Moia is a malicious software functioning as common ransomware. Michael Gillespie, the widely known virus researcher, very first discovered this new name in the DJVU ransomware family.

Moia was developed for the sole function to encrypt all popular file types. Realistically, as soon as the file encryption is effectively accomplished, the users are not able to get access to them. Moia ransomware includes its own “.moia” to all the encrypted data. For instance, the file “price_list.xls”, as soon as crypted by Moia, will be entitled as “price_list.xls.moia”. When the file encryption is achieved, Moia puts its own unique text document (_readme.txt) into all the folders that store the encrypted files.

The alert mentioned by _readme.txt asking for the random os extremely comparable to the notices provided by other ransomware dangers coming from the DJVU family. The warning generally indicates that the information has been encrypted and the only service to get access to it is to use a distinct standalone key. Regretfully, this declaration is absolutely true.

The approach to secure the files used by Moia is not entirely researched. Nevertheless, there is no doubt that each computer system owner might be provided an unique decryption key, which is absolutely distinct. It is extremely tough to recuperate the data without the proper key in location.
