Description of Cerber 4.1.0 ransomware virus

The creators of Cerber don’t stop: Cerber 4.1.0 ransomware started spreading

Your eyes don’t lie – Cerber 4.1.0 virus is already here. Since the appearance at the beginning of this year, the notorious Cerber virus has been updated four times now. The latest, fourth, attempt to create even stronger cyber threat might be called as a double trouble. Hackers stroke harder this time and developed two versions of the updated malware. Virus researchers have already analysed the first update, but Cerber 4.1.1 is still under investigation. However, it seems that both updates act similarly and have the same characteristics. Though, the chances to meet and greet a member of the hazardous ransomware family doubled. Cerber became a serious competitor for other widely spread malware – Locky and CryptoWall viruses. Therefore, computer users should be even more careful online and think about strengthening their computer’s security. The developers are continuously improving this cyber threat and are not willing to stop. If this file-encrypting virus corrupted your files, you should not think about anything else but Cerber 4.1.0 removal. Do not delay this procedure because ransomware might install additional malware and make your computer even more vulnerable.

After infiltration, Cerber 4.1.0 virus encrypts files using RSA and AES cryptography. Previous versions of the virus used the same algorithms as well. However, the latest version appends different file extension. After the second update, virus added .cerber2 file extension, and the third – .cerber3. This time malware generates random file extension from A-Z and 0-9 characters. Therefore, a corrupted file example.jpg after the attack will look like example.jpg.e23cr. Since then, victims cannot access any of their personal documents, pictures, audio or video files. Following data encryption, Cerber 4.1.0 malware drops the same old README.hta file. This file is a ransom note where cyber criminals inform about data encryption and decryption, explains file recovery options and provides all necessary information. If you have encountered the virus and have already read the instructions, please do not follow them! Paying the ransom might not be an effective way to get back access to your files. The aim of the ransomware is to swindle the money, so hackers usually do not bother to help victims; they just take your money and disappear. Instead of purchasing and transferring Bitcoins, remove Cerber 4.1.0 from the system. Employ FortectIntego, SpyHunter 5Combo Cleaner or other preferred anti-malware program and scan the system. Virus elimination will not restore your files, but if you have data backups, you can simply retrieve necessary files.

How does ransomware proliferate?

Cerber 4.1.0 ransomware spreads via pseudoDarkleech Rig exploit kit. When internet users click on infected content online, such as a suspicious link or aggressive ad, the exploit kit starts scanning and looking for security issues. Once it finds some flaws in computer’s protection, it drops a malicious file into the system. For this reason, it’s crucial to use a reliable and updated antivirus program and keep all your software updated. Then you reduce the risk of ransomware attack. Additionally, there’s a possibility than Cerber 4.1.0 ransomware virus might infiltrate computer when you open a malicious email attachment, click on a malware-laden ad or install/update software from questionable sources. Therefore, if you want to keep your computer safe and sound, you should watch your every click and install a reputable antivirus program.

Windows Previous Versions feature might be helpful to recover some of your files if you have enabled System Restore function before the ransomware infiltration.

  • Right-click on the encrypted document you want to recover;
  • Click “Properties” and navigate to “Previous versions” tab;
  • In the “Folder versions” section look for the available file copies. Choose the desired version and press “Restore”.

How to prevent from getting ransomware

Securely connect to your website wherever you are

Sometimes you may need to log in to a content management system or server more often, especially if you are actively working on a blog, website, or different project that needs constant maintenance or that requires frequent content updates or other changes. Avoiding this problem can be easy if you choose a dedicated/fixed IP address. It's a static IP address that only belongs to a specific device and does not change when you are in different locations. 

VPN service providers such as Private Internet Access can help you with these settings. This tool can help you control your online reputation and successfully manage your projects wherever you are. It is important to prevent different IP addresses from connecting to your website. With a dedicated/fixed IP address, VPN service, and secure access to a content management system, your project will remain secure.

Reduce the threat of viruses by backing up your data

Due to their own careless behavior, computer users can suffer various losses caused by cyber infections. Viruses can affect the functionality of the software or directly corrupt data on your system by encrypting it. These problems can disrupt the system and cause you to lose personal data permanently. There is no such threat if you have the latest backups, as you can easily recover lost data and get back to work.

It is recommended to update the backups in parallel each time the system is modified. This way, you will be able to access the latest saved data after an unexpected virus attack or system failure. By having the latest copies of important documents and projects, you will avoid serious inconveniences. File backups are especially useful if malware attacks your system unexpectedly. We recommend using the Data Recovery Pro program to restore the system.
