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

ViiperWare ransomware is another malicious program designed to encrypt files and is coded using the open source platform – HiddenTear. According to researchers, this new ransomware seems to be an independent cyber threat which aims at targeting regular PC users. Infected users claimed that they got infected with this ransomware right after they opened an attachment they’ve downloaded from their emails which brings the conclusion that this malicious program spreads using malicious spam email campaigns. As soon as it gets a hold of the compromised computer, it immediately looks for the following file formats to encrypt:
.3gp, .7z, .apk, .avi, .bmp, .cdr, .cer, .chm, .conf, .css, .csv, .dat, .db, .dbf, .djvu, .dbx, .docm, ,doc, .epub, .docx .fb2, .flv, .gif, .gz, .iso .ibooks,.jpeg, .jpg, .key, .mdb .md2, .mdf, .mht, .mobi .mhtm, .mkv, .mov, .mp3, .mp4, .mpg .mpeg, .pict, .pdf, .pps, .pkg, .png, .ppt .pptx, .ppsx, .psd, .rar, .rtf, .scr, .swf, .sav, .tiff, .tif, .tbl, .torrent, .txt, .vsd, .wmv, .xls, .xlsx, .xps, .xml, .ckp, .zip, .java, .py, .asm, .c, .cpp, .cs, .js, .php, .dacpac, .rbw, .rb, .mrg, .dcx, .db3, .sql, .sqlite3, .sqlite, .sqlitedb, .psd, .psp, .pdb, .dxf, .dwg, .drw, .casb, .ccp, .cal, .cmx, .cr2.
During the encryption, the ransomware is said to be using an encryption method which is used for military-grade encryption. Meaning to say, it can be really hard to recover the encrypted files without a decryption key. It also appends the .viiper extension on each of them. After it is done with the encryption process, it displays a program window labeled “ViiperWare Ransomware” which offers a selection of different languages used for ransom notification. Aside from that, it also displays the following ransom message:
“1.) What Happened to my files?

  1. Your Files has been encrypted, what means you’re not able to use them anymore until you decrypt them.

2.) Can I recover my FIles?

  1. yes of course you can recover them. It’s pretty easy to do that but of course it is not free. Just Pay the Price wich is shown below and you will recive your Decryption Key after we received the Payment!

3.) How I got infected with this?

  1. Probably you tried to download something illegal from the Internet or you got scammed by someone.

[Enter Decryption|BUTTON] [Pay the Price|BUTTON] Price: 20,00 €”
No matter how hopeless you get, paying the ransom should not be a part of your options as these crooks can’t be trusted for they might only deceive you once they get what they want which is the money without giving you the decryption key. Your only saving grace for now would be backup copies of your files or at least try recovering them using their Shadow Volume Copies.
