关于Il2cpp的资料网上有很多,简而言之,Il2cpp就是unity用来代替原来的基于Mono虚拟机的一种新的打包方式,它先生成IL(中间语言),然后再转换成Cpp文件,提高运行效率的同时增加了安全性。原本基于Mono的打包方式极其容易被逆向,现在市面上的新游戏基本上都是用Il2cpp的方式打包的,当然Il2cpp的逆向教程也很多,但...
从il2cpp的API出发，利用Class::GetFieldFromName和相关函数解析字段信息。通过递归初始化类和父类的FieldInfo，找到MetadataCache::GetFieldOffsetFromIndexLocked函数，这个函数可以帮助获取到字段的偏移地址。总结：Il2Cpp恢复符号的过程是一个复杂但有序的过程，它涉及到对globalmetadata.dat文件的解析、对il2...
