BadRabbit is self-propagating and has many similarities to the June 2017 Petya / NotPetya outbreak.
A new strain of ransomware called BadRabbit (Ransom.BadRabbit) began spreading yesterday, October 24, 2017, with the vast majority of infection attempts seen in Russia. However, because BadRabbit is self-propagating, and can spread across corporate networks, organizations should remain particularly vigilant.
