What is BadRabbit Ransomware?

This new ransomware seems to be a variation of Petya with a similar lockout screen.   As of October 24, 2017, BadRabbit has hit Russia and Eastern Europe, but is expected to spread to other countries.  The attackers are asking the victim to pay a ransom in bitcoins to recover their files.  It will send the victim a message stating “their files are no longer accessible” and “no one will be able to recover them without our decryption service.”
