Cerber 4.1.3 Features

Once Cerber 4.1.3 successfully executes its malicious files, it starts a scan of all computer drives. The threat searches for all file types that are included in its target data list. When it detects a match it automatically starts encrypting the file. By utilizing strong encoding ciphers like AES, RSA or combination of both, it encrypts the files making them inaccessible. All video files, documents, images, audio files, databases stored on either internal or external drives and on connected cloud services can be affected by the malicious mechanism of Cerber 4.1.3 ransomware. At the final step of the encryption process the treat generates an unique extension that has four random symbols and attaches it at the end of the original file name. For example, a file with a name ‘data.doc’ will be given the unique name ‘data.doc.bed5’. Then the file becomes unable to be opened by any program.

Next, the threat displays a ransom note that serves as a notification for the victims. It informs them that they have to pay a certain amount of money if they want to receive the special “Cerber decryptor” software. This software will help them to access the files locked by Cerber 4.1.3. Usually attackers demand the ransom amount in Bitcoins. The wallpaper might be providing URLs to Onion network hosts that lead to payment pages.
