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.

Cerber 4.1.0 virus is a new version of Cerber ransomware

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 Reimage, Malwarebytes Malwarebytes 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.
