Blackheel – General Info

The Blackheel mean a ransomware-type infection. The virus comes from the HiddenTear ransomware family. Blackheel was elaborated particularly to encrypt all major file types. When the file is encrypted people are not able to use them. Blackheel adds the “.a” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by Blackheel, will be renamed into “myphoto.jpg.a“. As quickly as the encryption is completed, Blackheel places a special text file into every folder containing the encrypted data.

The message given by Blackheel text file requesting for the ransom is absolutely the like the statements given by other ransomware representatives belonging to the HiddenTear type. It literally mentions that the info is encrypted and that the only way to bring back it is to use a an unique decryption key. Sadly, this is absolutely true. The kind of cryptography mechanism used by Blackheel is still not correctly examined. Still, it is definitely certain that each victim might be given the specific decryption key, which is totally distinct. It is difficult to restore the files without the key available.

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

This is why paying the ransom generally does not provide any positive outcome and people simply waste their money for nothing.

We strongly 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 Blackheel ransomware and to recover the data data totally free.
