校验的证书，导入到Charles，只要行为一致，则可以进行通信。 |
|
|
|
|
|
你说的是，服务端对客户端的证书验证，你是通过将客户端的证书导入到chales, 客户端对服务端的证书验证，是通过注入客户端，修改他的认证部分代码是吗 |
