大家把实时监控查毒的东东暂时先禁止了,就可能正常运行了

我单位的机器安装的金山2007,运行提示驱动安装失败,我把监控关掉能进入了

可惜水平太菜,应该对付不了这个Cm

我们正在研究这个 crackme 不能运行的原因

有问题的朋友,请大家把 crackme 解压后,关掉防毒软件和所有调试器,使用 explorer 的直接方式,双按 crackme 打开,测试一下,确定是否真的不能加载

如果哪个共享软件的作者用这种方式让用户注册,会不会被用户群殴呀?算法在系统目录windows/system32/driver32下的驱动文件crackme02.sys中,只得用ring0的来调试了!

这个也不一定,riijj Crackme 12 也是类似这样的驱动加密,有的大牛改了PE的一些东东,就可以用OD调试了

(评审):

由于这个 crackme 的设计兼容性不足

根据比赛 crackme设计原则

「CrackMe 的设计可以应用于实际共享软件环境,并且有合理的运行时间,和容易注册的复杂度,并且有合理的系统兼容性和安全稳定」

判定这个crackme 不完善,扣去总分数的 1 / 3

维护其它参赛队伍的公平
