cursoDFIR Virus – Details

The cursoDFIR stands for a ransomware-type infection. cursoDFIR was elaborated particularly to encrypt all major file types. As soon as the file is encrypted people are unable to use them. cursoDFIR adds the “.cursoDFIR” extension for each file encrypted by it. For example, the file “myphoto.jpg“, as soon as encrypted by cursoDFIR, will be renamed into “myphoto.jpg.cursoDFIR“. As quickly as the encryption is completed, cursoDFIR places a special text file into every folder containing the encrypted data.

The message given by cursoDFIR text file requesting for the ransom is absolutely the like the statements given by other ransomware virus representatives. It literally discusses that the info is encrypted which the only way to bring back it is to use a an unique decryption key. Unfortunately, this is definitely true. The kind of cryptography mechanism used by cursoDFIR is still not correctly examined. Still, it is definitely certain that each victim may be given the specific decryption key, which is absolutely unique. It is difficult to bring back the files without the key available.

Another trick of cursoDFIR is that the victims cannot get to the key. The key is kept on a specific server run by the frauds associated with cursoDFIR ransomware. To get the key and recover the important info people need to pay the ransom.

However, regardless of the asked for amount, people need to stay away from paying the virus. Cyber frauds are unfair, so they tend to entirely disregard what their victims feel about the issue, even when the payment reaches their pockets. This is why paying the ransom usually does not provide any positive result and people just lose their money for absolutely nothing.

We highly advise that you do not contact these crooks and certainly do not transfer money into their accounts. It is said to admit that there are no utilities able to crack cursoDFIR ransomware and to recover the information data free of charge. Thus, the just best decision is to recover the lost data from the available backup.
