What is MegaLocker ransomware? And how does it carry out its attack?

MegaLocker ransomware is a dangerous file-encrypting virus that was recently discovered. It is encrypt valuable files in a targeted machine using a sophisticated encryption algorithm, AES-CBC 128 and appends the “.crypted” extension.
It begins to execute its attack by connecting to a remote server controlled by the attackers. From there, it downloads malicious files and places them on system folders. These malicious files are then used to make sure that no program installed in the computer can interfere with the attack. Some of these files are also used to make alterations in the registry so that the crypto-malware can run automatically on every system startup. It then scans the computer in search for its targeted files. It may target documents, database, images, videos, audio files, archives and other user-generated files. After the encryption, it adds the .crypted suffix at the end of every encrypted file’s name. Following the encryption, it drops a text file named “! DECRYPT_INSTRUCTION.txt” which contain the ransom note that states:
“All your files were protected with strong encryption using AES cbc-128 using MegaLocker Virus.
