 Twitter is silent as of now. I think that there was some information about Petya last month.

I don't know of a new version of this ransomware from recently, but I believe the newest variant is not decryptable.

Petya Ransomware encrypts portions of the hard drive itself so victims are unable to access anything on the drive, including Windows. Mischa Ransomware was the newest variant of Petya that I am aware of...reported around May 2016. It will have the .cRh8 extension appended to the end of the encrypted data filename and leave files (ransom notes) named YOUR_FILES_ARE_ENCRYPTED.HTML, YOUR_FILES_ARE_ENCRYPTED.TXT.

Are there any obvious file extensions appended to or with your data files?

Did you find any ransom notes? These infections are created to alert victims that their data has been encrypted and demand a ransom payment. Check your documents folder for an image the malware typically uses for the background note. Check the C:\ProgramData (or C:\Documents and Settings\All Users\Application Data) for a randomly named .html, .txt, .png, .bmp, .url file. Most ransomware will also drop a ransom note in every directory/affected folder where data was encrypted.
