背景介绍
2021年3月2号,微软披露了Microsoft Exchange服务器的远程代码执行漏洞[1]。
2021年3月3号开始,360网络安全研究院Anglerfish蜜罐开始模拟和部署Microsoft Exchange蜜罐插件,很快我们搜集到大量的漏洞检测数据,目前我们已经检测到攻击者植入Webshell,获取邮箱信息,甚至进行XMRig恶意挖矿(http://178.62.226.184/run.ps1
)的网络攻击行为。根据挖矿文件路径名特征,我们将该Miner命名为Tripleone。
2021年3月6号开始,ProjectDiscovery和微软CSS-Exchange项目相继披露了漏洞检测脚本[2][3]。
Microsoft Exchange服务器的远程代码执行漏洞利用步骤复杂,一般从PoC公布到黑色产业攻击者利用需要一定的时间,我们看到这个攻击现象已经开始了。

Anglerfish蜜罐数据视野
2021年3月6日开始,360网络安全研究院Anglerfish蜜罐系统监测到Microsoft Exchange漏洞(CVE-2021-26855)扫描,截至日前,扫描源IP地址地理位置分布如下:
通过对扫描端口分析发现,扫描目的端口主要是443端口(77.3%),其次是80端口(11.3%),如下图:
根据分析捕获的扫描流量,扫描源IP ASN(Autonomous System Numbers)主要是Linode, LLC、DiGiTALOCEAN-ASN和LeaseWeb Netherlands B.V.,占比50%以上,扫描整体趋势如下:
对捕获的流量进行分析发现,Top 5的扫描IP占比所有扫描行为的50%,其中159.89.95.163占比达24%,暴露了该IP具有一定的组织性。
通过对攻击流量进行分析发现,攻击者已经能够成功利用该漏洞植入Webshell,详情如下图所示:
攻击者通过Webshell进一步实施恶意攻击操作,如植入XMRig挖矿程序,详情如下图所示:
部分扫描源IP rDNS SLD信息
我们通过简单分析Microsoft Exchange漏洞(CVE-2021-26855)扫描的扫描源IP对应的rDNS信息,可以看到一些组织信息。
Webshell 分析
我们监测到大量Webshell路径探测请求,其中大部分是安全厂商和研究机构的扫描行为。
