CryPy ransomware virus. How to remove? (Uninstall guide)

removal by Olivia Morelli - - | Type: Ransomware

CryPy ransomware description

CryPy virus is one of a few ransomware examples that are created using Python programming language. The family of these threats has already been named as “Pysomwares”. However, this group includes only several members – Fsociety virus and Fs0ci3ty ransomware. It is known that CryPy ransomware utilizes AES-256 encryption algorithm to lock victims’ files. It works slower than typical crypto-ransomware threats since it addresses its C2 server when encrypting every individual file. While encrypting victim’s files, this virus renames every single file by adding CRY prefix and scrambling the file name by adding .cry file extension. The encryption is initiated with the help of encryptor.py file and the tracking of Windows errors is enabled by using boot_common.py. These files are compromised right after the installer enters the target computer system. Once the encryption procedure is finished, the virus leaves a ransom note called README_FOR_DECRYPT.txt. This file contains instructions on how to contact ransomware authors and decrypt data. The note of CryPy ransomware states:

IMPORTANT INFORMATION

All your files are encrypted with strong ciphers.
Decrypting of your data is only possible with the decryption program, which is on our secret server.

The rest of the ransom note explains that the virus will delete a random file every 6 hours, and, in 96 hours, it will damage the decryption key. It is believed that these claims should encourage victims not to take too long while trying to decide either to pay the ransom or not. The virus does not include payment address in the message but provides two e-mail addresses – m4n14k@sigaint.org and blackone@sigaint.org. The victim is asked to write an email to either one or another e-mail address and receive the identification code. If you are looking for a solution to recover your files without paying, sadly, we cannot say that there is a free CryPy decrypter available. However, that does not mean that victims should pay the ransom. They can recover their files from backup or rely on special programs that are supposed to help people with files’ recovery. However, before you try any of these options, make sure you remove CryPy malware first. For that, we strongly suggest using the Reimage software.

When did this virus attack my computer?

CryPy malware spreads via malware-laden ads, malicious email campaigns and also exploit kits. There are only three actually useful pieces of advice we want to share with our readers. First of all, back up your files. Backups help to restore data in case you accidentally install malware on your computer. Backups should be kept on external devices stored separately from PC. Second, use a trustworthy anti-virus solution. Install a program with real-time protection feature and, if possible, use it together with anti-malware software. This will help you prevent viruses from attacking your PC. Lastly, keep all your software up-to-date. Criminals can easily hack your PC if you keep vulnerable old programs (without installing their security updates) on the system. Besides, avoid clicking on suspicious and aggressive ads, links, and do not open emails sent by unknown people. If you do not follow these tips, then there is no surprise why you have to deal with CryPy removal now. Please, be more careful and protect your computer – speaking of ransomware, all security experts agree that prevention is better than the cure!

How can you remove CryPy ransomware?

CryPy virus is a malicious software that should be eliminated from the system as soon as possible.
