Brain Cipher Ransomware is a type of malware that encrypts the victim's computer files and demands a ransom payment in order to restore the files. This ransomware uses a strong encryption algorithm to secure the infected files, making it difficult to recover them without the correct decryption key. After encrypting the files, Brain Cipher Ransomware will display a ransom message containing instructions on how to pay the ransom and obtain the decryption key. It is important to note that paying the ransom does not guarantee file recovery and may also encourage further criminal activity. Therefore, the best way to protect oneself from Brain Cipher Ransomware is by maintaining device security, avoiding clicking on suspicious links or attachments, and regularly backing up important files.
