CryPy Ransomware Removal Guide

Do you know what CryPy Ransomware is?

CryPy Ransomware is a program whose sole purpose is to encrypt your personal files and then offer you to purchase a decryption key to decrypt them. However, you should not pay it and remove this program instead because you might not get the decryptor once you have paid the ransom and there is no way of knowing whether it will work if you do get it. This program can infect your computer if it is not protected by an anti-malware program, so make sure that it does have such as application to minimize the possibility of an infection. In this article, we will cover CryPy Ransomware’s distribution, functionality, and removal. So, without further ado, let us begin.

Let us begin with this application’s disruption methods. Our security experts have revealed that the majority of infections are a result exploit kits secretly downloading this ransomware’s executable. Malware researchers say that this ransomware is distributed in a drive-by attack-style infection when a website redirects to a malicious website containing the exploit kit. The exploit kit is set to scan the web browser for vulnerabilities and security loopholes and it usually, targets Java and Flash plug-ins to infect the computer. Furthermore, our researchers have received information that this ransomware can infect your computer in a DLL (Dynamic Link Library) file attack. Malicious URLs have scripts that secretly download modified DLL files that replace original Windows DLL files which, in turn, are set to download this ransomware.

Once on your computer, CryPy Ransomware will scan all of the hard drives on it and begin encrypting the files. We want to inform you that it is set to encrypt more than a hundred file types and they include but are not limited to .7z, .asp .avi, .bmp, .cad, .cdr, .doc, .docm, and .docx. All of the targeted files are said to be encrypted with the AES-256 encryption algorithm which is a very strong encryption method as it is, but this ransowmare’s developers went further and configured this ransomware to use a different key for each file and sends all of the keys to the C2 (Command and Control) server. The encryption takes much longer in this case, but it makes sure that the files could not be decrypted using a third-party decryption tool. Thus, unfortunately, the only way to decrypt the files is to purchase the decryption program offered by this ransowmare’s developer.

Once the encryption has been completed, CryPy Ransomware will create a ransom note named README_FOR_DECRYPT.txt and either drops it on the desktop or make copies of it in every folder where files were encrypted. In short, this ransom note says that you have to contact the developer with one of the two provided email addresses and purchase the decryption key (most likely using the Bitcoin cryptocurrency.) To make matters worse, this application is set to delete a file every 6 hours and erase the decryption key after 96 hours, so decrypting the files will be impossible after that. In any case, we do not recommend purchasing the decryptor because you might not get it or it might not work.

In closing, CryPy Ransomware is a clear-cut case of a typical ransomware whose objective is to encrypt your files and demand money for the decryption tool. Unfortunately, since it generates a different key for each file makes them difficult to decrypt if not impossible entirely. A third-party decryption tool is unlikely to cope with all those unique keys. You can, of course, try to pay the ransom, but there are no guarantees that your files will be decrypted. Therefore, we recommend using SpyHunter to locate and remove this program’s executable or just find it and delete it manually.

How to get rid of this ransomware

  1. Find the executable file using SpyHunter.
  2. Right-click it and click Delete.
  3. Delete all copies of README_FOR_DECRYPT.txt
  4. Empty the Recycle Bin.

In non-techie terms:

CryPy Ransomware is a typical ransomware-type application designed to encrypt all of your personal files on your PC and then offer you to buy the program for decrypting them. In short, it is nothing more than a money extortion scheme and you should not comply with the developer’s demands because you might not get your files back regardless of whether you pay. Therefore, we recommend that you remove this ransomware manually or using SpyHunter.
