YAYA – General Info
The YAYA stands for a ransomware-type infection. The virus comes from the GlobeImposter ransomware family. YAYA was elaborated particularly to encrypt all major file types. When the file is encrypted people are not able to use them. YAYA adds the “.YAYA” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by YAYA, will be renamed into “myphoto.jpg.YAYA“. As soon as the encryption is completed, YAYA places a special text file into every folder containing the encrypted data.The message given by YAYA text file requesting for the ransom is definitely the same as the statements given by other ransomware virus representatives coming from the GlobeImposter family. It literally mentions that the info is encrypted which the only way to bring back it is to use a a distinct decryption key. Sadly, this is definitely true. The sort of cryptography mechanism used by YAYA is still not appropriately examined. Still, it is absolutely particular that each victim might be given the specific decryption key, which is totally unique. It is impossible to bring back the files without the key available.
Another technique of YAYA is that the victims cannot get to the key. The key is stored on a particular server run by the frauds connected with YAYA ransomware. To get the key and recover the important information people have to pay the ransom.
YAYA encrypted your documents, but that might not be the only damage done to you. The ransomware might still be hidingon your computer. To identify whether this holds true, we suggest downloading GridinSoft Anti-Malware.

Therefore, the only best decision is to recover the lost information from the available backup.
