What is China4444 ransomware? And how does it implement its attack?

China4444 ransomware is a file-encrypting virus created to encrypt important data in a computer. It is a new iteration of the 0x4444 ransomware which also happens to belong under the GlobeImposter ransomware group. There isn’t any major change in this new variant as with the other latest variants of GlobeImposter ransomware as this one still follows the same sequence in implementing its attack.

Once it implements its attack, it will drop a seemingly legitimate executable file named “svhost.exe” which is actually the malicious payload of China4444 ransomware. After that, it connects the infected computer to a remote server controlled by the attackers. In this remote server, it downloads other malicious components and places them on system folders. These malicious components are then used to make alterations in the Windows Registry so that China4444 ransomware can run on every system boot. Once these changes are applied, the search for files to encrypt begins. It usually targets common user-generated files such as documents, images, videos, audio, database, archives, and many more. Once it finds its targeted files, it encrypts them using a sophisticated encryption algorithm. Following file encryption, it appends the .RYK suffix to every compromised file and releases a file named “HOW_TO_BACK_FILES.txt” which contains the following content:

“YOUR FILES ARE ENCRYPTED !!!
