With the encryption process is finished, all encrypted files will now have a new extension appended to them. In every directory where there are encrypted files, Datahelp@iran.ir virus drops a file called ‘_readme.txt’. This file contains a ransom note that is written in the English. The ransom message directs victims to make payment in exchange for a key needed to unlock personal files.
