Udla – Ransomware
Udla is a malicious software functioning as common ransomware. Michael Gillespie, the well-known virus researcher, very first discovered this new name in the DJVU ransomware family.
Udla was developed for the sole purpose to encrypt all popular file types. Realistically, as quickly as the file encryption is successfully accomplished, the users are not able to get access to them. Udla virus includes its own “.udla” to all the encrypted data. For instance, the file “price_list.xls”, once modified by Udla, will be entitled as “price_list.xls.udla”. When the file encryption is achieved, Udla puts its own distinct text document (_readme.txt) into all the folders that keep the encrypted files.
The alert mentioned by text file asking for the random os very comparable to the notices given by other ransomware threats belonging to the DJVU family. The warning basically shows that the information has been secured and the only option to get access to it is to use a distinct standalone key. Regretfully, this declaration is absolutely real.
The approach to encrypt the files used by Udla is not entirely researched. However, there is no doubt that each computer system owner may be issued a special decryption key, which is definitely special. It is extremely difficult to recuperate the information without the suitable type in location.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Udla infection is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the complete control by the scoundrels who have released the Udla infection into the internet. In order to obtain the key and bring back the important data, the users are told to contact the scams via e-mail or by telegram and to pay the ransom in the amount of $980.
The message likewise states that the people need to call the Udla authors within 72 hours upon the minute of the information file encryption. The alert indicates that by doing so individuals will get a 50% discount rate, for that reason, the ransom quantity falls to $490.
No matter what the quantity of the ransom is, we highly encourage that you do not pay the ransom. There is no warranty that these online crooks will keep their guarantees, so they may not care at all what the victims feel about the file encryption, even when the quantity of the ransom is gotten into their accounts. For this reason, paying ransom typically does not lead to an effective healing. So, the users might just lose their money for absolutely nothing.

There are no applications that might break the Udla ransomware or bring back the information at no charge. Therefore, the only appropriate decision is to bring back the information from possible backups (if available).
