大佬们，求个aspx免杀大马和思路
现在情况是遇见一个.net4.0的站，传了免杀的哥斯拉冰蝎马，连接不上，马没有被杀；
怀疑有流量设备，所以想传个大马，网上找了很多大马，要么被杀，要么报错；
报错信息如下，因为我菜鸡不懂代码，所以希望有师傅可以分析一下情况或者给个好马子；
师傅还可以简单讲讲出现这种情况的原因的话那最好不过了

已经解决问题了各位师傅们，非常感谢；两种解决方案：1）用天蝎直接连2）把域名换成ip和端口号再连接虽然到现在不知道问题的成因是什么，但起码有了临时解决方案；欢迎各位师傅做出简单分析和解释；
IP能直接连上 是不是域名有做CDN加速被CDN的WAF拦截
又学到一个姿势，竟然可以使用ashx后缀
应该是waf，不像是杀毒

用IP和端口就能链接，那说明有waf吧

虽然也没有连接成功，但谢谢师傅给的马， 问题已经有了解决的方案，谢谢师傅参与的讨论

先随便写个123，也报错就是配置问题，估计只支持asp
传个txt 里面写上shell代码 看看是不是基于文件内容做的查杀。具体是不是过滤了哪些函数。
你先弄个正常的aspx试试能不能运行，要是也不能运行很可能配置有问题，不是马的事了
运行错误不代表不能执行，只要不是抛出具体错误代码就行

菜刀直接连
多换不同个版本的连接工具试试
先写个123 在aspx看显示啥
一般是版本问题，但是里面的杀软不清楚，有的时候defender杀shell挺狠，可以找几个加密的大马，适用性也强，小马几乎被秒杀
传个asmx试试，基本不会被拦
也试过，连不上
用最早的那个菜刀试试
一般aspx报错也是可以连接的，用蚁剑试试，aspx马找不到asp的也可以试试，或者aspx图片大马
这我知道，哥斯拉冰鞋都试过了
