W32.Rarogminer – How Does It Spread
The main methods used to propagate the W32.Rarogminer on the computers of victims are self-replicating, meaning that the malware is spread from an infected computer to another infected computer through removable drives.
The procedure via which this is done is when the worm has already infected a computer, it begins to drop copies of itself on flash drives. The copies have the following names:
- Autorun.inf
- Autorun.exe
And the worm does not perform this action once, but regularly each time you insert a flash drive, external HDD or any other external memory carrier. When the infected removable drive is connected to a clean device, the worm starts it’s infection activity.
W32. Rarogminer Worm (lsass.exe) – Technical Analysis
When the W32.Rarogminer worm infects a given computer, the malware may start to drop it’s payload. It may be dropped on the victim’s computer as a result of creating files with configurations based on scripts that extract them or as a result of downloading those files by connecting to the cyber-criminals’ distribution site. Either way, as Symantec researchers report, the Rarogminer worm drops the following files into important Windows Directories:
→ MicrosoftCorporation\Windows\Helpers\SecurityHeaIthService.exe
MicrosoftCorporation\Windows\Helpers\SystemldleProcess.exe
MicrosoftCorporation\Windows\Helpers\winIogon.exe
MicrosoftCorporation\Windows\System32\Isass.exe
\WindowsAppCertification\WindowHelperStorageHostSystemThread.ps1
WindowsAppCertification\cert.cmd
WindowsAppCertification\checker.vbs
{random}\driver.dat
%System%\Tasks\Windows_Antimalware_Host
%System%\Tasks\Windows_Antimalware_Host_Systm
%SystemDrive%\ProgramData\MicrosoftCorporation\Windows\Helpers\SecurityHeaIthService.exe
%SystemDrive%\ProgramData\MicrosoftCorporation\Windows\Helpers\SystemldleProcess.exe
%SystemDrive%\ProgramData\MicrosoftCorporation\Windows\Helpers\winIogon.exe
%SystemDrive%\ProgramData\MicrosoftCorporation\Windows\System32\Isass.exe
%SystemDrive%\ProgramData\WindowsAppCertification\WindowHelperStorageHostSystemThread.ps1
%SystemDrive%\ProgramData\WindowsAppCertification\cert.cmd
%SystemDrive%\ProgramData\WindowsAppCertification\checker.vbs
%SystemDrive%\ProgramData\{random}\driver.dat
%UserProfile%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\Isass.lnk
The main one of those malicious files has been reported to be lsass.exe which is responsible for the mining activities off the W32.Rarogminer. The virus creates a registry entry for the malicious file so that it starts automatically with Windows:
→ HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\”Windows_Antimalware_Host_Syst” = %ProgramData%\MicrosoftCorporation\Windows\System32\Isass.exe
The worm then begins checking if the below-mentioned processes are running on the compromised computer:
→ cryptonight
dwarfpool
minergate
monerohash
nanopool
nicehash
stratum
suprnova
xmrpool
If those processes are running, the worm deletes itself. And the worm can also stop itself to start again during the time the following processes are not running:
→ AnVir
KillProcess
NetMonitor
Process Hacke
Process Killer
System Explorer
Taskmgr.exe
If detected, the worm temporarily closes until the next time it’s ran on Windows boot.
The main purpose of the W32.Rarogminer worm is to perform mining operations on the computer of the victim. However, the worm is one of the more sophisticated threats, meaning that it can perform a variety of activities on the infected machine, including:
- Download files and start them.
- Open web links on your browser.
- Perform DDoS attacks to targeted networks or PCs.
- Create copies of itself.
- Shut itself down and delete itself.
- Start itself once it has shut down.
- Perform self-update operations to keep it’s malicious files hidden.
To conduct the mining operation, the worm uses a file, called xmrig32.exe. This file is downloaded by connecting to the following remove host:
→ 107.181.160.63/xmrig32.exe
The worm downloads the file in a randomly named folder within %Program Data%.
Then, the worm infection may connect to a lot of API (access point interface) type of hosts that are likely mining pools for cryptocurrencies or related to crypto. The websites, reported by the researchers are as follows:

From there, the malware may begin to perform the so-called hashing operation, which results in cryptocurrency tokens from the Monero cryptocurrency being generated. As the number of infected computers rises, the faster it becomes to generate tokens. The tokens are then sent to the wallets of the cyber-criminals, making them richer and richer at the expense of the victim’s CPU and GPU resources. And not only this, but if it remains for longer periods of time on your computer, slowing down of it’s performance may be your least important problem. The virus may have an actual capability of breaking down your computer’s components as a result of overheating them.

You can access them by opening the Windows registry editor and deleting any values, created by W32.Rarogminer there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.Step 3: Find virus files created by W32.Rarogminer on your PC.
1.For Windows 8, 8.1 and 10.
For Newer Windows Operating Systems
1: On your keyboard press + R and write explorer.exe in the Run text box and then click on the Ok button.
2: Click on your PC from the quick access bar. This is usually an icon with a monitor and its name is either “My Computer”, “My PC” or “This PC” or whatever you have named it.
3: Navigate to the search box in the top-right of your PC's screen and type “fileextension:” and after which type the file extension. If you are looking for malicious executables, an example may be "fileextension:exe". After doing that, leave a space and type the file name you believe the malware has created. Here is how it may appear if your file has been found:
N.B. We recommend to wait for the green loading bar in the navigation box to fill up in case the PC is looking for the file and hasn't found it yet.
2.For Windows XP, Vista, and 7.
For Older Windows Operating Systems
In older Windows OS's the conventional approach should be the effective one:
1: Click on the Start Menu icon (usually on your bottom-left) and then choose the Search preference.
2: After the search window appears, choose More Advanced Options from the search assistant box. Another way is by clicking on All Files and Folders.
3: After that type the name of the file you are looking for and click on the Search button. This might take some time after which results will appear. If you have found the malicious file, you may copy or open its location by right-clicking on it.
Now you should be able to discover any file on Windows as long as it is on your hard drive and is not concealed via special software.
