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

Horsia ransomware is a new variant of the infamous Scarab ransomware which is why it is also referred to as “Scarab-Horsia” ransomware. It is designed to lock important files in an infected PC. Once its malicious payload is activated, it will begin to carry out its attack by running malicious scripts in the system. It then runs through the system files looking for certain files to encrypt. According to researchers, Horsia ransomware mostly encrypts files that are generated by users such as images, videos, documents, audio files, database, and so on. After it finds the files it’s looking for, it will start the encryption process and employ the AES encryption algorithm in locking them. Once data encryption is completed, it will append the .horsia@airmail.cc file extension to each one of the encrypted files. The ransomware then releases a ransom note in a file named “HOW TO RECOVER ENCRYPTED FILES.txt” which contains the following message:
