CryPy Ransomware

Our security experts suggest that CryPy Ransomware is probably a dead ransomware, in a way that it is no longer active, but just in case you may encounter a live version in the wild, we are writing this description for you to tell you how to remove it. The program is actually just like any other generic ransomware infection out there. It comes to your computer to push you into paying money for the decryption key, but we would like to convince you there is no need to do that as there is a good chance the program would not issue the decryption key in the first place.

One of the main reasons this program probably cannot issue the decryption key is that its main server does not seem to be active anymore. What’s more, even if it were active, it does not mean you should scramble and spend your savings just so that these cyber criminals could achieve their aims. There are other ways to restore your files, and you should explore all the potential options instead of doing what CryPy Ransomware wants you to. So now that we have established that paying is not an option here, we can take a closer look at this infection and how it works.

Usually, ransomware infections travel via spam email campaigns. That is the most common ransomware distribution method in use. However, CryPy Ransomware is slightly different. It uses other “means of transportation” so to speak. Our research shows that the program may come through an Exploit Kit, a DLL file attack or malicious JavaScript. An exploit kit is a type of software that runs on particular websites. Exploit kits identify vulnerabilities on these websites and then exploit them by executing a malicious code. For instance, you may encounter a pop-up on some random website that has an exploit kit or a malicious JavaScript in it, and clicking this pop-up (even if it happens accidentally) may result in a computer infection.

Of course, users are not aware when or how they get infected with CryPy Ransomware, but they will definitely know that the ransomware has arrived because it is very explicit about its presence. Upon the execution, the program will run a full system scan, looking for appropriate file types to encrypt them. The program will use the AES-256 encryption to scramble your files. This algorithm was first developed to protect important data from being read or stolen, but now it is always being used by cyber criminals to bully innocent users into giving away your money.

Once the payload has been unleashed, all the affected files will have their titles changed to CRY[randomcharacters].cry. So it will be really easy to see which files were affected by the malicious program. The peculiar thing about this program is that it uses a different key to encrypt every single file, and then it sends those keys to its command and control server. As a result, the encryption process is for CryPy Ransomware is a lot longer than that of other ransomware programs.

The infection also creates the README_FOR_DECRYPT.txt document where it gives you two email addresses: and These are the addresses you are supposed to use to contact the criminals. They also tell you that you have 96 hours to retrieve your files; otherwise, the data will be deleted. Also, every six hours the criminals threaten to delete a random file permanently, just to push you into making that transfer.

Needless to say, you have to remove CryPy Ransomware immediately without even thinking of making that payment. You can restore your files from an external backup, and if you do not have one, you should also be able to find quite a few important files saved in your main mailbox or any other cloud storage.

Think of all the possibilities, and you will be surprised to find that you can retrieve quite a lot of data without even breaking a sweat. However, do not transfer the healthy files into your computer while the infection is still on it.

For a more efficient removal, be sure to use a powerful antispyware tool. An automatic malware removal will guarantee that CryPy Ransomware disappears along with a list of other potential threats. Your computer’s security should be one of your top priorities, so do not hesitate to invest in it.
