Decrypt Files Encrypted by Ransomware Viruses Part 4

And here we are again in 2017. With the rise of ransomware viruses, more and more malware researchers from EmsiSoft, Kaspersky, Avast and BleepingComputer join their efforts to create decryptors for those ransomware viruses who failed at being impenetrable. We have decided to sum up all the decryptable ransomware viurses so far with the hope they will be reachable to more people. Below, we have also linked the other parts of these series of articles.

Fake Cerber Ransomware

Being an imitator of one of the most notorious ransomware viruses ever to come out, the fake Cerber virus used the same wallpaper and even had a similar ransom note. It’s weakness however is that it was an EDA2 ransomware variant, which is not difficult to decrypt by researchers. Here is more information and decryption instructions:

The “.L0CKED” File Virus

Little was known about this ransomware initially, but this was because it was not very popular. Few days after being discovered it was deemed to be a part of the many ransomware variants in the EDA2 family. Decryption instructions below:

DeriaLock Ransomware

Being part of the Lockscreen type of ransomware viruses that deny access to the whole system, this virus was reverse engineered later on and a password for it was found. All you have to do is to follow these instructions to unlock your PC:

UltraDeCrypter 2016 Ransomware

This ransomware virus was rather big and massive in terms of the fuss it generated when it was released. It is one of the “nicest” ransom viruses out there that wish Merry Christmas to victims. Fortunatly, being a part of the Cryp1 and CryptXXX viruses this one was also decryptable, as a Christmas gift. Instructions and more info can be found below:

Globe v3 Ransomware

This virus is very interesting, primarily because it came out in so many variants, that researchers have lost count. The first of the updated Globe variants used the .decrypt2017 and .hnumkhotep extensions and the 3rd version of Globe was initially thought to be a major improvement. With time however, a decryptor was eventually developed for the virus, by well-recognized in this field TrendMicro researchers. Instructions, we have provided below:

Comrade Circle’s .encrypted4 File Virus Variant

The “communist propaganda” virus came out in a second iteration which was eventually decrypted. Interestingly enough, this virus offered users to become a part of the ransomware project, even promising them dividents. Well, I guess this is a failed affiliate campaign. Instructions for decryption can be found below:

Marlboro .oops Ransomware

This virus has been reported to be encrypting files with the .oops file extension. Fortunately for the users, the cyber-criminals have made an ‘.oops’ when creating the encryption code. Malware analysts from EmsiSoft have created a decryption tool that works with this ransomware without a hic up. Here is the web link for instructions:

Decrypt .Oops Files Encrypted by Marlboro Ransomware

Merry Christmas Ransomware

Also being a Trojan horse that steals the files on the computer, this virus used multiple file extensions – .PEGS1, .MRCR1, .RARE1 and RMCM1. Having an evil Santa and a bomb, this virus was surely intimidating. However, it was also decrypted and instructions can be found in the green box below:

Decrypt Files Encrypted by Merry Christmas Ransomware

Alcatraz Locker Ransomware

Encrypting the files with an added .Alcatraz file extension to them, this virus was also widespread until researchers from Avast shut it down fairly quickly, resulting in it’s successful decryption. Instructions can be located below:

How to Remove Decrypt from Windows.


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

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 Decrypt 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 Decrypt 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 Decrypt 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 Decrypt with SpyHunter Anti-Malware Tool

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


It is recommended to run a scan before purchasing the full version of the software to make sure that the current version of the malware can be detected by SpyHunter. Click on the corresponding links to check SpyHunter's EULA, Privacy Policy and Threat Assessment Criteria.

4. Click on the "Go" button again, but this time select Applications. Another way is with the ⇧+⌘+A buttons.


5. In the Applications menu, look for any suspicious app or an app with a name, similar or identical to Decrypt. If you find it, right-click on the app and select “Move to Trash”.


6: Select Accounts, after which click on the Login Items preference. Your Mac will then show you a list of items that start automatically when you log in. Look for any suspicious apps identical or similar to Decrypt. Check the app you want to stop from running automatically and then select on the Minus (“-“) icon to hide it.


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.
  • If all of the files are related, hold the ⌘+A buttons to select them and then drive them to “Trash”.

In case you cannot remove Decrypt via Step 1 above:

In case you cannot find the virus files and objects in your Applications or other places we have shown above, you can manually look for them in the Libraries of your Mac. But before doing this, please read the disclaimer below:

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 Decrypt. 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 Decrypt files from your Mac

When you are facing problems on your Mac as a result of unwanted scripts and programs such as Decrypt, 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 Decrypt on your Mac.

Ransomware for Mac Decrypt aims to encode all your files using an encryption algorithm which may be very difficult to decode, unless you pay money. This is why we have suggested a data recovery method that may help you go around direct decryption and try to restore your files, but only in some cases. Bear in mind that this method may not be 100% effective but may also help you a little or a lot in different situations.
