Dapo Virus – Details

Dapo is a malicious software working as typical ransomware. Michael Gillespie, the popular virus researcher, first found this new name in the DJVU ransomware family.

Dapo was developed for the sole purpose to encrypt all popular file types. Rationally, as quickly as the file encryption is successfully accomplished, the users are unable to get access to them. Dapo virus adds its own “.dapo” to all the encrypted files. For example, the file “price_list.xls”, as soon as crypted by Dapo, will be entitled as “price_list.xls.dapo”. When the encryption is accomplished, Dapo puts its own unique text document (_readme.txt) into all the folders that save the encrypted files.

The message mentioned by _readme.txt asking for the random os very similar to the alerts offered by other ransomware threats belonging to the DJVU family. The caution generally shows that the files have been secured and the only option to get access to it is to use a distinct standalone key. Regretfully, this declaration is definitely true.

The technique to secure the files utilized by Dapo is not entirely researched. However, there is no doubt that each computer owner might be provided an unique decryption key, which is definitely distinct. It is very tough to recover 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 Dapo 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 total control by the crooks who have launched the Dapo ransomware into the world wide web. In order to get the key and restore the important data, the users are informed to contact the scams by means of email or by telegram and to pay the ransom in the quantity of $980.

The message likewise says that individuals should call the Dapo authors within 72 hours upon the minute of the information encryption. The alert shows that by doing so the people will obtain a 50% discount, therefore, the ransom amount falls to $490.

There are no applications that might crack the Dapo ransomware or restore the data at no charge. For that reason, the only appropriate choice is to restore the data from possible backups (if available).
