What is Corona ransomware?
The malware analyzed by WhiteDefender, a research and development company focused on ransomware security, is Corona ransomware.
Corona is designed to encrypt files and change their extensions, rendering them unusable.
The Corona ransomware not only encrypts files, but also appends the extension (.corona). For example, a file named "file.jpg" will be renamed to "file.jpg.corona," and "2.xlsx" will be renamed to "2.xlsx.corona." It also creates a ransom note (_README.txt) containing the ransomwares demands.
A ransom note is a note that contains instructions that you must follow.
is to use a reliable anti-ransomware program.
