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.

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"
