【技术分享】Exchange渗透测试总结
本期安仔课堂，ISEC实验室的唐老师将为大家介绍Exchange相关知识点，欢迎感兴趣的
朋友一起交流学习。
一 、Exchange概述
Exchange是微软出品的邮件服务器系统，凭借其强大的功能优势被应用到很多企业、学校的
邮件系统搭建中。
截至目前，Exchange已有多个成熟版本，例如：Exchange Server 2010、2013、2016及最
新版本2019。此外，Exchange又可分为Exchange Server和Exchange Online ,为了方便，
本文将主要以本地Exchange Server 2010为例进行演示。

利用区块链技术隐藏C&C服务器IP

介绍
网络安全一直是猫捉老鼠的游戏。过去，我们看到恶意软件生态系统采用了诸如代码混淆，多态性，域
生成算法（DGA）以及虚拟机和沙箱规避等概念，只要防御能够对这些威胁进行一致且普遍的抑制。
一些攻击者最近开始使用比特币区块链来传达命令和控制（C＆C）信息。由于一旦矿工确认交... | pdf |

BeaconEye的原理
Cs的beacon在初始化时会使用 malloc 函数创建一个空间，将beacon的明文信息写入到其中。
这就是一个很明显的检测CobaltStrike的信息， malloc 函数创建的是堆内存，所以只需要遍历每个进程
的堆内存地址就可以了。
当然这一切都归功于很多前辈们对Cobalt Strike的逆向工程。
于是就有了beaconeye的项目https://github.com/CCob/BeaconEye
对于堆内存的查找还有很多注意事项，可以看参考中的文章。

问了下师傅，目标有个php dz的站有一个aspx的站，从aspx的读取文件读取到
web.config文件内容，是sa账号，但是降权了，而且传不到aspx文件网站目录里面，
只能传到dz的网站里面，一个asp冰蝎马。
用了师傅的网站看下进程(皮一下哈哈)
上次说过了，iis权限就算是管理员权限都一样，powershell啥的net net1肯定是没戏
的。你直接穿exe也是没戏的，连query user都看不了，也断掉了我们传exp上去提
权。
首先在aspx站找到了sa账号密码和dz的config目录里面找到了root账号i密码。
主要是有的马被杀了，而且由于我对sql server熟悉一点，所以直接执行。

尝试使⽤了这么久,使⽤这个插件挖到的漏洞也不少了,感觉是真实可⽤的
于是作为⼀个专业的狗推,我就要开始推荐AutoRepeater了
它作为⼀个burp⼯具,可以极⼤的简化⼿⼯测试的效率
