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

Norvas ransomware is a data-encrypting virus created to encode important files in a computer, leaving them inaccessible to users. It is one of the latest variants of Djvu ransomware which belongs under the STOP ransomware family. It appends a “.norvas” extension to the compromised files and demands $980 ransom from its victims. There is little to nothing alterations made in this new variant as it still follows the same pattern in carrying out its attack as with other variants of Djvu ransomware.
Once it infects a computer, it drops its malicious payload in the system and connects it to a Command and Control server where it downloads several malicious components and places them to system folders. It may also make entries in the Windows Registry and modifies existing ones so that it can automatically run on each time users starts their computers. It uses a data harvesting module to collect information from the system as well as a stealth protection module which avoids detection from any security programs.
After it completes modifying the compromised system, Norvas ransomware will encrypt its targeted files using both the AES and RSA 1024 ciphers. Following data encryption, Norvas ransomware appends the .Norvas extension to every affected file and releases its ransom note that’s either named “_readme.txt” which states:
“ATTENTION!
