What is Masok ransomware? And how does it implement its attack?
Masok ransomware is one of the latest variants of the Djvu/STOP ransomware group that’s been spotted in the month of August 2019. This new Djvu/STOP variant, like its predecessors, is designed to leave important data inaccessible by encrypting them using a sophisticated encryption algorithm. It was also discovered that Masok ransomware has the ability to install a Trojan type of infection which is known as “AZORult”. This kind of Trojan is designed to steal various account credentials. Thus, not only are your files at risk of getting corrupted, but your important credentials are also in danger of getting stolen.
Once it infiltrates a computer, it uses a built-in infection sequence which starts with a data-gathering process used to extract data classified into two namely, user personal data and attack optimization data. The acquired data is then used for another malicious process in order to bypass security programs installed in the computer.
In this process, Masok ransomware looks for signatures of antivirus programs, virtual machine hosts, and sandbox environments and once it finds programs with these signatures, their real-time engines are either shut down or removed. After that, it also alters the Windows Registry to allow it to run on every system boot. It then scans the computer for files that are mostly user-generated. Once the encryption is completed, it opens a text file named “_readme.txt” which contains the following content:
