Decrypt Files Encrypted by Cerber Ransomware

cerber-decryption-how-to-sensorstechforum-mainFortunately, researchers at TrendMicro have successfully created a decryptor for Cerber ransomware. Unfortunately, the cyber-criminals have anticipated this move, immediately and mockingly enough releasing a second variant of this nasty cyber-threat. The war against Cerber continues, leaving many victims of this nasty malware string wherever it passes. For those who are unfamiliar, Cerber ransomware is a crypto-virus which uses an extremely strong encryption to encode the files, making them no longer readable. The virus then drops a ransom note scaring of users to pay the ransom. But do not become desperate, because a decryptor is now available for free and in this update we aim to show you how to use it to start decrypting files that have been encrypted by Cerber.

Cerber Ransomware – Background

When its initial variant came out, Cerber demanded affected users to pay the sum of 500 USD to decrypt their files. The sum was be paid in BitCoins, and the cryptovirus did not start out strongly and massively at its initial state. However, with new spam campaigns being released, Cerber quickly escalated and continued encrypting files with a strong AES encryption cipher and adding the .cerber file extension to them.

Users, being affected by this virus were advised to wait for a decryptor instead of funding the cyber-criminals. However, some users have paid the ransom and this “return of investment” gave the cyber-criminals who are most likely the same people, to create Cerber2 ransomware, that is at this state undecryptable.

Decrypting Files Encrypted by Cerber Effectively

To best display to you, the reader how to successfully decrypt your files for free, we need you to be focused while reading this and keep in mind that this process may take a lot of time, so be prepared.

We have divided this process into two stages:

Stage 1: Preparation

If you wish to decode data it all depends on factorizing the algorithm. This is why this process takes different time. Since this is usually so, you are obliged to leave your PC to work for a long time and not interrupt it in any way while it is decrypting files. Since these are the circumstances, you should be prepared for the situation by modifying your computer’s Power Options. Since most PC’s on Windows are usually configured to hibernate or sleep after some time, here is how to make them never to sleep again:

Step 1: Click on the battery icon in your system tray (next to the digital clock) in Windows and then click on More Power Options.
Step 2:The mighty Power options menu will appear. In your power plan click on Change Plan Settings.
Step 3: In your plan’s settings make sure you set “Turn off the display” and “Put computer to sleep” to “Never” from the drop down minutes menu.
Step 4: Click on “Change Advanced Plan Settings” and click to expand the “Hard Disk” option in the list there.
Step 5: From there, set the power settings (On Battery and Powered On) to “Never”.

Now, you should configure your PC to start decrypting Cerber ransomware’s files. Bear in mind that the process may take a lot of time so arm yourself with patience.

Stage 2: Decryption

Step 1: To begin decryption, download TrendMicro’s decrypter by clicking on the button below:

Step 1: Boot Your PC In Safe Mode to isolate and remove Cerber

OFFER

Manual Removal Usually Takes Time and You Risk Damaging Your Files If Not Careful!
We Recommend To Scan Your PC with SpyHunter

Keep in mind, that SpyHunter’s scanner is only for malware detection. If SpyHunter detects malware on your PC, you will need to purchase SpyHunter's malware removal tool to remove the malware threats. Read our SpyHunter 5 review. Click on the corresponding links to check SpyHunter's EULA, Privacy Policy and Threat Assessment Criteria

1. Hold Windows key() + R


2. The "Run" Window will appear. In it, type "msconfig" and click OK.


3. Go to the "Boot" tab. There select "Safe Boot" and then click "Apply" and "OK".
Tip: Make sure to reverse those changes by unticking Safe Boot after that, because your system will always boot in Safe Boot from now on.


4. When prompted, click on "Restart" to go into Safe Mode.


5. You can recognise Safe Mode by the words written on the corners of your screen.


Step 2: Uninstall Cerber and related software from Windows

Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:


1. Hold the Windows Logo Button and "R" on your keyboard. A Pop-up window will appear.


2. In the field type in "appwiz.cpl" and press ENTER.


3. This will open a window with all the programs installed on the PC. Select the program that you want to remove, and press "Uninstall"
Follow the instructions above and you will successfully uninstall most programs.


Step 3: Clean any registries, created by Cerber on your computer.

The usually targeted registries of Windows machines are the following:

  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

You can access them by opening the Windows registry editor and deleting any values, created by Cerber there. This can happen by following the steps underneath:

1. Open the Run Window again, type "regedit" and click OK.


2. When you open it, you can freely navigate to the Run and RunOnce keys, whose locations are shown above.


3. You can remove the value of the virus by right-clicking on it and removing it.
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.

IMPORTANT!
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.

Step 4: Scan for Cerber with SpyHunter Anti-Malware Tool

1. Click on the "Download" button to proceed to SpyHunter's download page.

7: Remove any left-over files that might be related to this threat manually by following the sub-steps below:

  • Go to Finder.
  • In the search bar type the name of the app that you want to remove.
  • Above the search bar change the two drop down menus to “System Files” and “Are Included” so that you can see all of the files associated with the application you want to remove. Bear in mind that some of the files may not be related to the app so be very careful which files you delete.

Disclaimer! If you are about to tamper with Library files on Mac, be sure to know the name of the virus file, because if you delete the wrong file, it may cause irreversible damage to your MacOS. Continue on your own responsibility!

1: Click on "Go" and Then "Go to Folder" as shown underneath:

2: Type in "/Library/LauchAgents/" and click Ok:

3: Delete all of the virus files that have similar or the same name as Cerber. If you believe there is no such file, do not delete anything.

You can repeat the same procedure with the following other Library directories:

→ ~/Library/LaunchAgents
/Library/LaunchDaemons

Tip: ~ is there on purpose, because it leads to more LaunchAgents.


Step 2: Scan for and remove Cerber files from your Mac

When you are facing problems on your Mac as a result of unwanted scripts and programs such as Cerber, the recommended way of eliminating the threat is by using an anti-malware program. Combo Cleaner offers advanced security features along with other modules that will improve your Mac’s security and protect it in the future.


Step 3 (Optional): Try to Restore Files Encrypted by Cerber on your Mac.

Ransomware for Mac Cerber aims to encode all your files using an encryption algorithm which may be very difficult to decode, unless you pay money.

      Hello and thank you for the feedback! We do not have control over third-party web links, as you may have guessed and sometimes the third-party site admins may decide to change the URL, which may have been the case here. I have updated the Download button with a URL to the decrypter. The URL is the following:
