    What is encryption?

We’ve already tackled the Cerber Ransomware Virus. Then we came across the .Cerber2 Virus. It’s only fair that we provide a removal guide on the brand new .Cerber3 as well. As you can see, ransomware-type infections are incredibly popular these days. Hackers seem to be constantly working on this type of viruses. As a result, the Web is now infested with harmful, file-encrypting programs. Ransomware is probably the biggest cyber pest out there. It’s the perfect combination of stealthy, aggressive and malicious. It gets activated immediately and causes a real mess. Yes, you’ve downloaded a particularly dreaded infection. .Cerber3 doesn’t differ from the classic ransomware pattern. It uses a complicated encrypting cipher to lock your files. All of your files. Pictures, music, videos, Microsoft Office documents, etc. Whatever you’ve stored on your machine falls victim to the ransomware. The parasite firstly scans your PC in order to find your data. Once .Cerber3 locates the target files, it starts encrypting them ASAP. This pest utilizes the AES-256 and RSA algorithm which, to put ti mildly, is quite effective. By using the RSA-2048 key,. Cerber3 successfully makes your files unusable. Needless to say how dangerous that is, right? Thanks to the ransomware’s shenanigans, you’re unable to use your very own personal data. The virus actually changes the file format of your information. It adds a malicious file extension which replaces the original one. This extension is a crystal clear sign that you’re dealing with ransomware. .Cerber3 creates a combination of 10 random symbols and adds the “.cerber3” appendix. The parasite obviously renames your data completely behind your back. Not many PC infections seek your permission and ransomware isn’t the great exception. Its goal is to deny you access to your own files. Then .Cerber3 starts asking for money. We’re getting to the bottom of this entire cyber scheme. At the end of the day, ransomware is nothing but the nth attempt for a scam. Money is the reason why .Cerber3 is currently on board. Money is also the reason why all your private files have been renamed and locked. Every hacker’s dream is to gain effortless profit on the Web. Unfortunately, ransomware is extremely effective in that department. While encrypting your files, the .Cerber3 virus also adds a ransom message. It drops “# HELP DECRYPT #.html”, “# HELP DECRYPT #.txt” and “# HELP DECRYPT #.url” files. You will find them in all folders that contain locked data and on your desktop as well. According to these ransom messages, you have to pay 0.7 Bitcoins (400 USD) in order to free your files. Hackers are trying to blackmail you. It goes without saying you shouldn’t participate in their fraud.

How did I get infected with?

Ransomware usually gets disguised as legitimate mail. For instance, it mainly travels the Web via spam messages. Next time you spot some questionable-looking email/message, stay away from it. It is much easier to delete a corrupted email than to uninstall a virus afterwards. The parasite might claim that it was sent from a shipping company. It might also pretend to be a job application. There are endless possibilities and you should keep in mind that the Web is full of threats. You only need one single careless click in order to compromise your machine. Pay attention online and avoid what you don’t trust. Ransomware also gets spread via malicious torrents, executables and unverified websites. Long story short, infecting your PC is a very easy task so be cautious online. The virus might also have been bundled with illegitimate freeware/shareware bundles. It might have gotten installed with the help of a Trojan horse. In the future, watch out for malware on a daily basis. You won’t regret it.

However, this is actually a clever way for cyber criminals to steal your money. According to the ransom notes, you have exactly 96 hours to make the payment. Otherwise, the sum demanded reaches 1.4 Bitcoins (800 USD). Hackers want to CHARGE you 800 dollars so you could open your pictures and music. Do you think that’s fair? They promise you a decryption key in exchange for your money but could you really trust them? Crooks’ main concern is to gain revenue.
