现在OD加上StrongOD也会被Nk查到。。。。本人逆向小白,所以找不到更多的了。也许让我老老实实写写代码或许好得多:)

算法应该不会修改的,毕竟是外包产品,服务器与客户端同时升级的成本,比少数人使用路由器的损失多得多了。听说电信买这个软件花了百万的价钱,O(∩_∩)O~ 。我逆向主要是针对Mac与Android版,Windows我也不太擅长。

按我个人推测来说的话服务器端应该是有一个Radius列表来控制账号计算的PIN码校对。我以前还觉得如果电信同时计算两个和以上radius的话对服务器负载是不是有点大,现在看来我被打脸了。按照过去的推测PIN码有效期前后10M左右应该都是OK的。如果电信只是改RADIUS的话那么问题就比较简单了,但是这么一来的话因为RADIUS改变所以对应PIN码列表也会变更,可能电信可以借此查出版本然后强制心跳也不好说。心跳服务器只是加一台的问题,毕竟这东西需要的资源也就摆在那里。
另外我逆向了下安卓的APP,心跳部分可能还是有问题,电脑客户端应该是AES之类的,但是很奇怪不知道是我抓的包有问题还是代码有问题,AES和3DES始终是没法解密心跳包的数据。KEY应该是没问题的。比较奇怪的是上次模拟心跳发送电信也没有返回UDP包,看了94版本找到的东西估计是只对强制新版本的学校开心跳验证了吧。
不过电信这个时候换radius也真是吓了我一跳。。。。

现在的情况是能找到心跳的关键call,但是看不懂汇编,也不知道是怎么走的,94版查逆向似乎有手段了一样。。。也许我得多试试:)

已经确定只是修改了radius。

我的学校貌似还能用呢,那么这个新的radisu,我这个op项目,还有你那个Android版个APP也需要更新了吗?

现在是两个radius都能用。不管是之前的cqxinliradius002还是现在的xianxinli1radius,现在是并存的,等哪天强制更新94版本的时候估计就是必须更新的时候了

好吧,那我也把它加上去了

:) 心跳包依然没进展,有一个字段我始终找不到怎么算的。醉了醉了。。。。。
