Ygvb – Ransomware
Ygvb is a malicious software working as common ransomware. Michael Gillespie, the widely known malware researcher, first discovered this new name in the DJVU ransomware family.
Ygvb was created for the sole purpose to encrypt all popular file types. Logically, as soon as the file encryption is effectively accomplished, the users are unable to get access to them. Ygvb ransomware includes its own “.ygvb” to all the encrypted data. For example, the file “price_list.xls”, when crypted by Ygvb, will be entitled as “price_list.xls.ygvb”. Once the file encryption is accomplished, Ygvb puts its own special text document (_readme.txt) into all the folders that save the encrypted files.
The message mentioned by text file requesting the random os very comparable to the alerts provided by other ransomware hazards belonging to the DJVU family. The caution basically indicates that the files have been secured and the only option to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely real.
The technique to encrypt the files used by Ygvb is not completely looked into. However, there is no doubt that each computer system owner might be issued a special decryption key, which is absolutely special. It is very difficult to recuperate the data without the proper key in place.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Ygvb infection is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the total control by the criminals who have actually released the Ygvb ransomware into the world wide web. In order to obtain the key and restore the crucial data, the users are informed to connect with the frauds via e-mail or by telegram and to pay the ransom in the quantity of $980.
The message likewise says that the people must contact the Ygvb authors within 72 hours upon the minute of the information file encryption. The alert indicates that by doing so the people will obtain a 50% discount, for that reason, the ransom quantity drops down to $490.
