反抓包及解决方案
vpn检测与证书校验区别
- vpn检测 在抓包软件看不到请求，请求发不出去，已经被扼杀在摇篮里了
-
证书校验 在抓包软件里会看到请求，但通常都会提示证书校验不通过
解决SSLPining问题
-
可以替换app中的https请求为http，然后http的请求就解决了证书校验的问题
-
之后在charles map remote中建立映射规则，在中间人这把http映射为https,这样既能抓到包。服务器还不会轻易知道
在charles中找到
这样设置
对抗抓包解决方案
vpn检测
采用hook_vpn.js
sslpining client校验server
client校验server
DroidSSLUnpining.js
multi_unpinning.js
just_trust_me.js
server校验client
tracer-keystore.js
keystore_dump.js
r0capture.js
网络框架
未混淆okhttp
hook_okhttp3.js
遇到的情况少
混淆okhttp
just_trust_me_okhttp_hook_finder.js
OkHttpLogger-Frida
hook系统底层
hook_all.js
