What is Boot ransomware? And how does it implement its attack?
Boot ransomware is a data-encrypting virus designed to corrupt files in an infected computer. It is a new variant of Djvu ransomware. According to researchers, this new Djvu ransomware might bring the “AZORult” Trojan horse on the infected computer. This means that it is not your typical Djvu variant. It uses a “.boot” extension in marking the files it compromise. It seems to implement its attack in the same manner as other variants of Djvu by running a payload file in the system.
Once the malicious payload of this ransomware is downloaded and installed in the system, Boot ransomware will start to execute its attack by downloading more malicious files as well as create new ones. It also modifies some Windows system files and even the Windows Registry to so it can achieve persistence. After that, it scans the system looking for certain files to encrypt. During the encryption, it uses both the AES and RSA encryption algorithms. Once it’s done locking the targeted data, it will mark them with the .boot suffix. Moreover, a file named “_readme.txt” is released which contains the following context:
Don’t worry, you can return all your files!
