Zida – General Info
Zida is a destructive software application working as typical ransomware. Michael Gillespie, the widely known malware researcher, very first found this new name in the DJVU ransomware family.
Zida was created for the sole purpose to encrypt all popular file types. Rationally, as quickly as the file encryption is effectively achieved, the users are not able to get access to them. Zida ransomware includes its own “.zida” to all the encrypted data. For example, the file “price_list.xls”, as soon as crypted by Zida, will be entitled as “price_list.xls.zida”. As soon as the file encryption is accomplished, Zida puts its own special text document (_readme.txt) into all the folders that keep the encrypted files.
The alert stated by document asking for the random os extremely similar to the alerts provided by other ransomware risks coming from the DJVU family. The caution essentially shows that the files have been secured and the only option to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely real.
The method to secure the files used by Zida is not entirely researched. However, there is no doubt that each computer system owner may be provided an unique decryption key, which is definitely unique. It is exceptionally hard to recuperate the information without the proper key in location.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Zida infection is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the complete control by the crooks who have introduced the Zida ransomware into the internet. In order to obtain the key and bring back the crucial information, the users are told to connect with the frauds through e-mail or by telegram and to pay the ransom in the amount of $980.
The message likewise says that the people should contact the Zida authors within 72 hours upon the moment of the data encryption. The alert suggests that by doing so individuals will obtain a 50% discount, for that reason, the ransom quantity falls to $490.
No matter what the quantity of the ransom is, we highly recommend that you do not pay the ransom. There is no assurance that these online criminals will keep their pledges, so they may not care at all what the victims feel about the encryption, even when the quantity of the ransom is received into their accounts. Hence, paying ransom typically does not result in an effective healing. So, the users may just lose their money for absolutely nothing.
Similarly, we urge you not to call the scams as they advise. Do not transfer cash into their wallets. There are no applications that might split the Zida virus or bring back the data at no charge. Therefore, the only correct decision is to bring back the information from possible backups (if readily available).
