Zyka Ransomware – Infection
Zyka ransomware could spread its infection via different methods. The payload file that initiates the malicious script for this ransomware, that in turn infects your computer system can be circling the Internet at the moment of writing this article.
Zyka ransomware might also distribute its payload file on social media and file-sharing networks. Freeware found on the Web can be presented as helpful but could also hide the malicious script for this cryptovirus. Don’t open files right after you have downloaded them, especially if they come from dubious sources like links and emails. Instead, you should scan them beforehand. Run a scan with a security tool, while also checking the size and signatures of the files for anything unusual. You should read the tips for ransomware prevention thread in the forum.
Zyka Ransomware – Description
Zyka ransomware is also a cryptovirus. Some malware researchers think that the virus might be written with Visual Basic. The extension .lock is to be appended to all files that become locked after the encryption process finishes.
Zyka ransomware could make entries in the Windows Registry to achieve persistence, launch and repress processes in Windows. Some entries are designed in a way that will start the virus automatically with each launch of the Windows Operating System.
The ransom note will appear right in the middle of the encryption process. The note is written in English and gives details about what the ransom is, along with other instructions about what it will take to restore your files. The note’s background is a Guy Fawkes’ mask, which has been used by other ransomware developers. You can view the ransom message that loads after file encryption down here:
That ransom note reads the following:
You are the victim of Zyka
Your important files encryption produced on this computer: photos, videos, documents etc. Here is a complete list of encrypted files, and you can personally verify this.
Encryption was produced using a unique public key AES that generated for this computer. To decrypt your files you need to obtain the private key.
The single copy of the private key, which will allow you to decrypt the files, located on a secret server on the Internet, the server will destroy the key after 72 hours.
After that nobody and never will be able to restore files.
To obtain the private key for this computer which will automatically decrypt files, you need to pay 170 USD /170 EUR to the bitcoin wallet below.

It you do not have bitcoins you can buy them from localbitcoins.com
Thank you!
Unlock Freely 150 files
The note of the Zyka ransomware states that your files are encrypted with the AES encryption algorithm. A ransom sum of 170 USD/EUR is asked as payment for unlocking your data. You are given 72 hours by the ransom criminals to unlock your files. You should NOT in any circumstance pay the cybercriminals. Your files may not get restored, and nobody could give you a guarantee for that. Furthermore, giving money to these criminals will likely motivate them to create more ransomware or do other criminal acts.
No list with file extensions that the Zyka ransomware seeks to encrypt is available yet, but files with the following extensions are the most viable to get encrypted:
→.7z, .bmp, .doc, .docm, .docx, .html, .jpeg, .jpg, .mp3, .mp4, .pdf, .php, .ppt, .pptx, .rar, .rtf, .sql, .tiff, .txt, .xls, .xlsx, .zip
Every file that gets encrypted will receive the same extension appended to every one of them, and that is the .lock extension.
The Zyka cryptovirus is quite likely to delete the Shadow Copies from the Windows operating system by utilizing the following command:
→vssadmin.exe delete shadows /all /Quiet
Read on through and check out what type of ways you can try to potentially restore some of your data.
