Remove Builder Virus (+Decrypt .builder files) – Hakbit Ransomware

Builder – General Info

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

The message given by Builder text file requesting for the ransom is absolutely the same as the statements given by other ransomware representatives belonging to the Hakbit family. It actually mentions that the info is encrypted which the only way to bring back it is to use a a distinct decryption key. Regretfully, this is absolutely true. The kind of cryptography mechanism applied by Builder is still not appropriately examined. Still, it is absolutely specific 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 Builder is that the victims cannot get to the key. The key is kept on a particular server run by the frauds related to Builder ransomware. To get the key and recover the important info people need to pay the ransom.

However, irrespective of the requested amount, people must keep away from paying the virus. Cyber frauds are not fair, so they tend to totally disregard what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom generally does not give any positive result 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 Builder ransomware and to recover the information data totally free. Hence, the just best decision is to recover the lost information from the available backup.
