The WantMoney Ransomware is an encryption ransomware Trojan that was observed on December 4, 2017. The WantMoney Ransomware may be delivered to victims through the use of spam email messages, which are posed as legitimate messages from well-known companies such as Facebook, Amazon or PayPal. These email messages will contain a corrupted file attachment in the form of a Microsoft Word document with bad macro scripts that download and install the WantMoney Ransomware onto the victim's machine. The WantMoney Ransomware's purpose is to infect the victims' computers and encrypt the victim's data with a strong encryption algorithm. This makes the files inaccessible, enabling the WantMoney Ransomware to demand a ransom payment in exchange for the decryption key that the victims will need to get back their files.

When Someone Wants Other People's Money

The WantMoney Ransomware will use a combination of AES and RSA encryption to make the victim's files completely inaccessible by its attack, making it impossible with current technology to restore files if one does not have the decryption key. The WantMoney Ransomware targets the user-generated files, which may include media files and a wide variety of document formats. The file types of files that attacks like the WantMoney Ransomware will target in their attacks include:

.3dm, .3g2, .3gp, .7zip, .aaf, .accdb, .aep, .aepx, .aet, .ai, .aif, .as, .as3, .asf, .asp, .asx, .avi, .bmp, .c, .class, .cpp, .cs, .csv, .dat, .db, .dbf, .doc, .docb, .docm, .docx, .dot, .dotm, .dotx, .dwg, .dxf, .efx, .eps, .fla, .flv, .gif, .h, .idml, .iff, .indb, .indd, .indl, .indt, .inx, .jar, .java, .jpeg, .jpg, .js, .m3u, .m3u8, .m4u, .max, .mdb, .mid, .mkv, .mov, .mp3, .mp4, .mpa, .mpeg, .mpg, .msg, .pdb, .pdf, .php, .plb, .pmd, .png, .pot, .potm, .potx, .ppam, .ppj, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .prel, .prproj, .ps, .psd, .py, .ra, .rar, .raw, .rb, .rtf, .sdf, .sdf, .ses, .sldm, .sldx, .sql, .svg, .swf, .tif, .txt, .vcf, .vob, .wav, .wma, .wmv, .wpd, .wps, .xla, .xlam, .xll, .xlm, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml, .xqx, .xqx, .zip.

The WantMoney Ransomware will rename the files it encrypts, following the pattern below:

[5 random chars]-[5 random chars]-[5 random chars]-[5 random chars].Encrypted[B32588601@163.com].WantMoney2

This makes it uncomplicated to know which files have been encrypted by the WantMoney Ransomware attack.

The WantMoney Ransomware's Ransom Demand

The WantMoney Ransomware will demand a ransom payment, asking victims to communicate with its perpetrators via the email address 'B32588601@163.com' and pay a ransom of 0.1 Bitcoin, nearly 1,000 USD at the current exchange rate. The WantMoney Ransomware delivers its ransom note in the form of a text file named '_Want Money_.txt' that is dropped on the infected computer's desktop. The WantMoney Ransomware also will replace the infected computer's desktop image with the file '_Want Money_.bmp.' Apart from these two, the WantMoney Ransomware also will create a program window named 'Want Money Ransomware.' The WantMoney Ransomware's ransom notes all contain the following message for the victim:
