R Ransomware – How Is It Distributed

To be spread, the R Ransomware makes use of spamming software to send massive spam message campaigns to various e-mails all over the world. The messages may be of a deceitful origin, and they aim primarily to trick the victims using deceptive statements. The victims who are lured into opening malicious e-mail attachments or web links get their computers infected by an obfuscated loader which drops R Ransomware’s payload onto their computer.

Here are other ways by which the R Ransomware can be spread onto the computers of victims:

  • As a result of having a potentially unwanted program onto the user’s computer.
  • Via fake updates of programs.
  • Via fake installers uploaded on websites.
  • Via fake patches or game cracks uploaded in torrent sites.

R Ransomware – Infection Activity

After the R Ransomware causes an infection on the victim’s computer, the virus drops the payload. It might be located in the following Windows folders:

  • %AppDatA%
  • %Roaming%
  • %Local%
  • %LocalRow%
  • %SystemDrive%

The files may be from the following malicious file types:

→ .vbs, .dll, .tmp, .vbs, .bat, .exe

The names of those files may vary. They are usually completely random or imitate legitimate Windows processes. Once the virus has dropped them, R Ransomware may begin to modify the Windows Registry Editor of the infected computer. The modification is achieved by adding value strings and hence changing different settings. Usually, the following Windows registry sub-keys are targeted:

→ HKEY_CURRENT_USER\Control Panel\Desktop\
HKEY_USERS\.DEFAULT\Control Panel\Desktop\
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

Last but not least, R Ransomware may also delete the shadow copies from the machine which has been infected. These volume shadow copies can be eradicated by executing a script which quietly inserts and enters the following commands in Windows Command Prompt:

→ process call create “cmd.exe /c
vssadmin.exe delete shadows /all /quiet
bcdedit.exe /set {default} recoveryenabled no
bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures

R Ransomware’s Encryption Explained

For the encryption to work, the virus may cause the system to misbehave, so that the process is interrupted. Another scenario is if R Ransomware restarts the computer as an administrator and performs the encryption process on system boot. Whatever the case may be, the virus attacks different files that are widely used. Those particular types of files may be the following:

→ “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 .PRF Encoded Files .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 .OBJ R.BMP .DDS .GIF .JPG ..CRX .PLUGIN .FNT .FON .OTF .TTF .CAB .CPL .CUR .DESKTHEMEPACK .DLL .DMP .DRV .ICNS .ICO .LNK .SYS .CFG”Source:fileinfo.com

After the encryption is complete, the files seem damaged or corrupt and can no longer be opened. The R Ransomware infection then opens it’s ransom note which is named Ransomware.txt and looks like the following:
