Rijndael Ransomware – Remove It and Restore .fucked Files

This article will aid you in removing the Rijndael ransomware in full. Follow the ransomware removal instructions given at the bottom of the article.

The Rijndael ransomware has been discovered by the malware researcher Michael Gillespie. The ransomware will not only encrypt your files, but also lock your Desktop screen. Believed to be developed by a hacker group called “Deathnote Hackers”. When a computer gets infected, the Rijndael cryptovirus will display a window with a ransom message. That message shows right after the file-encryption process is completed.

Rijndael Ransomware – Infection Spread

Rijndael ransomware might spread its infection through different ways. The payload file which executes the malicious script for this ransomware, that in turn infects your computer system, is circling around the Internet. Samples of this ransomware have been found by a few different malware researchers. You can see the detections of various security vendors for one such sample by checking the screenshot from the VirusTotal service right here:

Rijndael ransomware could also spread its payload file on social media sites and file-sharing networks. Freeware applications which are found on the Web could be presented as helpful but at the same time could be hiding the malicious script for this cryptovirus. Don’t be opening files right when you have downloaded them, especially if they come from sources such as suspicious links or emails. Instead, you should scan them beforehand with a security tool, while also checking the sizes and signatures of those files for anything that seems unusual. You should give the tips for ransomware prevention a read, found on our forum section.

Rijndael Ransomware – Detailed Overview

Rijndael is a ransomware cryptovirus which is based on the .killedXXX File Virus (DNransomware). Once your files get encrypted by this latest variant, they will receive the .fucked extension.

The Rijndael ransomware could make entries in the Windows Registry aiming to achieve a higher level of persistence and to keep the lockscreen function on top of all other windows. Those registry entries are typically designed in a way that will start the virus automatically with each launch of the Windows Operating System.

The ransom message will pop up after the encryption process is finished. That message contains instructions on how you might get your files back. The note of Rijndael opens in a window, which also activates the lockscreen feature. You can see the message from that note in the snapshot provided down here:

The ransom message inside that window reads the following:

Your Computer files is encrypted all files is encrypted with extremely powerfull new RIDNDAEL encryption that no one can break except you have a private string and IVs
To Decrypt Your File You Should Pay Me 0.5 BTC (864.98 USD)
Contact Me : [email protected]
insert your code here:

As clearly seen from the ransom message above, the developer of the Rijndael cryptovirus wants 0.5 Bitcoin as payment. At the time of writing of this article, that amount is equivalent to 571 US dollars. If you get your computer infected with the malware, you should NOT under any circumstances pay any sum of money to the crooks that are behind it. Nobody can guarantee that you will get your files restored upon payment. Besides, you should read about the unlock code, found by researcher Michael Gillespie, a little further down this article.

Rijndael Ransomware – Encryption Process

Rijndael ransomware will most likely follow its past variants and encrypt files that have the following extensions:

→.png, .psd, .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, .dwg, .dxf, .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, .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, .aif, .iff, .m3u, .m4a, .mid, .mp3, .mpa, .wav, .wma, .3g2, .3gp, .asf, .avi, .flv, .m4v, .mov, .mp4, .mpg, .rm, .srt, .swf, .vob, .wmv, .3d, .3dm, .3ds, .max, .obj, .bmp, .dds, .gif, .jpg, .crx, .plugin, .fnt, .fon, .otf, .ttf, .cab, .cpl, .cur, .deskthemepack, .dll, .dmp, .drv, .icns, .ico, .lnk, .sys, .cfg

The encryption algorithm is claimed to be AES, by the ransomware developers.

If you want to remove the lock on your screen and decrypt your files, all you have to do is type in the following unlock code:

83KYG9NW-3K39V-2T3HJ-93F3Q-GT

Be aware that a defense mechanism might be in place, that could break your files if the wrong unlock code is entered, as it was the case with the Noob Ransomware virus. Also, there might be a case when entering the code might not decrypt your files, although there is no such case registered yet.

The Rijndael cryptovirus could be set to erase the Shadow Volume Copies from the Windows Operating System with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

The execution of that command usually makes the encryption more viable, since it eliminates one of the prominent ways for the restoration of your data.
