What is Coinmoney ransomware? And how does it execute its attack?
Coinmoney ransomware, also called “[email protected]” ransomware, is a file-encrypting threat that’s written using the Go programming language or “Golang” via a Python extension known as “py2.exe”. This python extension converts Python scripts into MS Windows executables which when executed, will spread the Coinmoney ransomware through LAN with the help of the EternalBlue exploit.
The moment it infiltrates a computer, Coinmoney ransomware will start to execute its attack by connecting to a Command and Control server where it downloads additional files for its attack. These files are used to modify and manipulate several processes in the system. It also alters some entries in the Windows Registry so it can automatically start its attack each time the affected computer is started. Once the system modifications are completed, it searches the computer for files to encrypt. After it finds the targeted files, it will begin the encryption procedure using a combination of AES 256 and RSA 1024 ciphers that would make the files inaccessible to users as the encryption modifies the files with a symmetric key. This entails a single key that could decrypt and encrypt the affected files. However, this key itself is usually encrypted with asymmetric encryption and only the developers of Coinmoney ransomware have access to it. Coinmoney ransomware appends the “.locked” extension to the affected files to mark them. It then delivers a ransom note in a text file named “README.html” which is placed on the desktop of the infected computer. This ransom note contains the following message:
“I am so sorry ! All your files have been encryptd by RSA-1024 and AES-256 due to a computer security problems.
If you think your data is very important .The only way to decrypt your file is to buy my decrytion tool .
