What is XeroWare ransomware? And how does it execute its attack?

XeroWare ransomware also called XeroWare ransomware 1.2.1, is a data-locking malware created based on the infamous open-source platform, HiddenTear. Like other HiddenTeae variants, it is designed to encrypt files in an infected computer in exchange for a ransom.

Once it manages to infiltrate a computer, it begins to execute its attack by dropping its malicious payload in the system. It may be placed on the following Windows directories:

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

After dropping its malicious payload, it connects the infected machine to a remote server controlled by the attackers. From there, it downloads several malicious files used for its attack. These files may be placed on system folders just like the malicious payload and will be used to make sure that no program installed in the computer can interfere with its attack. It also makes modifications in some of the registry values and sub-keys to allow it to automatically run on every system boot. After these changes, it scans the entire drive of 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. 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 it finds these files, it may use the AES cipher in locking them. Once the encryption is completed, it appends the .XERO extension to each one of the encrypted files and releases a ransom note with a message that reads:

“Your files have been encrypted and your computer has been infected with XeroWare Ransom 1.2. 1) What Should I do?

A: Pay the specific amount we are asking from you in order to decrypt your files.

2) Can I try to remove the malware?
