关于小程序login的code问题About the code problem of applet login

Framework type problem type API / component name terminal type wechat version basic library version applet bug Wx Login() wechat Android client unknown 1.0.0 https://developers.weixin.qq.com/miniprogram/dev/framework/open-ability/login.html According to the document, the applet needs to call Wx After login, get the code, and then the code can be exchanged for the user. Openid code can only be used once. But recently, it was found that the attacker generated user information by triggering our backend to detect the interface of code and passing in the code. Question: 1 Where did he get his code? Why did he have a large number of codes (I found that the code he requested can create about 500 users every day)? 2. Does wechat have other registration methods besides avoiding registration through IP or other technical means?
