The alert stated by _readme.txt requesting the random os very comparable to the alerts given by other ransomware threats coming from the DJVU family. The caution generally shows that the data has been encrypted and the only option to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely true.
The method to encrypt the files used by Rumba is not completely looked into. Nevertheless, there is no doubt that each computer owner may be provided a special decryption key, which is definitely distinct. It is very difficult to recuperate the data without the proper type in place.
