Nibiru ransomware is a malicious program designed to encrypt all personal data on the computer and the connected networks and then demand ransom for its return. Once inside the system, it encrypts all personal pictures, videos, documents, archives, and other files by using a combination of AES + RSA encryption algorithms, which also appends a .Nibiru extension in the process. Victims can no longer access these files and require a unique key that only cybercriminals who deployed the ransomware have access to.
