Once the encryption is accomplished, Wwza puts its own distinct text file (_readme.txt) into all the folders that store the encrypted files.
The message stated by document asking for the random os very similar to the alerts offered by other ransomware risks coming from the DJVU family. The caution generally shows that the data has been secured and the only service to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely true.
