What is Pendor ransomware?

Pendor ransomware is a new malicious-encrypting threat discovered by MalwareHunterTeam. This ransomware demands $50 in exchange for the decryption key. It encodes .pnr extension on each targeted data, for instance, from image.jpg it now becomes image.jpg.pnr and then sets a red circle accompanied by an “x” symbol as the icon that represents the encrypted files. Following its encryption, Pendor creates malicious files like pendor.exe and READ_THIS_FILE_1.txt and places them on the desktop. Both of these files contains the same ransom message such as follows:
Nobody can recover your files without our decryption service.
We guarantee that you can recover all your files.
All you need to do is submit the payment and purchase the decryption key.
