A new widespread ransomware attack is spreading like wildfire around Europe and has already affected over 200 major organizations, primarily in Russia, Ukraine, Turkey, and Germany, in the past few hours.
Dubbed "Bad Rabbit," is reportedly a new Petya-like targeted ransomware attack against corporate networks, demanding 0.05 bitcoin (~ $285) as ransom from victims to unlock their systems.
According to an initial analysis provided by the Kaspersky, the ransomware was distributed via drive-by download attacks, using fake Adobe Flash players installer to lure victims' in to install malware unwittingly.
"No exploits were used, so the victim would have to manually execute the malware dropper, which pretends to be an Adobe Flash installer. We’ve detected a number of compromised websites, all of which were news or media websites." Kaspersky Lab said.
However, security researchers at ESET have detected Bad Rabbit malware as 'Win32/Diskcoder.D' — a new variant of Petya ransomware, also known as Petrwrap, NotPetya, exPetr and GoldenEye.
Bad Rabbit ransomware uses DiskCryptor, an open source full drive encryption software, to encrypt files on infected computers with RSA 2048 keys.
ESET believes the new wave of ransomware attack is not using EternalBlue exploit — the leaked SMB vulnerability which was used by WannaCry and Petya ransomware to spread through networks.
Instead, it first scans an internal network for open SMB shares, tries a hardcoded list of commonly used credentials to drop malware, and also uses Mimikatz post-exploitation tool to extract credentials from the affected systems.
The ransom note, shown above, asks victims to log into a Tor onion website to make the payment, which displays a countdown of 40 hours before the price of decryption goes up.
The affected organizations include Russian news agencies Interfax and Fontanka, payment systems on the Kiev Metro, Odessa International Airport and the Ministry of Infrastructure of Ukraine.
Researchers are still analyzing Bad Rabbit ransomware to check if there is a way to decrypt computers without paying ransomware and how to stop it from spreading further.
