Hoop was developed for the sole purpose to encrypt all popular file types. Realistically, as soon as the file encryption is effectively accomplished, the users are not able to get access to them. Hoop virus includes its own “.hoop” to all the encrypted data. For example, the file “price_list.xls”, as soon as modified by Hoop, will be titled as “price_list.xls.hoop”. As soon as the file encryption is achieved, Hoop puts its own special text document (_readme.txt) into all the folders that save the encrypted files.
The message stated by text file asking for the random os really similar to the alerts given by other ransomware threats coming from the DJVU family. The caution essentially shows that the information has been secured and the only solution to get access to it is to use a special standalone key. Regretfully, this statement is definitely real.
The technique to encrypt the files used by Hoop is not entirely researched. However, there is no doubt that each computer system owner might be provided an unique decryption key, which is absolutely special. It is incredibly hard to recuperate the data without the appropriate key in place.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Hoop infection is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the total control by the scoundrels who have released the Hoop infection into the web. In order to obtain the key and bring back the important data, the users are informed to get in touch with the scams via e-mail or by telegram and to pay the ransom in the amount of $980.
