What is CrazyCrypt 4.1 ransomware? And how does it execute its attack?

CrazyCrypt 4.1 ransomware is a file-encrypting virus designed to hold files hostage by locking them and demand ransom from victims. This new ransomware threat uses a custom extension in marking the files it encrypts. At the time of writing, it isn’t clear if this crypto-virus is related to any ransomware group. Although it uses the same pattern in its attacks as other typical ransomware threats.

Once it infects a computer, CrazyCrypt 4.1 ransomware will drop its payload file in the system. This payload file is the one that connects the computer to a remote server controlled by the attackers. After establishing connection, it downloads its other components from the same remote server and places them to several system folders. These components are then used to carry out two modules for its attack namely, data harvesting module and stealth protection module. The former is the one that collects information from the computer and use them to generate a unique ID for the infected computer while the latter is used to bypass any security programs installed in the system that might interfere with the attack.

Moreover, CrazyCrypt 4.1 also modifies some entries in the Windows Registry in order to allow it to run automatically each time the computer is booted. Once it completes the system modification, it will scan the system for its targeted files like images, audio files, videos, documents, database, and many more. After finding these files, it encrypts them using a sophisticated cryptography and after the encryption, it appends a custom extension to every compromised file. It also opens a program window which contains its ransom note that states:

“All your files have been encrypted!
