Ehiz Virus Ransomware

Ehiz is a destructive software functioning as common ransomware. Michael Gillespie, the widely known virus researcher, very first discovered this new name in the DJVU ransomware family.

Ehiz was developed for the sole purpose to encrypt all popular file types. Logically, as soon as the file encryption is effectively achieved, the users are unable to get access to them. Ehiz virus adds its own “.ehiz” to all the encrypted data. For instance, the file “price_list.xls”, when modified by Ehiz, will be titled as “price_list.xls.ehiz”. When the encryption is achieved, Ehiz puts its own distinct text file (_readme.txt) into all the folders that keep the encrypted files.

The message mentioned by text file requesting the random os very similar to the notifications given by other ransomware dangers belonging to the DJVU family. The caution essentially shows that the data has been encrypted and the only solution to get access to it is to use a distinct standalone key. Regretfully, this statement is absolutely real.

The method to secure the files used by Ehiz is not totally investigated. However, there is no doubt that each computer owner may be provided a special decryption key, which is absolutely unique. It is extremely tough to recover the information without the suitable key in place.

“Don’t worry, you can return all your files!”, from _readme.txt message:

Don't worry, you can return all your files! virus

One more peculiarity of the Ehiz ransomware is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the complete control by the crooks who have introduced the Ehiz infection into the web. In order to get the key and bring back the crucial information, the users are told to get in touch with the frauds by means of email or by telegram and to pay the ransom in the quantity of $980.

The message also states that individuals must contact the Ehiz authors within 72 hours upon the moment of the information encryption. The alert shows that by doing so the people will obtain a 50% discount, therefore, the ransom amount drops down to $490.

No matter what the quantity of the ransom is, we strongly recommend that you do not pay the ransom. There is no warranty that these online crooks will keep their guarantees, so they might not care at all what the victims feel about the encryption, even when the amount of the ransom is gotten into their accounts. Thus, paying ransom often does not lead to an effective recovery. So, the users might merely lose their money for nothing.

Similarly, we prompt you not to call the frauds as they instruct. Do not transfer money into their wallets. There are no applications that might split the Ehiz virus or bring back the information at no cost. For that reason, the only correct decision is to bring back the data from possible backups (if available).
