Remove OmniSphere Ransomware Virus (Free Guide)
OmniSphere ransomware hits your files for ransom
Contents
OmniSphere ransomware is a malicious virus that encrypts files on a computer only to demand a ransom. It has been first noticed on September 30, 2019. The malicious program appends .omnisphere file extensions to encoded files and then creates a !DECRYPT_MY_FILE_OS.txt and unique_decrypt.key files in every folder containing corrupted data.
There is no surprise that the ransom note contains instructions on how to contact and pay cyber criminals to get locked data back. The criminals suggest buying an OmniSphere decryptor from them. The .txt file instructs to download Tor browser and open a provided URL. Once the victim does that, one needs to upload the second file created by ransomware – unique_decrypt.key.
It is important to understand that the encryption method used by ransomware is a process that cannot be reversed without a private key (long set of symbols), which only the attackers have.
However, we do NOT encourage you to pay the ransom as you might never receive OmniSphere decryptor. Cyber criminals use crypto-viruses to extort money – they do not care about their victims at all.
Full contents of the ransom note (!DECRYPT_MY_FILE_OS.txt):

Crypto-malware proliferation techniques
File-encrypting viruses like OmniSphere, Sodinokibi, Nesa or BOOT tend to attack victims in an obfuscated form. Typically, such malware never arrives in a form of an .exe file; it comes in a form of a safe-looking document, for instance, Word or PDF. Then various deceptive techniques are used to make the victim activate the virus. For example, clicking enable editing of file or macro commands can trigger a consequence of events which will launch and run the ransomware.
To prevent ransomware attacks, you must be very attentive and stay away from untrustworthy emails, websites and downloads. You must remember that nothing is free and if you decided to find a software crack online, know that cyber criminals use them as a bait to push malware to your computer. It is a very popular method to serve viruses to unaware users.
Remove OmniSphere virus and recover your data
OmniSphere ransomware removal should be carried out with a help of professional and up-to-date antivirus. While we do not suggest any particular antivirus, you should try updating the one you have and running a system scan. If you do not have one yet, consider installing one. There are many great both free and paid options to choose from.
However, before you run that antivirus, you need to read the instructions we provided below the post for a successful virus elimination.
As soon as you remove OmniSphere virus, you can start recovering your files from a backup. The malware described in this article is relatively new, so currently there are no updates regarding its decryption tools. We’ll update the article as soon as new information surfaces.
