After this, the ransomware may begin to scan for and encrypt the user’s files. A malware researcher, named Demonslay335 at BleepingComputer forums has reported that Surprise ransomware scans for and encrypts the following file extensions:
→ “.asf”, “.pdf”, “.xls”, “.docx”, “.xlsx”, “.mp3”, “.waw”, “.jpg”, “.jpeg”, “.txt”, “.rtf”, “.doc”, “.rar”, “.zip”, “.psd”, “.tif”, “.wma”, “.gif”, “.bmp”, “.ppt”, “.pptx”, “.docm”, “.xlsm”, “.pps”, “.ppsx”, “.ppd”, “.eps”, “.png”, “.ace”, “.djvu”, “.tar”, “.cdr”, “.max”, “.wmv”, “.avi”, “.wav”, “.mp4”, “.pdd”, “.php”, “.aac”, “.ac3”, “.amf”, “.amr”, “.dwg”, “.dxf”, “.accdb”, “.mod”, “.tax2013”, “.tax2014”, “.oga”, “.ogg”, “.pbf”, “.ra”, “.raw”, “.saf”, “.val”, “.wave”, “.wow”, “.wpk”, “.3g2”, “.3gp”, “.3gp2”, “.3mm”, “.amx”, “.avs”, “.bik”, “.dir”, “.divx”, “.dvx”, “.evo”, “.flv”, “.qtq”, “.tch”, “.rts”, “.rum”, “.rv”, “.scn”, “.srt”, “.stx”, “.svi”, “.swf”, “.trp”, “.vdo”, “.wm”, “.wmd”, “.wmmp”, “.wmx”, “.wvx”, “.xvid”, “.3d”, “.3d4”, “.3df8”, “.pbs”, “.adi”, “.ais”, “.amu”, “.arr”, “.bmc”, “.bmf”, “.cag”, “.cam”, “.dng”, “.ink”, “.jif”, “.jiff”, “.jpc”, “.jpf”, “.jpw”, “.mag”, “.mic”, “.mip”, “.msp”, “.nav”, “.ncd”, “.odc”, “.odi”, “.opf”, “.qif”, “.xwd”, “.abw”, “.act”, “.adt”, “.aim”, “.ans”, “.asc”, “.ase”, “.bdp”, “.bdr”, “.bib”, “.boc”, “.crd”, “.diz”, “.dot”, “.dotm”, “.dotx”, “.dvi”, “.dxe”, “.mlx”, “.err”, “.euc”, “.faq”, “.fdr”, “.fds”, “.gthr”, “.idx”, “.kwd”, “.lp2”, “.ltr”, “.man”, “.mbox”, “.msg”, “.nfo”, “.now”, “.odm”, “.oft”, “.pwi”, “.rng”, “.rtx”, “.run”, “.ssa”, “.text”, “.unx”, “.wbk”, “.wsh”, “.7z”, “.arc”, “.ari”, “.arj”, “.car”, “.cbr”, “.cbz”, “.gz”, “.gzig”, “.jgz”, “.pak”, “.pcv”, “.puz”, “.rev”, “.sdn”, “.sen”, “.sfs”, “.sfx”, “.sh”, “.shar”, “.shr”, “.sqx”, “.tbz2”, “.tg”, “.tlz”, “.vsi”, “.wad”, “.war”, “.xpi”, “.z02”, “.z04”, “.zap”, “.zipx”, “.zoo”, “.ipa”, “.isu”, “.jar”, “.js”, “.udf”, “.adr”, “.ap”, “.aro”, “.asa”, “.ascx”, “.ashx”, “.asmx”, “.asp”, “.indd”, “.asr”, “.qbb”, “.bml”, “.cer”, “.cms”, “.crt”, “.dap”, “.htm”, “.moz”, “.svr”, “.url”, “.wdgt”, “.abk”, “.bic”, “.big”, “.blp”, “.bsp”, “.cgf”, “.chk”, “.col”, “.cty”, “.dem”, “.elf”, “.ff”, “.gam”, “.grf”, “.h3m”, “.h4r”, “.iwd”, “.ldb”, “.lgp”, “.lvl”, “.map”, “.md3”, “.mdl”, “.nds”, “.pbp”, “.ppf”, “.pwf”, “.pxp”, “.sad”, “.sav”, “.scm”, “.scx”, “.sdt”, “.spr”, “.sud”, “.uax”, “.umx”, “.unr”, “.uop”, “.usa”, “.usx”, “.ut2”, “.ut3”, “.utc”, “.utx”, “.uvx”, “.uxx”, “.vmf”, “.vtf”, “.w3g”, “.w3x”, “.wtd”, “.wtf”, “.ccd”, “.cd”, “.cso”, “.disk”, “.dmg”, “.dvd”, “.fcd”, “.flp”, “.img”, “.isz”, “.mdf”, “.mds”, “.nrg”, “.nri”, “.vcd”, “.vhd”, “.snp”, “.bkf”, “.ade”, “.adpb”, “.dic”, “.cch”, “.ctt”, “.dal”, “.ddc”, “.ddcx”, “.dex”, “.dif”, “.dii”, “.itdb”, “.itl”, “.kmz”, “.lcd”, “.lcf”, “.mbx”, “.mdn”, “.odf”, “.odp”, “.ods”, “.pab”, “.pkb”, “.pkh”, “.pot”, “.potx”, “.pptm”, “.psa”, “.qdf”, “.qel”, “.rgn”, “.rrt”, “.rsw”, “.rte”, “.sdb”, “.sdc”, “.sds”, “.sql”, “.stt”, “.tcx”, “.thmx”, “.txd”, “.txf”, “.upoi”, “.vmt”, “.wks”, “.wmdb”, “.xl”, “.xlc”, “.xlr”, “.xlsb”, “.xltx”, “.ltm”, “.xlwx”, “.mcd”, “.cap”, “.cc”, “.cod”, “.cp”, “.cpp”, “.cs”, “.csi”, “.dcp”, “.dcu”, “.dev”, “.dob”, “.dox”, “.dpk”, “.dpl”, “.dpr”, “.dsk”, “.dsp”, “.eql”, “.ex”, “.f90”, “.fla”, “.for”, “.fpp”, “.jav”, “.java”, “.lbi”, “.owl”, “.pl”, “.plc”, “.pli”, “.pm”, “.res”, “.rsrc”, “.so”, “.swd”, “.tpu”, “.tpx”, “.tu”, “.tur”, “.vc”, “.yab”, “.aip”, “.amxx”, “.ape”, “.api”, “.mxp”, “.oxt”, “.qpx”, “.qtr”, “.xla”, “.xlam”, “.xll”, “.xlv”, “.xpt”, “.cfg”, “.cwf”, “.dbb”, “.slt”, “.bp2”, “.bp3”, “.bpl”, “.clr”, “.dbx”, “.jc”, “.potm”, “.ppsm”, “.prc”, “.prt”, “.shw”, “.std”, “.ver”, “.wpl”, “.xlm”, “.yps”, “.1cd”, “.bck”, “.html”, “.bak”, “.odt”, “.pst”, “.log”, “.mpg”, “.mpeg”, “.odb”, “.wps”, “.xlk”, “.mdb”, “.dxg”, “.wpd”, “.wb2”, “.dbf”, “.ai”, “.3fr”, “.arw”, “.srf”, “.sr2”, “.bay”, “.crw”, “.cr2”, “.dcr”, “.kdc”, “.erf”, “.mef”, “.mrw”, “.nef”, “.nrw”, “.orf”, “.raf”, “.rwl”, “.rw2”, “.r3d”, “.ptx”, “.pef”, “.srw”, “.x3f”, “.der”, “.pem”, “.pfx”, “.p12”, “.p7b”, “.p7c”, “.jfif”, “.exif”, “.rar”

The files are encrypted with two types of encryption algorithms to make the decryption even more impossible than it currently is – RSA-2048 and AES-256. Both of the algorithms are very difficult to decrypt because they are military-grade. After encryption, Surprise ransomware sets the .suprise file extension on the user PC, for example:
- Picture.jpg becomes Picture.jpg.surprise
Upon opening the encrypted files, the user may either encounter a message saying the file cannot be opened or the following Windows suggestion pop-up:
After encryption, the ransomware drops two notepad files that are called:
- DECRYPTION_HOWTO.Notepad
- Encrypted_Files.Notepad
These are the reported contents of the “DECRYPTION_HOWTO.Notepad” file:
→ What happened to your files ?

As a bottom line, the ransomware can set up to 25 bitcoins for the user’s data which is approximately 10000 US dollars. It is advisable not to pay the ransom money due to several different reasons:
- You fund the cybercriminals to spread and develop this malware.
