Zenis Ransomware Removal – Restore Zenis- Files

This article will aid you to remove Zenis ransomware efficiently. Follow the ransomware removal instructions provided at the end of the article.

Zenis is a virus that encrypts your files and demands money as a ransom to get your files restored. According to some malware researchers, all files of a compromised computer get locked with the AES military grade encryption algorithm. The Zenis cryptovirus will encrypt your data and files, while also prepending the Zenis- prefix in front of file names and an extension to each file. The extension varies between infected machines, but a base64 code is used for its generation. Continue to read the article and see how you could try to potentially recover some of your files.

Zenis Ransomware – Ways of Distribution

Zenis ransomware might spread its infection in various ways. A payload dropper which initiates the malicious script for this ransomware is being spread around the World Wide Web, and researchers have gotten their hands on a malware sample. If that file lands on your computer system and you somehow execute it – your computer system will become infected.

Zenis ransomware might also distribute its payload file on social media and file-sharing services. Freeware which is found on the Web can be presented as helpful also be hiding the malicious script for the cryptovirus. Refrain from opening files right after you have downloaded them. You should first scan them with a security tool, while also checking their size and signatures for anything that seems out of the ordinary. You should read the tips for preventing ransomware located at the corresponding forum thread.

Zenis Ransomware – In-Depth Description

Zenis is a virus that encrypts your files and places an .html file, with instructions inside the infected computer system. The extortionists want you to pay a ransom fee for the alleged restoration of your files. The ransom fee may vary according to the victims. A couple of companies have already claimed to be hit with this ransomware and is possible that they will be charged more for the alleged recovery of their files.

Zenis ransomware could make entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows environment. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows operating system.

After encryption the Zenis virus shows a ransom message located inside a file called “Zenis-Instructions.html”. You can see its contents from the following screenshot given down here:

The ransom note states the following:

*** All your files has been encrypted ***
I am ZENIS. A mischievous boy who loves cryptography, hardware and programming. My world is full of unanswered questions and puzzles half and half, and I’m coming to discover a new world.
A world in digital space that you are supposed to play the role of my toys.
If you want to win in this game, you have to listen carefully to my instructions, otherwise you will be caught up in a one-step game and you will become the mam loser of the story.
My instructions are simple and clear. Then follow these steps:
1. Send this file (Zenis-Instructions.html) to my email with one your encrypted file less than 2 MB to trust to the game.
2. I decrypt your file for free and send for you.
3. If you confirm the correctness of the files, verify that the files are correct via email
4. Then receive the price of decrypting files
5. After you have deposited, please send me the payment details
6. After i confirm deposit, i send you the “Zenis Decryptor” along with “Private Key” to recovery all your files.
Now you can finish the game. You won the game. congratulations.

Please submit your request to both emails:
TheZenis@Tutanota.com
TheZems@MailFence.com
If you did not receive an email after six hours, submit your request to the following emails:
TheZenis@Protonmail.com
TheZenis@Mail2Tor.com (On the TOR network)

Warning: 3rd party and public programs. It may cause irreversible damage to your files. And your files will be lost forever.

As it becomes evident from the ransomware note, the following e-mail addresses are given as a way to contacting the cybercriminals:

  • TheZenis@Tutanota.com
  • TheZems@MailFence.com
  • TheZenis@Protonmail.com
  • TheZenis@Mail2Tor.com

The note of the Zenis ransomware states that your files are encrypted. You are demanded to pay an unknown sum of money. The prices between a single computer and multiple, as well as a single person/home and a company may vary. However, you should NOT under any circumstances pay any ransom sum. Your files may not get recovered, and nobody could give you a guarantee for that. Adding to that, giving money to cybercriminals will most likely motivate them to create more ransomware viruses or commit different criminal activities. That may even result to you getting your files encrypted once again.

Zenis Ransomware – Encryption Process

What is known for the encryption process of the Zenis ransomware is that every file that gets encrypted will receive the Zenis- prefix. The prefix will be prepended to the name of an encrypted file, and after the dash, two symbols will be added. In addition, there will be a base64 extension appended to each file, meaning 12 more symbols will be placed as an extension. Base64 includes all letters from the Latin alphabet and the 0-9 digits.

That randomization of the extension and prefix of files might make it harder for malware researchers to come up with a decryptor. However, if a real decryption application exists, there is hope that a free decryption tool could be made available.

The full list with the targeted extensions of files which are sought to get encrypted is shown right down here:

→.3fr, .7z, .accdb, .ai, .apk, .arch00, .arw, .asp, .aspx, .asset, .avi, .bar, .bay, .bc6, .bc7, .big, .bik, .bkf, .bkp, .blob, .bsa, .cas, .cdr, .cer, .cfr, .cr2, .crt, .crw, .css, .csv, .d3dbsp, .das, .dazip, .db0, .dba, .dbf, .dcr, .der, .desc, .dmp, .dng, .doc, .docm, .docx, .dwg, .dxg, .epk, .eps, .erf, .esm, .ff, .flv, .forge, .fos, .fpk, .fsh, .gdb, .gho, .hkdb, .hkx, .hplg, .html, .hvpl, .ibank, .icxs, .indd, .itdb, .itl, .itm, .iwd, .iwi, .jpe, .jpeg, .jpg, .js, .kdb, .kdc, .kf, .layout, .lbf, .litemod, .lrf, .ltx, .lvl, .m2, .m3u, .m4a, .map, .mcmeta, .mdb, .mdb, .mdbackup, .mddata, .mdf, .mef, .menu, .mlx, .mov, .mp4, .mpqge, .mrwref, .ncf, .nrw, .ntl, .odb, .odc, .odm, .odp, .ods, .odt, .orf, .p12, .p7b, .p7c, .pak, .pdd, .pdf, .pef, .pem, .pfx, .php, .pk7, .pkpass, .png, .ppt, .pptm, .pptx, .psd, .psk, .pst, .ptx, .py, .qdf, .qic, .r3d, .raf, .rar, .raw, .rb, .re4, .rgss3a, .rim, .rofl, .rtf, .rw2, .rwl, .sav, .sb, .sid, .sidd, .sidn, .sie, .sis, .slm, .sln, .snx, .sql, .sql, .sr2, .srf, .srw, .sum, .svg, .syncdb, .t12, .t13, .tax, .tor, .txt, .upk, .vcf, .vdf, .vfs0, .vpk, .vpp_pc, .vtf, .w3x, .wb2, .wma, .wmo, .wmv, .wotreplay, .wpd, .wps, .x3f, .xf, .xlk, .xls, .xlsb, .xlsm, .xlsx, .xml, .xxx, .zip, .ztmp

The Zenis cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

In case the above-stated command is executed that will make the effects of the encryption process more efficient. That is due to the fact that the command eliminates one of the prominent ways to restore your data.

This particular ransomware also searches for the following extensions:

→.win, .wbb, .w01, .v2i, .trn, .tibkp, .sqb, .rbk, .qic, .old, .obk, .ful, .bup, .bkup, .bkp, .bkf, .bff, .bak, .bak2, .bak3, .edb, .stm

In case files with those extensions are found (usually backup files), they will be overwritten three times, before they are finally erased, which makes it harder for backup programs to work.

If a computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially restore some files back to their normal state.
