What is Scarab Recovery ransomware? And how does it carry out its attack?
Scarab Recovery ransomware is a new file-encrypting threat that belongs to the infamous Scarab ransomware group. Just like the previous variants, this one still follows the same infection behavior tactics. It starts by employing an information gathering module once it infiltrates a computer. This module is used to scan the computer for signatures that belongs security programs as well as virtual machine hosts and sandbox/debug environments to make sure that none of them can interfere with the attack. It also modifies some Registry entries and sub-keys in the Windows Registry to allow it to run on every system boot. Following this modification, it looks for files with the following extensions to encrypt:
.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
After finding its targeted files, it will immediately encrypt them using a sophisticated cipher and appends the .Recovery extension right after. Following data encryption, it releases a text file named “HOW TO RECOVER FILES.txt” which contains the following content:
“=======================================================================
All your files are encrypted!!!!!!
=======================================================================
Your documents, photos, databases and other important data were encrypted.
Data recovery requires a decryptor.
To receive the decryptor, you should send an email to the email address:
[email protected] or
[email protected]
In the letter, indicate your personal identifier (see at the end of the document).
Then you will receive further instructions
Attention!
* Do not attempt to uninstall the program or run antivirus software
* Attempts to self-decrypt files will result in the loss of your data
