Crysis Ransomware

Have you recently opened an attachment from an unfamiliar sender? Have you lost the ability to open your files since then? If that is so, we believe that you might be infected with Crysis Ransomware. This malicious computer infection encrypts a list of files and does not allow users to open various programs. The program encrypts your files because the people behind it expect you to pay a ransom fee. This mode of computer infection is becoming increasingly common, and the problem is that removing Crysis Ransomware may not solve all of the issues. Please read on to find out more about this infection.

Ransomware programs first appeared in 2013 and ever since then they have been evolving into fast and cunning computer threats, all of which are created to push the innocent users into giving away their money. Programs like Crysis Ransomware can also be sold or rented out through darknet (a stealthy network that offers anonymity), so it is also possible that the people who are threatening you are not the actual creators of the ransomware. They might be simply using the application to make easy money out of you, but as an end user, perhaps you do not really care about the actual chain of this infection.

The point is that with Crysis Ransomware in your system, you can no longer access your programs because all of your program files have been encrypted. The infection makes use of the AES encryption, and only the person who has the original encryption key can help you decrypt your files. Quite often, ransomware programs “protect” themselves from being figured out by encrypting the key itself. Then the RSA encryption is used for that, and this encryption is notorious to the point it has its own “RSA problem.” To put it simply, it is very likely that the criminals who infected you are the only ones who have the decryption key, and unless you transfer the payment, you will not be able to get your files back.

Nevertheless, stop right there before you have ended up contacting the criminals. Take a closer look at the notification you see on your screen. The message is actually desktop wallpaper that was changed without your permission. The information on your desktop says that you need to contact the people behind this by a given email address. Then it says below that in case you do not receive any message within 48 hours; you should contact them via alternative email.

Now you may think that the criminals are just too eager to swindle you out of your money, but this piece of information suggests that Crysis Ransomware cannot establish a secure connection with its command and control center. If the email address that is supposed to help people contact the criminals can go offline, it means that the entire operation is highly shaky, and you may not be able to acquire the decryption key even if you pay the ransom fee. As for the amount of the ransom fee, you may need to receive the confirmation email from the program’s command and control center to find out further details.

Perhaps you are wondering how it would be possible to restore your files. Unfortunately, as of now, there is no way to decrypt them without the original encryption key. This is the most frustrating aspect of ransomware infections: we know how to remove them, but the damage they inflict on your system usually remains. This is why computer security experts always point out that the best way to protect your computer from a ransomware infection is creating a data backup on an external hard drive or some virtual storage.

Take note that the external hard drive should not be connected to your computer all the time because ransomware programs can encrypted files in all mapped drives, so if your external HDD is part of the drive list and it is connected to the infected PC all the time, there is a chance that Crysis Ransomware could encrypt the files there as well.

Save yourself the trouble of dealing with this infection by investing in a licensed antispyware tool. A computer security program of your choice will run a full system scan and delete all the potential threats at once. You may also try removing Crysis Ransomware manually by following the instructions below.
