Cerber 5.0.1 Ransomware – More Information

What is characteristic for the 5.0.1 version of the Cerber virus is that it is not very different in comparison to other updates of Cerber. In fact, the malware may be distributed via the very same RIG-V exploit kit, typical for the 5th version of Cerber.

The new modifications of this RIG EK include changed web links and highly obfuscated infection code in them that allows to cause a successful infection which is unnoticed by any anti-virus software. The new exploit kit which is characterized by the letter V, and outlined by researchers as a “VIP” type of exploit kit is believed to have RC4 encryption for payload obfuscation.

This means that Cerber ransomware may use .hta, .html or .htm files with which it can cause an infection via a spam message sent out to the users, just like it’s older versions did.

But another method of the infection being caused is also via malicious web links uploaded online and sent out as a message on either social media or other places that favor third-party web links.

Not only this, but Cerber ransomware also has the ability to cause an infection via thumb drives and other methods if executed hands on. This is more common when an attack versus an organization is conducted. It is also likely due to the fact that the Cerber 5.0.1 variants I also more focused on encrypting databases besides widely used types of files.

Cerber 5.0.1 – Encryption and Notification

After an infection the 5.0.1 version of Cerber ransomware may stop any actively running processes on the user that are related to:

  • MySQL databases.
  • Oracle databases.
  • Microsoft Access databases.

Not only this but Cerber 5.0.1 may also delete any shadow volume copies or other forms of backup on the compromised computer. This is technically achievable by executing the vssadmin command, for example:


After this modification n has been completed, the Cerber ransomware begins the encryption process. It may conduct it on system boot while antivirus software has not yet started or it may immediately perform the encryption upon execution. Either way, the following file types may be affected by Cerber:


To encrypt the files on the compromised computer, Cerber ransomware uses advanced encryption algorithms. It uses the combination of Advanced Encryption Standard (AES) and Rivest-Shamir Adleman (RSA). This results in the producing of a unique decryption key corresponding specifically for the particular infection and this key is sent to the cyber-criminals’ command and control servers.

After this has been performed, Cerber 5.0.1 performs it’s standard activity – changes the filenames and the file extension of the encrypted files to completely random:

Cerber 5.0.1 – Conclusion, Removal and File Decryption

As a bottom line, malware researchers strongly advise users not to pay any form of ransom to the cyber-criminals primarily due to the fact that collaborating with them may not get your files back and you support their criminal activities to further update Cerber. In fact, the variant 5.0.1 Is likely not the last Cerber variant we will see, because there will be many more after it, mainly because of the large affiliate network, built up by Cerber’s creators. This rapid changing of versions of the two big ransomware families, Locky being the other one is a headache for malware researchers and many feel concerned that this “trolling” may continue.

    Dear all,
    all my documents are encrypted by cerber ransomware 5.0.1.
    Files changed to .9775. Does anybody know if there is a file recovery or
    decryption program for this?

    1. AvatarBerta

      For now there is no decryption program available. The files that become encrypted are with a different extension for everybody. You can try Data Recovery Programs to see if you can restore some files. Otherwise, just save your data somewhere and wait for a decryptor.
