What is GANDCRAB V2.1 ransomware? And how does it execute its attack?

GANDCRAB V2.1 ransomware is a new version of the GandCrab v2 ransomware. This new variant uses the .CRAB extension in marking its encrypted files. Once the .js file of this crypto-virus is clicked, it will trigger a malicious JavaScript code. As a result, the malicious executable file of this ransomware is dropped into the system. The malicious executable file is placed under the %AppData% folder and is reported to have these parameters:
SHA256 hash:
9282ffd0f7aef39febc84f33a3090898e2fae6236cae7465a21ca58978d81b86
Size: 265,224 bytes
Location: %AppData%\RoamingiqB44.exe
Note that the malicious payload of this crypto-malware is also using other names. Meaning to say, it has random names but is generally placed in the very same directory. According to security experts, the malicious payload can be identified if you create a Windows Registry entry in this Windows sub-key – HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce. In this sub-key, you might see a value string which is named randomly and contains the actual name and location of the malicious executable file. After the malicious file is executed, GANDCRAB V2.1 ransomware might attempt to establish a connection with one of its hosts and servers.
During the encryption, this crypto-malware uses a sophisticated encryption algorithm that alters some portion of the file’s data – making it impossible for victims to open them. After that, it creates a file named “CRAB-DECRYPT.txt” that contains the following message:
“GANDCRAB v2.1
