This article has been created to help you remove the .MIKOYAN file ransomware and try to restore files encrypted with AES-256.
A ransomware virus, displaying a pop-up, named MIKOYAN ENCRYPTOR has been reported to encode files on affected computers by using the AES-256 encryption algorithm. The ransomware infection uses multiple different methods to infect a computer and after it has encrypted the files, .MIKOYAN demands victims to pay the hefty ransom fee of 1 BTC to restore access by receiving decryption software from the cyber-criminals. In case you have been infected by the .MIKOYAN file ransomware, we strongly advise you to pay attention to this material.
Threat Summary
Name
MIKOYAN
Type
Ransomware
Short Description
Encrypts files on infected computers using AES-256 cipher and demands 1 BTC from victims to decrypt the files.
Symptoms
The victim may see a pop-up type of window, named MIKOYAN DECRYPTOR which has the ransom instructions. Also files are appeanded the .MIKOYAN file extension to them.
Distribution Method
Via an Exploit kit, Dll file attack, malicious JavaScript or a drive-by download of the malware itself in an obfuscated manner.
Windows Data Recovery by Stellar Phoenix Notice! This product scans your drive sectors to recover lost files and it may not recover 100% of the encrypted files, but only few of them, depending on the situation and whether or not you have reformatted your drive.
How Does .MIKOYAN Infect?
The infection process of .MIKOYAN ransomware is very similar to other ransomware infections out there. The malware may take advantage of massive spam campaigns that redistribute malicious attachments as well web links that lead to the download of the infection files. Such e-mails are cleverly orchestrated in a manner that aims to convince users to open the attachment, for example:
Besides via e-mail, the .MIKOYAN ransomware virus may also be replicated via multiple other methods such as:
Exploit kits.
Via a previous infection with a botnet or a Trojan.
Through fake installers, flash player updates or other setup wizards.
Via a fake key generators or license activators uploaded on torrent websites.
.MIKOYAN File Virus – Malicious Activity
Once this ransomware infection has already become active on a computer, the .MIKOYAN virus drops it’s malicious payload files. They are often located in the following Windows directories:
%Common%
%AppData%
%LocalLow%
%Local%
%Roaming%
Besides the main executable of the MIKOYAN ransomware, named MIKOYAN.exe, the virus may also drop other malicious files that exist under different names, often randomly generated ones.
To run on startup, the MIKOYAN ransomware may also modify the Windows Registry editor, more specifically the Run and RunOnce registry keys:
In addition to this, the ransomware infection may also delete the shadow copies on the infected computer. This is achievable by executing a variation of the following administrative Windows command lines as administrator:
For the encryption process, .MIKOYAN ransomware takes advantage of multiple different techniques, one of which is an encryption mode, connected with the algorithm it uses – AES-256. This encryption mode is focused primarily on replacing blocks of data on the original files with data from the cipher, making the file seem corrupt and unreadable. The targeted files by the .MIKOYAN ransomware virus which it encrypts may be among the following:
After the encryption process has completed, the ransomware sets a .MIKOYAN file extension to the files encrypted by it:
After the file extension is added, the virus displays the following ransom demands in it’s ransom note:
Warning! Your downloaded files had been encrypted with a AES-256 enciyption key. If you want your files back send 1 Btcoins in the adress below. BITCOIN ADDRESS: Need help? contact me. EMAIL ADDRESS : [email protected] Good luck before it gets encrypted with RSA-4096 ENTER DECRYPTION KEY

4. Try to Restore files encrypted by MIKOYAN
Try to Restore Files Encrypted by MIKOYAN
Ransomware infections and MIKOYAN aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that these methods may not be 100% effective but may also help you a little or a lot in different situations.
Method 1: Scanning your drive’s sectors by using Data Recovery software. Another method for restoring your files is by trying to bring back your files via data recovery software. Here are some suggestions for preferred data recovery software solutions:
Method 2: Trying Kaspersky and EmsiSoft’s decryptors. If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:
To restore your data in case you have backup set up, it is important to check for Volume Shadow Copies, if ransomware has not deleted them, in Windows using the below software:
Method 4: Finding the decryption key while the cryptovirus sends it over a network via a sniffing tool.
Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:
