The encryption process of Saturn ransomware is conducted by the virus targeting often used files, such as music, videos, images and other often used files for encryption and then performing the encryption process. The files which are targeted may contain the following file extension:

.1c, .3fr, .accdb, .ai, .arw, .bac, .bay, .bmp, .cdr, .cer, .cfg, .config, .cr2, .crt, .crw, .css, .csv, .db, .dbf, .dcr, .der, .dng, .doc, .docm, .docx, .dwg, .dxf, .dxg, .eps, .erf, .gif, .htm, .html, .indd, .iso, .jpe, .jpeg, .jpg, .kdc, .lnk, .mdb, .mdf, .mef, .mk, .mp3, .mp4, .mrw, .nef, .nrw, .odb, .ode, .odm, .odp, .ods, .odt, .orf, .p12, .p7b, .p7c, .pdd, .pdf, .pef, .pem, .pfx, .php, .png, .ppt, .pptm, .pptx, .psd, .pst, .ptx, .r3d, .rar, .raw, .rtf, .rw2, .rwl, .sql, .sr2, .srf, .srw, .tif, .wb2, .wma, .wpd, .wps, .x3f, .xlk, .xls, .xlsb, .xlsm, .xlsx, .zip
