Arrival Details

This Backdoor 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 Backdoor adds the following processes:

  • "powershell" Get-MpPreference -verbose
  • schtasks.exe /Create /TN "Updates\VrajlR" /XML "%User Temp%\tmpEC7F.tmp"
  • %Windows%\Microsoft.NET\Framework\v2.0.50727\vbc.exe "{path}"
  • %System%\DllHost.exe /Processid:{AB8902B4-09CA-4BB6-B78D-A8F59079A8D5}
  • %System%\svchost.exe -k LocalServiceAndNoImpersonation
  • %System%\svchost.exe -k LocalServiceNetworkRestricted
  • "%System Root%\Program Files\Windows Media Player\wmpnetwk.exe"

(Note: %User Temp% is the current user's Temp folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Temp on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Local\Temp on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).. %Windows% is the Windows folder, where it usually is C:\Windows on all Windows operating system versions.. %System% is the Windows system folder, where it usually is C:\Windows\System32 on all Windows operating system versions.. %System Root% is the Windows root folder, where it usually is C:\ on all Windows operating system versions.)

It creates the following folders:

  • %AppDataLocal%\Microsoft\Windows\Explorer
  • %Windows%\ServiceProfiles\LocalService\AppData\Roaming\Microsoft\UPnP Device Host\upnphost
  • %Windows%\ServiceProfiles\LocalService\AppData\Roaming\Microsoft\UPnP Device Host
  • %Windows%\ServiceProfiles\LocalService\AppData\Roaming\Microsoft

(Note: %AppDataLocal% is the Local Application Data folder, which is usually C:\Documents and Settings\{user name}\Local Settings\Application Data on Windows 2000(32-bit), XP, and Server 2003(32-bit), or C:\Users\{user name}\AppData\Local on Windows Vista, 7, 8, 8.1, 2008(64-bit), 2012(64-bit) and 10(64-bit).. %Windows% is the Windows folder, where it usually is C:\Windows on all Windows operating system versions.)

Other System Modifications

This Backdoor deletes the following files:

  • %Windows%\ServiceProfiles\LocalService\AppData\Local\lastalive1.dat
  • %Windows%\ServiceProfiles\LocalService\AppData\Local\lastalive0.dat

(Note: %Windows% is the Windows folder, where it usually is C:\Windows on all Windows operating system versions.)

  SOLUTION

Minimum Scan Engine:

9.850

Step 1

Before doing any scans, Windows 7, Windows 8, Windows 8.1, and Windows 10 users must disable System Restore to allow full scanning of their computers.

Step 2

Identify and terminate files detected as Backdoor.MSIL.REMCOS.APG

[ Learn More ]
  1. Windows Task Manager may not display all running processes. In this case, please use a third-party process viewer, preferably Process Explorer, to terminate the malware/grayware/spyware file. You may download the said tool here.
  2. If the detected file is displayed in either Windows Task Manager or Process Explorer but you cannot delete it, restart your computer in safe mode. To do this, refer to this link for the complete steps.
  3. If the detected file is not displayed in either Windows Task Manager or Process Explorer, continue doing the next steps.

Step 3

Delete this registry value

Step 6

Scan your computer with your Trend Micro product to delete files detected as Backdoor.MSIL.REMCOS.APG. If the detected files have already been cleaned, deleted, or quarantined by your Trend Micro product, no further step is required. You may opt to simply delete the quarantined files. Please check the following Trend Micro Support pages for more information:

Step 7

Restore this file from backup only Microsoft-related files will be restored. If this malware/grayware also deleted files related to programs that are not from Microsoft, please reinstall those programs on you computer again.

  • %Windows%\ServiceProfiles\LocalService\AppData\Local\lastalive1.dat
  • %Windows%\ServiceProfiles\LocalService\AppData\Local\lastalive0.dat

Step 8

Restore these deleted registry keys/values from backup

*Note: Only Microsoft-related keys/values will be restored. If the malware/grayware also deleted registry keys/values related to programs that are not from Microsoft, please reinstall those programs on your computer.
