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

OmniSphere ransomware is a ransomware threat discovered recently that uses a suffix of “.omnisphere” after it encodes a targeted file. This new crypto-malware does not belong to any infamous ransomware family as its source code does not have any snippets from other ransomware threats. It is developed either by an individual hacker or a criminal group.

The instant it infiltrates a computer, OmniSphere ransomware will drop its payload file in the system which will initiate a connection to a remote server. This payload file executes a series of commands to carry out its attack. Following its infiltration, OmniSphere ransomware will make changes in the Windows Registry, modifying some registry keys and entries in the process. This is done so that it can automatically run on every system boot. Aside from that, it also collects information from the infected computer using a data gathering module. The data obtained is used for another module called stealth protection which scans the system for any security programs and prevents them from interfering with the attack. After that, it starts encrypting its targeted files using the AES encryption algorithm. It mostly targets common user-generated files like documents, videos, images, audio files, databases, and many more. Once the encryption is completed, it appends the .omnisphere extension on the affected files and creates a file named “! DECRYPT_MY_FILES_OS.txt” to every folder that has encrypted files. This file contains the ransom note that states:

“## OmniSphere ransomware ##
