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

JSWorm ransomware is a file-encrypting virus designed to lock important files in a computer and demand ransom from victims in exchange for file recovery. This new crypto-malware was discovered in the second half of January 2019 and uses the .JSWORM extension to mark the files it encrypts.

The instant its payload file is dropped in the system, JSWorm will establish a connection to a remote Command and Control server where it downloads its other components and places them on several system folders. These components are then used to execute two modules that will be used for the attack. The first module known as data gathering is the one that collects information from the system. The data obtained is then used for the second module known as stealth protection, combined with the collected data and some components; it is the one that scans the system for strings of any sandbox environment, security and antivirus programs that might interfere with the attack. Afterwards, it modifies some registry keys and sub-keys in the Windows Registry, allowing it to automatically run in every system boot. After all these modifications, JSWorm ransomware will scan the system in search 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 .DOC .SEON .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 it finds its targeted files, JSWorm will encrypt them using the AES cipher and append the .JSWORM extension, signifying that the files are encrypted. Following data encryption, it opens an html file named “JSWORM-DECRYPT.html” which contains the following message:

ALL YOUR FILES LOCKED!
