Questions about Pdff ransomware

Pdff ransomware is a cryptovirus that was first spotted on January the 10th affecting Middle East computer users. The malware is a variant of STOP ransomware and Djvu ransomware viruses which have been using AES[1] encryption algorithm to lock up data by appending .pdff file extension to each of the affected files. For example, a picture.jpg is turned into picture.jpg.pdff, and becomes inaccessible. .Pdff files virus then drops a ransom note _openme.txt  into each of the affected folders which explains victims that they have to contact crooks via pdfhelp@india.com or pdfhelp@firemail.cc and pay ransom in Bitcoin in order to retrieve the decryptor that is stored on a remote server by hackers. Allegedly, criminals offer 50% discount if the user contacts them within the first 72 hours. Unfortunately, the ransomware is not decryptable yet, and users will have to use alternative methods when trying to recover their data.
