A crypto-virus, mocking Windows 10 OS has been released and is reported be a variant of the Troldesh(Shade) ransomware variants. The .windows10 file extension is added to every file which is encoded with a strong encryption algorithm. The virus also leaves a ransom note in which it demands from its victims to contact the e-mail Ryabinina.Lina@gmail.com for further information. This is done most likely to get a feel for the victim while negotiating and make him/her pay money in the form of BitCoins to get access back to the encrypted files.

Windows 10 Ransomware and Its Spread
The creators of the Windows 10 ransomware have most likely used massive spam campaigns to deliver it throughout different computers around the globe. The spammed messages may have different content, for example:
- “Your PayPal Receipt”
- “Confirmation Bank Statement”
- “Your Deadline Expires Tomorrow”
- “Credit Card Details”
- “Thank You For Your Purchase!”
This technique is known as social engineering and aims to get users to open the spammed e-mail message. If the user opens it, there can be found a malicious web link in the e-mail’s body which may redirect and infect the user via Exploit Kit. Another threat which may be discovered is malicious e-mail attachments which can infect the user by using malicious macros and JavaScript code.
Windows 10 Ransomware In Depth
As soon as its activated on the computer it has infected, Windows 10 ransomware may connect to the cyber-criminals’ command and control server which is masked using Tor networking. From there, the Windows 10 virus may choose a key from the server it has connected to and encrypt the files of the infected machine.
Similar to Shade ransomware, Windows 10 virus may look for the following types of files which it scrambles with a strong encryption:
→ Wb2, cdr, srw, p7b, odm, mdf, p7c, 3fr, der, odb, arw, rwl, cer, xlk, pdd, rw2, crt, dx, r3d, pem, bay, ptx, pfx, mdb, rtf, txt, xml, csv, pdf, prn, dif, slk, ods, xltx, xlm, odc, xlw, uxdc, pm, udl, dsn, iqy, dqy, oqy, cub, bak, frm, opt, myd, myi, db, onetoc2, one, onepkg, vcs, ics, pst, oft, msg, pptx, ppt, pptm, pps, ppsm, pot, potx, ptm, dwg, dxf, docx, doc, docm, dct, mef, cin, sdpx, dpx, fido, dae, dcm, dc3, dic, eps, kmz, iff, html, mht, mhtml, shtml, hta, htc, ssi, as, asr, xsl, xsd, dtd, xslt, rss, rdf, lbi, asa, ascx, asmx, config, cfm,cfml, cfc, tld, phtml, jsp, svg, svgz, rle, tga, cda, icb, wbm, wbmp, jpf, jpx, jp2, j2k, j2c, jpc, avi, mkv, movm, mp4, wmv, 3gp, mpg, mpeg, m4v, 7z, rar, tar, gz, bz2, wim, xz, c, h ,hpp, cpp, php, php3, php4, php5, py, pl, sln, js, json, inc, sql, java, class, ini Source: TrendMicro
The encryption algorithm which is believed to be used by Windows 10 ransomware is RSA cipher which is [very strong in bits. The ransomware also, adds the .windows 10 file extension and is believed to scramble the names of the encrypted files, for example:
→ Original file:
New Text Document.txt
Encrypted File
12dh2380d23248f397800x98dbx9g823f834fb3.{VICTIM-ID here}.windows10
The victim’s ID is added as a sub-extension between the scrambled name and the original name of the ransomware and it is also alpha numerical with capitalized letters, for example:
→ A784D238R3093C
After the damage is done, Windows 10 ransowmare changes the background of the infected computer to an image, looking the same as Shade Ransomware(see the picture at the beginning of this article). It also drops a README.txt file with numbers, for example README1.txt, README2.txt and so on. The text file has ransom instructions on how to contact the cyber-criminals in an anonymous manner:
→ “All the important files on your computer were encrypted.
To decrypt the files you should send the following code:
{UNIQUE ID HERE}
to e-mail address Ryabinina.Lina@gmail.com .
Then you will receive all necessary instructions.
All the attempts of decryption by yourself will result only in irrevocable loss of your data.
If you still want to try to decrypt them by yourself please make a backup at first because
the decryption will become impossible in case of any changes inside the files.
If you did not receive the answer from the aforecited email for more than 48 hours (and only in this case!),
use the feedback form. You can do it by two ways:
1) Download Tor Browser from here:
