Isolated Virus Removal Guide (+Decode .isolated files) – Crypto Locker Ransomware

Crypto Locker – Ransomware

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

The message given by Isolated text file requesting the ransom is absolutely the same as the statements given by other ransomware virus representatives belonging to the Crypto Locker family. It actually mentions that the info is encrypted and that the only way to restore it is to use a a distinct decryption key. Sadly, this is absolutely true. The sort of cryptography mechanism used by Isolated is still not correctly examined. Still, it is absolutely specific that each victim might be given the specific decryption key, which is completely distinct. It is difficult to restore the files without the key available.

Another trick of “Crypto Locker” is that the victims cannot access to the key. The key is kept on a specific server run by the frauds related to Isolated ransomware. To get the key and recover the important info people need to pay the ransom, which totals up to $100. To get the payment details users are advised to contact the frauds through email or telegram. The alert also suggests that the users need to contact the Isolated developers within 72 hours after the files encryption happened. The message says that doing so users will get a 50% discount, so the ransom quantity will drop down to $50.

However, irrespective of the requested quantity, people need to keep away from paying the ransom virus. Cyber frauds are not fair, so they tend to completely disregard what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom typically does not provide any positive result and people just waste their money for nothing.

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