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

SkyFile ransomware is a crypto virus detected at the beginning of April 2018. According to security experts, this crypto virus is filled with Russian debug logs and contains a command called “Attack” that exploits the EternalBlue. This kind of activity is not unheard of as it was also used by infamous ransomware threats like WannaCry ransomware before. Thankfully, SkyFile ransomware is not as dangerous as WannaCry ransomware as its code indicates that it is most likely developed by amateur cyber crooks. Even so, this ransomware shouldn’t be taken lightly as it can still leave your files inaccessible. It might target 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 finding files with the above mentioned extensions, SkyFile ransomware will start the encryption process using the AES cipher and append the .sky extension to the affected files. It then drops several malicious files such as the “SkyFile Decryptor.exe”, “skyfile.exe” and “HOW TO DECRYPT.txt”. The SkyFile Decryptor.exe, once clicked, will open a window that states:

“Oops, your files have been encrypted. Such as: photos, videos, documents, etc. To decrypt your files, read HOW TO DECRYPT.txt”

While the ransom note in the HOW TO DECRYPT.txt contains the following content:

“Oops, all your files have been encrypted =(

To decrypt your files, write to me at the e-mail: getsend@tutanota.com

Your data for decryption:

Private ID: ***

Private Key: *****”

As pointed out, there is no need for you to panic if you are one of the victims of this ransomware threat as it is not as dangerous as it seems and you can recover your encrypted files without having to spend a cent.
