removal by Gabriel E. Hall - - | Type: Ransomware

MCrypt2018 ransomware is a cyber threat that can also be named CRP.Net3 ransomware

MCrypt2018 ransomware
MCrypt2018 ransomware is a cyber threat that makes a lot of changes on the computer to keep virus persistent on the system.
MCrypt2018 ransomware is a cryptovirus that encrypts data using DiskCryptor functionality and then demands to contact the developer. This threat can also be called CRP.Net3 because the main executable of this virus is called CRPDOTNET3.exe. Similarly to HDDCryptor, Bad Rabbit, MBR-ONI and other crypto viruses, the ransomware does not encrypt data[1] but locks the whole drive using the DiskCryptor utility, so there is no file appendix added to the locked files. The so-called encryption is followed by the note which is placed on the system when the user restarts the device. Then, the black window is displayed in the message stating nothing more than a suggestion to contact the criminals behind ransomware via mcrypt2018@yandex.com email address. In most cases, criminals seek to trick their victims to pay the ransom for the alleged file recovery key. However, paying the ransom as well as contacting virus developers can lead to permanent money or data loss, so you shouldn't do that.

When it comes to the main functionality of ransomware viruses, it becomes clear that MCrypt2018 virus is not such a typical cryptovirus. There is no specific encryption algorithm used to encrypt data, no file extension or ransom note – main features used by widely-spread ransomware. This particular cyber threat locks the whole disk by using DiskCryptor[2] for the process. This utility is an open-source system that allows virus developer to lock an entire hard drive of the infected device. This tool is based on the AES-256 encryption algorithm but often employs a combination of a few different methods. 

When MCrypt2018 ransomware virus infiltrates the system, it starts changing various parts of the system to keep the payload running on the device undetected for as long as possible. Ransomware can alter registry entries and place various files on the system. Data associated with this ransomware includes the following:

  • the main CRPDOTNET3.exe;
  • netpass.txt;
  • mount.exe;
  • dcapi.dll;
  • dcrypt.exe;
  • log_file.txt ;
  • netuse.txt.;
  • etc.

Additionally, MCrypt2018 ransomware encrypts the whole hard disk and lets you know about itself only the process is finished and your data on that disk is fully locked. The rebooted device displays the black window with the following ransom message:

You have Been Hacked, the ALL the Data the Encrypted, Key Contact For
