Remove Banjo Virus (+Decrypt .[crysall.g@aol.com].banjo files) – Phobos Ransomware

Banjo Virus Ransomware

The Banjo stands for a ransomware-type infection. The infection comes from the Phobos ransomware family. Banjo was elaborated specifically to encrypt all major file types. Once the file is encrypted people are not able to use them. Banjo adds the “.[crysall.g@aol.com].banjo” extension for each file encrypted by it. For example, the file “myphoto.jpg“, when encrypted by Banjo, will be renamed into “myphoto.jpg.[crysall.g@aol.com].banjo“. As quickly as the encryption is finished, Banjo places a special text file into every folder containing the encrypted data.

The message given by Banjo text file requesting for the ransom is definitely the same as the statements given by other ransomware representatives coming from the Phobos family. It literally discusses that the info is encrypted and that the only way to bring back it is to use a a distinct decryption key. Unfortunately, this is definitely true. The sort of cryptography mechanism applied by Banjo is still not appropriately examined. Still, it is absolutely certain that each victim may be given the specific decryption key, which is completely distinct. It is difficult to restore the files without the key available.

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

However, regardless of the requested amount, people should 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 generally does not provide any positive result and people simply lose their money for nothing.

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