.betta Dharma Virus - How Does It Infect

.betta Dharma Virus – How Does It Infect

Various methods in relation to Dharma ransomware virus have been detected so far. One of them is to spread the virus via spammed e-mail messages. Such e-mails may pretend to be various legitimate types of files:

  • Invoices.
  • Receipt.
  • Important banking document.
  • Password change notification.
  • Other important files.

These e-mails may be created in a very cunning way, for example, they may imitate e-mails that may be coming from legitimate types of organizations, like:

  • eBay.
  • PayPal.
  • Dropbox.
  • Banks and companies.

The primary malicious file that has been detected(https://www.virustotal.com/#/file/1b1fdf8bc5d2d39ac6e90aba18b44f6cc4fe26c93bcf09ce1d98793b1c1f132f/behavior) in association with Dharma ransomware to be with the following indicators of compromise:

→ SHA-256: 1b1fdf8bc5d2d39ac6e90aba18b44f6cc4fe26c93bcf09ce1d98793b1c1f132f
Size: 624 KB

Besides via e-mail, the infection may also be spread as a result of being uploaded on various suspicious sites in the form of a malicious JavaScript web link and redirect. This is very typical for compromised sites that cause numerous redirections or for adware programs that may have affected your computer.

If spread by a file, that is uploaded online, the malicious infection module of Dharma may pose as some sort of a game patch, software activator, crack, key generator, portable program and other forms of seemingly useful programs.


Dharma .betta Virus - Activity

Dharma .betta Virus – Activity

Once installed on the victim’s computer, the Dharma ransomware’s .betta variant may act in very close way to the other variants of Dharma, belonging to the .cezar family. So far, we have been covering Dharma ransomware for quite some time now and there have been a lot of iterations of the virus with new one being released each week:

After an infection with Dharma’s .betta variant takes place, the malware may drop it’s payload in the following Windows Directories:

  • %AppData%
  • %Local%
  • %Roaming%
  • %LocalLow%
  • %Temp%

The files that are dropped may have different file names and these names are often random ones.

Once the virus has dropped it’s main payload, it begins it’s malicious activities. For starters, Dharma ransomware opens and interacts with the following Windows files to likely obtain administrator rights:

→ C:\WINDOWS\system32\winime32.dll
C:\WINDOWS\system32\ws2_32.dll
C:\WINDOWS\system32\ws2help.dll
C:\WINDOWS\system32\psapi.dll
C:\WINDOWS\system32\imm32.dll
C:\WINDOWS\system32\lpk.dll
C:\WINDOWS\system32\usp10.dll
C:\WINDOWS\system32\comctl32.dll
C:\WINDOWS\system32\shell32.dll
C:\WINDOWS\WinSxS\x86_Microsoft.Windows.Common-Controls_6595b64144ccf1df_6.0.2600.5512_x-ww_35d4ce83\comctl32.dll
C:\WINDOWS\WindowsShell.Manifest
C:\WINDOWS\system32\MSCTF.dll
C:\WINDOWS\system32\MSCTFIME.IME

Once this is done, the .betta Dharma ransomware may also open and modify the following Windows Registry sub-keys:

→ \Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\996E.exe
\Registry\MACHINE\System\CurrentControlSet\Control\SafeBoot\Option
\Registry\Machine\Software\Policies\Microsoft\Windows\Safer\CodeIdentifiers
\REGISTRY\MACHINE\SOFTWARE\Policies\Microsoft\Windows\Safer\CodeIdentifiers\TransparentEnabled
\REGISTRY\USER\S-1-5-21-1482476501-1645522239-1417001333-500\Software\Policies\Microsoft\Windows\Safer\CodeIdentifiers
\Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\ole32.dll
\Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\oleaut32.dll
\Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\version.dll
\Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\comctl32.dll
\Registry\Machine\Software\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\SHELL32.dll

But Dharma ransomware does not stop there. The ransomware is also clever enough to open the ShimCacheMutex and also create the following mutexes:

→CTF.LBES.MutexDefaultS-1-5-21-1482476501-1645522239-1417001333-500
CTF.Compart.MutexDefaultS-1-5-21-1482476501-1645522239-1417001333-500

CTF.TMD.MutexDefaultS-1-5-21-1482476501-1645522239-1417001333-500
CTF.TimListCache.FMPDefaultS-1-5-21-1482476501-1645522239-1417001333-500MUTEX.DefaultS-1-5-21-1482476501-1645522239-1417001333-500

When done, the Dharma ransom virus also loads the following Runtime modules:

→ imm32.dll
Cmctl32.dll
C:\WINDOWS\system32\MSCTF.dll
C:\WINDOWS\system32\ msctfime.ime
C:\WINDOWS\system32 \ole32.dll

Among the files dropped by Dharma ransomware’s .betta virus variant is the malware’s ransom note file, which looks like the following:


Dharma .betta Ransomware - Encryption

Dharma .betta Ransomware – Encryption

Just like other Dharma variants, this version for the virus also skips encrypting files in important Windows directories, like:

  • %System%
  • %Local%
  • %Temp%
  • %Windows%
  • %System32%
  • %Program Files%

To encrypt the files, the .betta version of Dharma ransomware first scans for the files it aims to encrypt. The virus looks for often used files and targets them based on their file extensions:

“PNG .PSD .PSPIMAGE .TGA .THM .TIF .TIFF .YUV .AI .EPS .PS .SVG .INDD .PCT .PDF .XLR .XLS .XLSX .ACCDB .DB .DBF .MDB .PDB .SQL .APK .APP .BAT .CGI .COM .EXE .GADGET .JAR .PIF .WSF .DEM .GAM .NES .ROM .SAV CAD Files .DWG .DXF GIS Files .GPX .KML .KMZ .ASP .ASPX .CER .CFM .CSR .CSS .HTM .HTML .JS .JSP .PHP .RSS .XHTML. DOC .DOCX .LOG .MSG .ODT .PAGES .RTF .TEX .TXT .WPD .WPS .CSV .DAT .GED .KEY .KEYCHAIN .PPS .PPT .PPTX ..INI .PRFEncodedFiles .HQX .MIM .UUE .7Z .CBR .DEB .GZ .PKG .RAR .RPM .SITX .TAR.GZ .ZIP .ZIPX .BIN .CUE .DMG .ISO .MDF .TOAST .VCD SDF .TAR .TAX2014 .TAX2015 .VCF .XML Audio Files .AIF .IFF .M3U .M4A .MID .MP3 .MPA .WAV .WMA Video Files .3G2 .3GP .ASF .AVI .FLV .M4V .MOV .MP4 .MPG .RM .SRT .SWF .VOB .WMV 3D .3DM .3DS .MAX .OBJR.BMP .DDS .GIF .JPG ..CRX .PLUGIN .FNT .FON .OTF .TTF .CAB .CPL .CUR .DESKTHEMEPACK .DLL .DMP .DRV .ICNS .ICO .LNK .SYS .CFG”

Once Dharma ransomware has detected the files it wants to encrypt, the virus then applies the Advanced Encryption Standard cipher, also known as AES encryption. This cipher generates a unique asymmetric encryption key, the outcome of which is that the file can no longer be opened. After encryption, Dharma ransomware leaves the files looking like the following image:
