What is a CERBER file?

A CERBER file is a file encrypted by Cerber ransomware, a virus used by cybercriminals to hijack a user's computer files. It contains a user's personal file, such as a .DOC, .JPG, or .MP3 file, encrypted with AES-265 and RSA methods. CERBER files became popular in 2016 and are similar to .LOCKY and .ZZZZZ files that are created by Locky ransomware.

More Information

The Cerber virus is highly dangerous malware. It is often referred to as ransomware, where the purpose of the virus is to take your files hostage and force you to pay bitcoins to the perpetrator in order to decrypt your files. The virus is a trojan horse that is commonly spread through spam emails that include infected attachments or malicious links. Once the virus affects your computer it begins scrambling your files, renaming them, and encrypting them. When encrypting your files, the virus creates .TXT, .HTML, and .VBS files that contain instructions for paying the criminals. These files are placed in each folder that contains CERBER files.

How to open a CERBER file

You can use the Trend Micro Ransomware File Decryptor for decrypting CERBER files. However, it is important that you remove the Cerber virus before decrypting the files. You can remove the virus manually or by using antivirus software. Also, if you have a backup of your files you can execute a full system restore.


FileInfo.com recommends you never pay a ransom to decrypt files encrypted by ransomware. Paying a ransom encourages ransomware distributors to continue their efforts, and there is no guarantee that paying a ransom will give you access to your files. Instead, you should restore your data from a recent backup created before the ransomware infected your computer.
