CryPy Ransomware

What is CryPy Ransomware?

A new ransomware-type application that has come to be known as CryPy Ransomware has been wreaking havoc recently, infecting thousands of computers, encrypting their files and asking users to pay a ransom to decrypt them. It is recommended that you remove this infection if it happens to infect your PC because there is no guarantee that you will get the promised decryption program once you have paid the ransom and there is no telling whether it will work even if you get it. This malware is all about money, as its developer wants you to purchase the decryption key (most likely in Bitcoins) for a sum that is revealed only after contacting the developer via email.

Where does CryPy Ransomware come from?

Truth be told, there is literally no information about CryPy Ransomware’s origins. We do not know where it comes from or which country it is set to target. Nevertheless, we have some unverified information pointing to its possible distribution methods. Our security experts say that this ransomware can be disseminated using exploit kits featured on infected websites that run a malicious JavaScript that secretly downloads this ransomware on your computer. Also, they say that it can enter your PC as a result of a DLL hijacking. DLL hijacking occurs when a DLL file is replaced by a malicious file. However, the means by which this hijacking occurs have yet to be known. In any case, both distribution methods ensure that you do not notice the infection, and if your PC does not have a powerful anti-malware program, then this ransomware cannot be stopped.

What does CryPy Ransomware do?

CryPy Ransomware is configured to encrypt most of the files on your computer with an AES-256 encryption key. However, there is more to this than you might think. To make matters even worse, its developers have set up this ransomware with a C2 (Command and Control) server. This ransomware calls the C2 server for every file it encrypts. This server generates a 32-character password for each encrypted file. Therefore, decrypting the files without the appropriate decryption program is practically impossible as there are too many passwords to crack. Furthermore, it writes the encrypted form of the file and replaces the original one.

If you want to know whether a particular file has been encrypted, take note of the file name that is set to be changed to CRY<random characters>.cry attempting to open a file or run an executable will, obviously, result in error. Once the encryption is complete, this ransomware will create a file named README_FOR_DECRYPT.txt that states that your files have been encrypted and that it will delete a random file every 6 hours. Furthermore, it says that it will delete the decryption key stored on the C2 server if the payment is not made within 96 hours. So the developer uses scare tactics to compel you to purchase the decryption tool, but there are no guarantees whatsoever, so we think that eradicating CryPy Ransomware is something that you should consider.

How to remove CryPy Ransomware?

If you have made the decision to remove CryPy Ransomware, then we invite you to do so using our recommended anti-malware application called SpyHunter because it will wipe out all traces of it. However, you can opt for locating and eradicating the files manually, but we want to inform you that its main executable can be placed anywhere on your PC, so we suggest using our suggested anti-malware program to at least locate the malicious file for you because it will show you its file path.
