Cerber 3 Virus – How Does It Infect

Similar to the other Cerber(Cerber Version 2) viruses, this ransomware does not limit itself to a simple executable that infects the user. Instead, it is a whole operation that is created to synchronize a variety of infection and spamming technologies and techniques into one big and successful operation, called Cerber ransomware. This includes several different tools that are being used to infect users with the virus:

  • Malware obfuscators to hide Cerber 3 ransomware’s files from any real-time protections and firewalls.
  • File joiners that may conceal the payload dropper of the virus by combining them with legitimate files, like Microsoft Office documents that have malicious macros, for instance.
  • Exploit Kits which may be used for a successful download of the directly by connecting to the command and control server of the cyber-criminals from the infected machine itself.
  • Malicious JavaScript (.js) files disguised as legitimate files that may cause the infection. Themselves.

Such tools may be used in combinatain with spamming bots or spamming services that may spread the malicious files belonging to Cerber 3 ransowmare via several different methods, mainly in the form of uploads on malicious URLs or as e-mail attachments.

Below is an example of a spam e-mail, the malicious URLs of which may lead to a browser redirect that could cause a drive-by download infection with Cerber ransomware:

Cerber Ransowmare – In-Depth Information

As soon as it has been dropped on the computer, Cerber 3 may be dropped on key Windows folders with files that have different names. Several directories it may exist in are the following Windows targeted locations:

commonly-used-file-names-and-folders

Along with CryptoWall and Locky ransomware, Cerber may also modify the registry entries of infected computers, to make the malicious executable that may be different type of file (.tmp, .dll, .js, .exe) run when Windows boots up and encrypt a wide variety of files even before the antivrus program of the computer has started. The registry entries to make it run on system startup are the following keys in Windows Registry Editor:

HKEY_LOCAL_MACHINE \Software \Microsoft \Windows \CurrentVersion \Run
HKEY_LOCAL_MACHINE \Software \Microsoft \Windows \CurrentVersion \RunOnce
HKEY_CURRENT_USER \Software \Microsoft \Windows \CurrentVersion \RunOnce HKEY_CURRENT_USER \Software \Microsoft \Windows \CurrentVersion \Run

As soon as Cerber 3 ransomware’s encryption, begins the user is doomed. The virus may immediately scan for a wide variety of file types and encrypt them as soon as it detects them:

Cerber ransomware may not only encrypt almost any file on your computer beside the files essential to run Windows, but the virus may also change the names of the files as well. Files encrypted by Cerber 3 ransomware do not only have the .cerber3 file extension but they also have completely random names, preventing them from being identified. A tweetpost by the malware researcher PhysicalDrive0 indicates how the files look after encryption by Cerber 3 ransomware:

physicaldrive0-twitter-post-files-encrypted-by-Cerber-3-sensorstechforum

To encipher the files, the 3rd variant of this virus may use RSA or AES encryption algorithms and the virus may even use the so-called Cipher Block Chaining(CBC) mode which protects the encrypted files by permanently breaking them if you try to tamper with their code structure (decrypt them, for example).

After encrypting the files, Cerber 3 ransomware drops a ransom note, named # HELP DECRYPT #.txt that is primarily focused on notifying the user his situation is very dire.

Another variant of Cerber 3 employs a different ransom note, known as @___readme___@.txt:

cerber-new-ransom-note-sensorstechforum

Contents of the @___readme___@.txt note.

cerber-new-ransom-note-sensorstechforum

The ransom note may be located on every folder containing encrypted files or on the desktop and even on the %Startup% folder so that it opens every time Windows runs.

Furthermore, after the encryption and notification process is complete, Cerber ransomware may generate a unique decryption key which it sends to the cyber-criminals’ command and control servers. After this procedure is done, the malicious files of Cerber ransomware may be deleted to avoid any researchers from peeking into the virus.

The ransom instructions of the virus may lead to a Tor-based web page, similar to the following:

What is a File Virus and How Do You Remove it?

A "file virus" (ransomware) is a type of malicious software that infects a computer system and encrypts its files and data, preventing the user from accessing them unless they pay a ransom. The virus is usually spread through malicious links, emails, and downloads from untrusted websites. To remove such a virus, it is best to use professional security software to detect and remove it, as well as to restore any encrypted files. It is also important to practice safe computing by avoiding suspicious links, emails, and downloads, and keeping your computer and software up to date with the latest security patches.

Different Types of File Viruses and How to Understand Them?

File viruses are a type of malicious software that can attach themselves to files, such as documents, spreadsheets, and images, and then spread themselves to other computers. The most common types of file viruses are boot sector, macro, file-infecting (ransomware), and multipartite. Each type of virus has its own set of characteristics and behaviors, which can help users identify them and take the necessary steps to protect their data from infection.

What Steps Should You Take to Protect Your Computer from File Viruses?

To protect your computer from file viruses, the first step is to install up-to-date antivirus software. Make sure you keep the software updated and run regular scans to detect and remove any viruses.

      Hello, nico

      At the moment we are testing the older decryptor on a testing computer. You can try it also yourself. Here are the instructions:

      sensorstechforum.com/decrypt-encrypted-files-cerber-ransomware

      Bear in mind that these instructions are for the first variant of Cerber. However if this turns out to be a modified version of the first variant but still using the same strategy, there may be a method to decrypt the files soon.

      Well, according to these guys, the situation with the HASH’s is quite relative: invincea.com/2016/06/hash-factory-new-cerber-ransomware-morphs-every-15-seconds

    I will paciently wait for that people who work hard to provide a solution for us but I have a question to ask, if anyone could answer it. Why cerber encrypted videos can be reproduced and photos can not be seen? The encryption does not affect to videos but in the name and photos are fully encrypted?

    Thank you very much.

      Hello, it seems that either the code of the ransomware may be poorly written or there is some type of defense that stops it from fully encrypting everything. Make sure to backup all of the files while you wait for a decrypter, even the ones that you can reproduce, because you may need them.

    Good day ! Base in my case all of my excel files are encrypted but my video and pictures are okay.

      Hello Khalid,
      It seems that something interrupted the ransomware virus while it was encrypting files. It could be your antivirus protection (if you have any) or other type of protection. It is unfortunate that your excel files are encrypted, do you have any features that remember previous versions of excel documents you worked on, like shadow copies?

      Reply

        Hello Sir,
        There is no shadow copies. We try to recover the files but all we recover are the encrypted files. Is there any solutions ?

        Sir can you teach me how to recover the shadow files.Thank you

    Vencislav Krustev buongiorno,
    la prego, sa dirmi come decriptare i file con estensione cerber3? Ho bisogno di un suo aiuto.
    Grazie

    1. Vencislav Krustev

      Ciao, purtroppo a questo punto non vi è stato un decryptor rilasciato per i file crittografati da Cerber3 ransomware. Questo è il motivo per cui vi consiglio di provare programmi di recupero dati per ripristinare almeno alcuni dei file e seguire questo articolo. Vi aggiorneremo non appena c’è un decrypter. Grazie.

      the solution (in portuguese Brasil): faça um backup e formate o sistema para liquidar o virus. Após renomeie cada um dos arquivos com a extensão de origem por exemplo: sdfsoid.cerber para xxx.xls

      Reply

    the solution (in portuguese Brasil): basta renomear o arquivo de origem e o problema da criptografia está acabado. Por exemplo 124usxo.cerber para xxx.docx
