C:\Users\user\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\5zy4hsui.lnk

In addition to this, the Saturn ransomware virus also begins to delete the shadow volume copies and disable system recovery from the victim’s comptuer by executing a script in Windows Command Prompt which runs the following commands as an administrator:

→ process call create “cmd.exe /c vssadmin.exe delete shadows /all /quiet & bcdedit.exe /set {default} recoveryenabled no & bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures”

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

After the files are encrypted by this virus, they will receive a file extension .saturn and become no longer able to be opened. This is because they are believed to be encoded via the RSA (Rivest-Shamir-Adleman) encryption algorithm. This procedure is done with several different type of encryption modes, generating unique decryption keys for each file. The files may appear like the following after being encrypted by Saturn Ransomware:
