免杀能力强突破、代理功能替代vshell、全界面汉化 | GoCobaltStrike 2.3发布!
文章看起来感觉挺牛逼对吧，还有web界面。gui界面，免杀能力还提升了就这玩意据说1千多人花了218进他的星球就为了吃这一坨大的。
第一眼看着文章很多人都蠢蠢欲动了吧，结果花了钱进去过后，整个c2的特征估计都被标记烂了不说，自己说的免杀能力强突破结果一言难尽（我自己哪怕用vshell写个c的loder编译出来12kb的exe加上bin文件执行都能静态动态过卡巴的，怎么你这还需要自己重新写个loder吗？很多人不都是奔着免杀效果来的，你这强突破，我是真没看出来哪里突破了）更神奇的是你上线也有问题，而且对cna脚本不太适配，我的妈耶，就这玩意218啊，我把这218拿去买token是不是自己也能搓一个出来了
真的说不下去了，我的评价是：不如vshell，光是我一个人吃了难受，这样可不行，这就放出来给各位品鉴一下咸淡！
