Isos – General Info

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

The message given by Isos text file requesting the ransom is definitely the same as the statements given by other ransomware virus representatives coming from the Phobos clan. It actually discusses that the info is encrypted which the only way to restore it is to use a a special decryption key. Unfortunately, this is absolutely true. The type of cryptography mechanism used by Isos is still not appropriately examined. Still, it is absolutely specific that each victim might be given the specific decryption key, which is absolutely distinct. It is impossible to restore the files without the key available.

Another trick of Isos is that the victims cannot get to the key. The key is saved on a particular server run by the frauds associated with Isos ransomware. To get the key and recover the important information people have to pay the ransom.

Nonetheless, irrespective of the asked for quantity, people should stay away from paying the ransom virus. Cyber frauds are unfair, so they tend to entirely 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 waste their money for absolutely nothing.

We strongly encourage 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 Isos ransomware and to recover the data data totally free. Therefore, the only best decision is to recover the lost information from the available backup.
