Btc Virus – Details

The Btc stands for a ransomware-type infection. The virus comes from the Oled ransomware family. Btc was elaborated specifically to encrypt all major file types. Once the file is encrypted people are not able to use them. Btc adds the “.[markmontgomery2020@hotmail.com].btc” extension for each file encrypted by it.

Still, it is absolutely particular that each victim might be given the specific decryption key, which is totally unique. It is difficult to restore the files without the key available.

Another technique of Btc is that the victims cannot access to the key. The key is saved on a specific server run by the frauds connected with Btc ransomware. To get the key and recover the important info people need to pay the ransom.
