What is Scarab-Bomber ransomware? And how does it execute its attack?

It seems that developers of Scarab ransomware are feeling quite productive as a new Scarab variant was once again spotted recently. This new variant is known as Scarab-Bomber or Bomber ransomware. Just like the other variants, nothing much has changed with this new one save for the extension used to mark the encrypted files and its ransom note but the execution of its attack remains the same.
Once it manages to infiltrate a computer, it will establish a connection to its remote server and download malicious files that help it in executing its attack. These files may be placed on system folders with the purpose of repressing any programs that might get in the way. These files are also used to modify some registry keys and sub-keys that will allow the crypto-virus to automatically run on every system startup. After that, it begins to scan the entire drive of the computer in search for files with specific formats. Once it finds these files, it will encrypt them using the AES cryptography. Following data encryption, Scarab-Bomber ransomware will generate a file named “КАК ВОССТАНОВИТЬ ЗАШИФРОВАННЫЕ ФАЙЛЫ.TXT” containing its ransom note. Here’s the ransom note translated into English from Russian:
“YOUR FILES ARE ENCRYPTED!

How does Scarab-Bomber ransomware proliferate?
