0x01 背景

前两周处理一个应急的时候发现的一个VipersoftX变种，并且整个分析过程还算闭环，所以记录下；

0x02 分析过程：

通过外联域名bideo-schnellvpn，初步判断是VenomSoftX窃密木马活动事件，并且受害机器在ids设备上触发了大量普通远控木马和窃密木马事件，大概率存在样本；

安装sysmon 收集日志；

通过sysmon日志找到外联进程及相关信息；

一、往后排查确认受影响相关：

定位进程参数：

拿到恶意脚本：

分析脚本，获取指定注册表键值执行：《HKEY_LOCAL_MACHINE\SOFTWARE\SolidWorks CorporationJQVQJ\c8dO7TYiv》

内容如下：

提取分析：

上述代码大致逻辑从 dns请求解析一个a.b.c域名的txt记录，a:(“endpoint”, “blog”, “chat”, “cdn”, “schnellvpn”),b:(“wmail”, “fairu”, “bideo”, “privatproxy”, “ahoravideo”),c:(“com”, “xyz”)

对获取的txt记录进行“解码” —>内置rsa公钥签名校验—>反射运行代码

如下是捕获的一次的txt记录：

参考捕获的第一txt记录，还原出来的二阶段代码逻辑：

获取相关环境变量和特定注册表值（计算机\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\MachineGuid），生成一个guid，访问http://xboxwindows.com/api/v1/$($guid)拉取样本：

简单分析相关代码逻辑：判断本地的app及其拓展安装情况，然后发回c2：

信息回传c2：http://xboxwindows.com/api/$guid

如下图回传c2相关信息：

如下图，该函数判断机器上相关指定目录下是否安装如下浏览器和相关拓展

寻找的相关路径：

其中涉及软件判断，kepass 和1password；（过去曾批漏，VenomSoftX窃密木马技战法中曾利用这两款软件的漏洞，这里应该也是一样的）

发现受害机器曾发起请求解析c2域名（xboxwindows.com）：

二、往前排查确认受感染由来

定位powershell进程由来，父进程 svchost：

父进程启动参数：-s Schedule ，如下图，应该是计划任务起来的：

排查计划任务：

发现恶意计划任务：

\Microsoft\Windows\Diagnosis\RecommendedTroubleshootingScannerbz4k3

触发器：

计划任务的由来：

查看本机计划任务创建相关日志windows安全日志（602，4698，4072）：

如下图：无果

上面我们发现计划任务中的恶意ps脚本创建时间是3月21日20:12分，排查盗版、破解、第三方软件安装记录：如下图，发现之前3月21日20：09曾下载一个xmind，和破解插件；

查找浏览器记录，发现下载地址：

找到下载链接：（www.1377x.to是一个提供盗版电影、电视剧、软件和其他数字内容的网站。）

https://www.1377x.to/torrent/5505841/XMind-2022-v22-11-2677-x64-Multilingual-crack-crackerfg/

推测大概率是利用破解为由混淆受害机器的使用人，一般都会觉得报毒是因为破解的原因，所以就会信任；

下载样本后：

四个文件：

分析：

《Xmind-for-Windows-x64bit-22.11.2677.exe》 hash:211199a054b1ebf6063a5b3f0cf1f80d 被官方签名的白安装程序

ErrorReport.dll和SCXTIPDILRQUR.exe均为木马；

三、奇怪的现象：

sysmon日志发现进程，发起恶意域名请求：

C:\Program Files (x86)\AlibabaProtect\1.0.70.1148\AlibabaProtect.exe

排文件和进程：

进程不存在dll劫持

文件均有签名

未发现异常，这里应该是阿里的沙箱之类的操作，尝试外联的；（如下图，这两年分析红队样本的时候，总是遇到下面这个arphaCrashReport.exe来做白加黑绕过终端防护设备，一直没找到出处，原来使阿里edr上的组件，这也算是解了我两年来的一个疑惑了，颇有他乡遇故知的意思~~）

0x03 总结

一、攻击链梳理

VipersoftX窃密木马伪装成Xmind破解插件置于www.1377x.to，诱使用户下载，运行后，释放运行恶意第一阶段ps脚本，并通过计划任务、注册表和文件实现持久化；第一阶段脚本会拉取特定路径缓存文件和特定路径注册表值作为代码执行；然后通过请求解析内置的一个list域名（(wmail|fairu|bideo|privatproxy|ahoravideo)-(endpoint|blog|chat|cdn|schnellvpn).(com|xyz)）的dns-txt记录，获取后的数据先使用内置的rsa公钥进行签名校验，接着解密拿到第二阶段的代码，并通过powershell反射调用执行；然后获取主机相关信息构造唯一id，带着唯一id回连c2：xboxwindows.com特定url，解密返回数据获取第三阶段代码，并执行；拉取受害机器的相关浏览器应用和插件安装情况以及密码管理软件等相关信息，带着这些信息回连c2：xboxwindows.com特定url，开展进一步的利用；

攻击链路图如下：

0x04 学习

通过此次分析，我们不难看出这种有一定规模的窃密组织，其整个杀伤链中还是做了很多对抗分析的和检测的手段；

1、payload加密混淆并隐藏到注册表键值中：通过注册表逃避edr的扫描和检测；

2、云端payload拉取采用dns隧道：通过txt记录传输加密payload，逃避ids流量监测；

3、对抗域名被接管情况：通过内置批量域名，并且对payload进行签名，客户端对签名进行校验，从而逃避被接管，对抗研究分析冉渊；

4、分阶段payload加载：通过多阶段从而拉长进程链，逃避edr检测；

5、payload反射加载：通过powershel独有的invoke反射加载，逃避edr检测；
