What is Docx ransomware? And how does it implement its attack?

Docx ransomware is a new file-encrypting threat that was found to be using the same distribution IP addresses as GandCrab ransomware. It was discovered by a malware security researcher named “S!Ri” and is designed to encrypt stored data in a computer leaving it inaccessible to victims.

Docx Ransomware
The instant it infects a system, it drops a malicious file which contains the following parameters:

SHA256:30ec73110c97a5ac5e923324b6874c41777a31b9b8a95467babcb9fb6bd3e982

Name:25d7ebac.gxe
Afterward, Docx ransomware makes changes in some critical Windows settings and system files such as:

  • advapi32.dll
  • comctl32.dll
  • gdi32.dll
  • kernel32.dll
  • oleaut32.dll
  • user32.dll
  • version.dll

The files listed above are modified in order to perform a lot of unauthorized procedure calls and actions. After that, it proceeds to employ a data gathering module used to gather information about the user and the system. The information obtained is used for another module called stealth protection used to keep any security programs and antivirus programs from interrupting the attack. The crypto-malware then proceeds to scan the computer for files with the following 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.

Once it finds its targeted files, Docx ransomware encrypts them using a sophisticated encryption algorithm and releases a file named “YOU_FILES_HERE.txt” that contains the following message:

“Your files are Encrypted!
For data recovery needs a decryptor.
How to buy a decryptor.
