小程序逆向 #
-
抓包
电脑版微信最新版抓不了包，用3.7.6一下的
微信在登陆时，右上角把代理填上
把AppData\Roaming\Tencent\WeChat\XPlugin\Plugins里面的东西删了，不影响使用
-
解密
下载aen516954023/wxappUnpacker: 微信小程序本地应用包逆向工具 (github.com)
解密wxapkg文件，在C:\Users\xxx\Documents\WeChat Files\Applet
在解密的时候出现各种几把问题，均可参考百度，google等
可能因为解密不出来wml和wss不能动态调试很难受
wxapkg文件解包
其他的单独解
-
逆向
因为没有拿到wml和wss，所以只能静态分析
还好比较简单
因为不能调试，不知道最后一个sign传的什么参数，是做的md5
