某平台作弊检测方法&bypass思路

AmIzero

在分析某平台检测作弊玩家方式时，发现此平台思路与众不同，将反作弊的方法与地图联系在一起。
该地图内嵌lua脚本，似乎使用了 https://github.com/actboy168/YDWE 这个项目制作

解包地图后发现大量无规律编号的lua脚本
根据“作弊”关键字定位到有关的lua脚本 __f0361__.lua

全图的检测
function __0x2597__ 根据检测是设置的标志 计算玩家为作弊玩家的置信值
function __0x2604__ 在置信度高于99的时候 有（20%）的几率设置作弊玩家的标志位 这主要是为了迷惑作弊玩家
function __0x2618__ 准备一个单位列表 然后通过LUA引擎调用JASS函数尝试选择单位 如果不可见的单位被选中 或者 可见的单位没有被选中 则 与作弊有关的标志被更新
有关的标志 __0x2589__  __0x2591__ __0x2590__ __0x2592__ __0x2593__
如果未检测到作弊 只有 __0x2590__  被设置

查看敌方技能 、技能cd的检测
标志位 __0x2594__ 通过LUA引擎获取玩家能观察到的单位技能 如果玩家能查看到敌对单位的技能则更新 __0x2594__

反检测的思路 检测时JASS函数selectunit会被平台调用，因此只要在selectunit的入口进行处理

检查堆栈中的返回地址
如果是来自Game.DLL的调用 则什么都不做
如果不是可以有多种操作方式 比较简单的就是暂时关闭作弊 经过一段延时后再开启作弊
反技能检测
直接patch GetPlayerAlliance 即可

能否告知是哪张地图？（地图名）

其实 已经相当明显了

主要是有没有写出来软件是最重要的

這個防作弊方法果然是思路清奇啊。。。
