OVERVIEW
This Ransomware arrives on a system as a file dropped by other malware or as a file downloaded unknowingly by users when visiting malicious sites.
It drops files as ransom note.
TECHNICAL DETAILS
Arrival Details
This Ransomware 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 Ransomware drops the following files:
- %System Root%\qibfmqkeM5.log → contains list of files it was unable to encrypt
- %Temp%\M5-{10 random numbers}.dll → performs looking for target files
- %Temp%\M5-{10 random numbers}.dll → performs encryption of target files
(Note: %System Root% is the Windows root folder, where it usually is C:\ on all Windows operating system versions.. %Temp% is the Windows temporary folder, where it usually is C:\Windows\Temp on all Windows operating system versions.)
It adds the following processes:
- {Malware Directory}\{Malware File Name} +
- rundll32 %Temp%\M5-{10 random numbers}.dll,_run@16 {Drive Letter} → looks for files to encrypt
- rundll32 %Temp%\M5-{10 random numbers}.dll,_run@16 [1|2] → encrypts files
- vssadmin delete shadows /all /for={Drive Letter} → deletes volume shadow copies of affected drives
- vssadmin Resize ShadowStorage /MaxSize=320MB /for={Drive Letter} /on={Drive Letter} → resizes the maximum amount of storage space that can be used for shadow copy storage
- vssadmin Resize ShadowStorage /MaxSize=unbounded /for={Drive Letter} /on={Drive Letter} → resizes the maximum amount of storage space that can be used for shadow copy storage
- cipher /W:{Drive Letter} → wipes deleted files of affected drives
- wmic shadowcopy delete → deletes shadow copies
(Note: %Temp% is the Windows temporary folder, where it usually is C:\Windows\Temp on all Windows operating system versions.)
Other System Modifications
This Ransomware modifies the following registry entries:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows\CurrentVersion\Policies\
System
legalnoticecaption = "Locked By MegaCortex"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows\CurrentVersion\Policies\

Ransomware Routine
This Ransomware avoids encrypting files with the following strings in their file name:
- .blf
- .config
- .devicemetadata-ms
- .dll
- .exe
- .ico
- .lnk
- .manifest
- .mui
- .regtrans-ms
- .settingcontent-ms
- .sys
- .tlb
- .tmp
- .com
- bootmgr
- bootnxt
- desktop.ini
- iconcache.db
- ntuser.dat
- ntuser.dat.log1
- ntuser.dat.log2
- ntuser.ini
- usrclass.dat
- usrclass.dat.log1
- usrclass.dat.log2
It avoids encrypting files found in the following folders:
- %Windows%
(Note: %Windows% is the Windows folder, where it usually is C:\Windows on all Windows operating system versions.)
It appends the following extension to the file name of the encrypted files:
- .m3g4c0rtx
It drops the following file(s) as ransom note:
- %System Root%\!-!_README_!-!.rtf
SOLUTION
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
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
Restore these modified registry values
Important:Editing the Windows Registry incorrectly can lead to irreversible system malfunction. Please do this only if you know how to or you can seek your system administrator's help. You may also check out this Microsoft article first before modifying your computer's registry.
- In HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
- legalnoticecaption = Locked By MegaCortex
- In HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
- legalnoticetext = Contact: Victoriareimann@mail.com or Casiuslerman@mail.com
Step 4
Search and delete this file
- %System Root%\qibfmqkeM5.log
- %Temp%\M5-{10 random numbers}.dll
- %Temp%\M5-{10 random numbers}.dll
- %System Root%\!-!_README_!-!.rtf
Step 5
Scan your computer with your Trend Micro product to delete files detected as Ransom.Win32.MEGACORTEX.THKOFAI. 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 6
Enabling Volume Shadow Service
- Run the command prompt (cmd.exe) as administrator.
- Enable Volume Shadow Service by typing the following command:
net start vss
Step 7
Restore encrypted files from backup.
NOTES:
Enabling Disabled Service
- Run the command prompt (cmd.exe) as administrator
- Enable disabled service using the following command: sc config {service name} start
