Cognizant Maze Ransomware

Cognizant Maze Ransomware is a Windows virus that secretly launches a data-encryption process inside the computer and locks the files stored there. Once Cognizant Maze Ransomware encrypts all important files on the victims’ PC, it then proceeds to demand a money payment in order to unlock the files.

Cognizant Maze Ransomware note

The threats of the Ransomware category are very widespread at the moment and getting one in your computer could result in severe data loss, which could be especially problematic and damaging if any of the files that the virus encrypts have been highly important to you. There is a preventative measure that can neutralize the effects of a potential Ransomware attack and that measure is the creation of a backup, where you store copies of your most valuable data files. Since the backup location isn’t connected to the computer, the Ransomware that may attack you won’t be able to reach the files stored on it. However, most users don’t have the habit of regularly backing up their important files which is why threats such as Cognizant Maze Ransomware are so effective. Once the cryptovirus locks a given file, the only thing that can guarantee that you can open this file again is the corresponding decryption key. However, getting this key requires you to pay a ransom to the hackers who are behind the Ransomware and if that’s not bad enough, what makes matters even worse is the fact that you can’t really trust the criminals that are blackmailing you. The hackers behind Cognizant Maze Ransomware may or may not send you a working access key for your files after you’ve completed the money transaction. That is why we don’t advise you to go for this option as it may simply worsen the situation instead of improving it.

The Cognizant Maze Ransomware Attack

The Cognizant Maze Ransomware attack is a new Ransomware threat for Windows systems that deprives users of access to their important files. The Cognizant Maze Ransomware attack achieves this through the use of a sophisticated encryption algorithm that keeps the files sealed until the decryption key is applied.

Unfortunately, the complex encryption algorithms used by newer Ransomware versions like Cognizant Maze Ransomware make recovering the files without the corresponding access key very difficult and not always possible. This, to a large extent, determines the high effectiveness of these viruses as a lot of users who really need their files back are forced to pay the demanded ransom. However, as we said, this isn’t really the wisest thing you could do, which is why we’ve tried to offer you some potential alternatives.

This is one of the main things preventing your software from accessing the locked files. The extension can’t be removed manually and you will need to decrypt the files in order to rid your files of it. In the next lines, you will see removal instructions for Cognizant Maze Ransomware and, after that, you will find some alternative data-recovery options. We strongly advise you to follow all of the instructions from the guide as doing so may help you deal with the Ransomware and potentially restore some of the sealed data without needing to interact with the criminals behind Cognizant Maze Ransomware.

Some of the steps will likely require you to exit the page. Bookmark it for later reference.

Reboot in Safe Mode (use this guide if you don’t know how to do it).



We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab. Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

Drag and Drop Files Here to Scan
Maximum file size: 128MB.

This scanner is free and will always remain free for our website's users. You can find its full-page version at:

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections.


Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

hosts_opt (1)

If there are suspicious IPs below “Localhost” – write to us in the comments.

Type msconfig in the search field and hit enter. A window will pop-up:


Go in Startup —> Uncheck entries that have “Unknown” as Manufacturer.

  • Please note that ransomware may even include a fake Manufacturer name to its process. Make sure you check out every process here is legitimate.


To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
a professional malware removal tool.

Type Regedit in the windows search field and press EnterOnce inside, press CTRL and F together and type the virus’s Name. 

Search for the ransomware  in your registries and delete the entries. Be extremely careful –  you can damage your system if you delete entries not related to the ransomware.

Type each of the following in the Windows Search Field:

  1. %AppData%
  2. %LocalAppData%
  3. %ProgramData%
  4. %WinDir%
  5. %Temp%

Delete everything in Temp. The rest just check out for anything recently added. Remember to leave us a comment if you run into any trouble!
