Cryptre ransomware is a cryptovirus that demands $200 in Bitcoin for the alleged Decryption key 

Cryptre ransomware
Cryptre ransomware is a virus that was designed to extort money from victims. The main goal is to lock users' data and demand payment in cryptocurrency.
Cryptre ransomware is a cyber threat that encrypts your data and demands for payment because developers focus on money extortion. This is a version of CryptoWire ransomware that was discovered back in Spring of 2018. When your data gets encrypted, and the original code gets changed photos, videos, documents or music files get marked using the .encrypted extension. Cryptre virus then displays a program window with information about this process and the ransom demand. In Cryptre called window, virus developers explain what had happened and ask for a payment of $200. Hackers demand ransom and claim that when you pay, you can get your files restored. However, there is no guarantee that your files can be recovered and paying is not recommended.

Cryptre ransomware virus developers have already released the first variant of this ransomware dubbed CryptoWire virus that also marks encoded files with .encrypted extension and demands for the same $200 amount in Bitcoin. The ransom demand tactics are not much changed because after successful encryption the program window appears on the screen.

The message encouraging victims to pay up reads the following:

Your files has been safely encrypted

The only way you can recover your files is to buy a decryption key
The payment method is: Bitcoins. The price is: $200 = 0.06023569 Bitcoins

Click on the 'Buy decryption key' button.

Unfortunately, Cryptre ransomware attack starts with system changes, not the main encryption process. Ransomware firstly drops malicious files in various directories like:

  • %AppData%
  • %Local%
  • %LocalLow%
  • %Temp%
  • %Roaming%

Also, Cryptre ransomware changes Windows Registry Keys or adds new meanings. Malware is set to run various commands and disable certain system functions or programs like security features or antivirus software. These tactics make the threat more persistent and the AV detection[2] rate lower because some of the antivirus tools display falsely positive detection results.

Nevertheless, you can and need to remove Cryptre ransomware from the device as soon as possible so that no additional changes can be made. You should find a reputable anti-malware program and scan the machine entirely to delete all possible threats.
