removal by Olivia Morelli - - | Type: Ransomware

The characteristics of Cerber3 virus

Since the end of summer 2016, .cerber3 file extension virus (or Cerber3 ransomware virus) threatens computer users, takes their files to hostage and demands paying the ransom. Some victims are still waiting for the free data recovery option, and sadly, we still do not have good news. It seems that after the failure with Cerber 2.0 hackers took their time to fix the flaws in the code[1] and continued developing dangerous cyber threats. The second version of Cerber virus has been defeated[2] by cybersecurity company Check Point, and victims can restore their files using a free decryption software. The third attempt to create a hazardous cyber threat was successful. Cerber3 malware is still not decryptable and uses improved distribution methods. After the infiltration, ransomware starts scanning computer system and encrypts targeted files with a sophisticated encryption algorithm. All files are damaged with .cerber3 file extension. Since then users lose access to their files and notice a ransom note left by the virus. In the # HELP DECRYPT #.txt victims can learn about the damage that has been done to victim’s photos, images, audio or video files, documents, and other important data. The message also includes how victims can solve all problems caused by .cerber3 file extension virus. In order to get back their files, people have to transfer some Bitcoins via particular payment website. However, paying the ransom is not as easy as you may think at first. Victims can access this site only via Tor browser[3] which provides anonymity.

While reaching out for your credit card, think whether you want to pay that ransom[4]. We understand that you need your personal files and that they are very important to you, but remember that cyber criminals are people that are not worth your trust. Do you believe that they actually provide the decryption program and that it is going to be malware-free? Sadly, cybercriminals might send a malicious component alongside the decryption software, making your computer vulnerable and exposed to risks. Besides, another reason not to pay is the fact that cyber criminals continue their malicious activities only because victims keep paying them. Instead, you should fight back and not pay up! Remove .Cerber3 file extension virus from the system and do everything to prevent a repetition of such situation. Malware researchers might be able to create a free decryption tool soon, so we definitely do not recommend you to waste your money by paying these crooks. For Cerber3 removal, we recommend using a Reimage software.

Ransomware distribution methods

.Cerber3 file extension virus is distributed with the help of the trojan horse called Betabot[5]. It attempts to trick users to install it without realizing that it is a dangerous file. Moreover, the ransomware meddles with your security applications and download settings. In short, you may run into trouble removing the virus. Therefore, no need to worry as you can use our access recovery guidelines provided below the article. You can infect your PC with this malware after visiting unsafe, suspicious or fake Internet pages, opening questionable emails or clicking on forged links. If you are ever unsure about the safety of the Internet website that you are going to visit, just do not enter it. If you do not know the person who had sent you an email, do not open it, or its attachments. Keep your computer protected at all times. Cyber criminals use new techniques now to deceive computer users, and several different ransomware prevention actions should be taken in order to protect the computer system from this virus. There are some tips on how you can protect your computer and your files from being impacted by ransomware virus:

    • Install a good anti-malware software. It is the only one that can identify the ransomware and prevent it from invading the PC system without your knowledge.
    • Keep all your programs up-to-date. It does not matter what sort of programs you have on your PC, make sure that they are all updated to their latest versions. It is a good idea to enable automatic updates – this way, these programs will be instantly updated as soon as their developer releases a new update.
