What is Mira ransomware? And how does it execute its attack?

Mira ransomware is a file-encrypting virus which according to security experts, is a new variant of Mercury ransomware. This new Mercury variant uses a “.mira” extension to mark its valuable data in a targeted machine. Nothing much has changed in this new variant except for the extension it uses and some minor changes in the ransom note. Other than that, it still executes its attack the same way as it did before.

Once it infiltrates a computer, Mira ransomware will drop its malicious executable file in either the %AppData% or %LocalAppData% folders. These folders is also where the crypto-virus creates a file with a random name. It then establishes a connection to a Command and Control remote server where it downloads some of its components and puts them into system folders. After dropping its malicious components, Mira ransomware will use them to control system processes as well as use them for the data gathering and stealth protection modules. In these modules, Mira ransomware will collect data in the system and process them for the second module where it scans the system in search for security programs and antivirus programs that could interfere with its attack. It also alters some entries in the Windows Registry allowing it to run automatically whenever users turn on their computers. After the system modifications are completed, it starts the encryption using both AES and RSA ciphers in locking its targeted data. Following data encryption, it appends the .mira extension to all the compromised files and drops a text file named “!!!READ_IT!!!.txt” which contains the following content:

“ALL YOUR DATA WAS ENCRYPTED

If you want to recover your data:

1.Send your personal ID to our emails.

2.You can send us 1 small file for test decryption.

3.After payment you will get decryption tool and opportunity to recover all your data.
