.Cezar Ransomware Virus – How Did I Get It?

The Dharma ransomware and the .cezar strain are distributed across the web via different methods. One of the most popular is spam email messages. They can be one of the following types:

  • Spam messages with malicious attachments – These types of email messages are sent in bulk to the targets and they include infected binaries as file attachments. Various social engineering tricks are used to make the computer users download and open the file. The files may pose as financial documents, important messages or other types of data that may be of interest.
  • Spam messages with malicious links – They are similar to the above-mentioned messages however they feature links to various hacked and malicious sites that host the binaries instead of offering them as attachments. This is done to prevent the automatic virus scanners from discarding the message.
  • Spam messages that deliver both malicious links and attachments – A widely used strategy by computer criminals.

Other infection methods include exploit kits, browser hijackers, Trojans and other types of hacking attacks.

.Cezar Ransomware virus – How Does It Work?

The .cezar ransomware virus will be dropped into your computer, after which the virus will attempt to get itself deep into the operating folders. The usual folders are:

    %AppData%
    %Temp%
    %Roaming%
    %System32%
    %Common%

The dropped files will try to mask themselves as other system files. The OS is full of such little files, so it may be hard to locate them if you’re trying to remove the virus. This is why manual removal can be tricky, if not outright dangerous for your system.

The virus will try to target some of the following file types:

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

The .cezar Dharma ransomware aims to find all target files mentioned above so it can implement the AES encipher algorithm and render them completely unusable. This latest variant of Dharma is associated primarily with the .cezar file extension and an email address that is left by the hackers as a way to contact them for the payment process.

During the encryption process, the ransomware generates a decryption key, connects to its remote command and control server and delivers the key to the crooks. The whole infection process happens unnoticeably until its final stage. During its last stage, the ransomware drops an HTA, TXT, JPG or HTML file that contains a ransom message and payment instructions. The file is likely to be located on the desktop as well as in all folders that contain encrypted files. The .cezar ransomware virus may also modify the default desktop wallpaper and replace it with the ransom note. As the previous .wallet and .onion variants, .cezar Dharma ransom message instructs victims how to contact hackers at a given email in order to follow their further instructions and transfer Bitcoins to a given bitcoin address.

The Dharma .cezar file virus is also likely to change and create objects in the Windows Registry editor. Modifications of Run and RunOnce registry keys allow the threat to run automatically its malicious files on each Windows startup. The syntax of some the affected registry keys is:

  • 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
