BigBossHorse Virus Ransomware

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

The message given by BigBossHorse text file requesting the ransom is definitely the same as the statements given by other ransomware representatives belonging to the GarrantyDecrypt family. It literally mentions that the info is encrypted which the only way to bring back it is to use a a distinct decryption key. Unfortunately, this is absolutely true. The type of cryptography mechanism used by BigBossHorse is still not correctly examined. Still, it is definitely certain that each victim may be given the specific decryption key, which is totally unique. It is difficult to restore the files without the key available.

Another trick of BigBossHorse is that the victims cannot access to the key. The key is saved on a specific server run by the frauds related to BigBossHorse ransomware. To get the key and recover the important info people have to pay the ransom.

However, irrespective of the asked for quantity, people should keep away from paying the ransom virus. Cyber frauds are unfair, so they tend to completely ignore what their victims feel about the problem, 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 strongly encourage 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 BigBossHorse ransomware and to recover the information data for free. Thus, the only best decision is to recover the lost data from the available backup.
