What is Bk666 ransomware? And how does it carry out its attack?

Bk666 Ransomware

Bk666 ransomware is a new variant of Dharma ransomware that’s created to lock important data in a targeted computer. This new Dharma variant uses a “.bk666” extension in marking the files it encrypts, hence the name. Once this crypto-malware obtains access to a targeted machine, they will install Bk666 ransomware in the system. After that, it will start to make changes in the system in order to carry out its attack. It may modify some registry keys and entries in the Windows Registry allowing it to run automatically on every system boot. It then scans the computer for its targeted files and encrypts them using a sophisticated encryption algorithm. After the encryption, it appends the .bk666 extension to each one of the affected files and opens a program window that contains the following ransom note:
