This ransomware seems to be a variant of Petya and even has a similar aesthetic of the lockout screen. Bad Rabbit assures the victim they can recover their files if they pay a ransom of .05 bitcoins in a narrow window of time. Victims are then directed to a darknet hidden service (.onion address). So victims will be required to download the TOR browser or OrFox mobile browser in order to access the .onion address.

Once the address is reached users are required to enter in a personal assigned key. If validated a bitcoin account is provided to them to transfer the money to. If the victim fails to make a payment in the allotted time the price increases. At the time of this writing, the starting price .05 bitcoins (BTC) translates to $275.59 USD.
