A1Lock Ransomware – Ways of Delivery

A1Lock ransomware might spread its infection via different ways. The payload file which executes the malicious script for this ransomware, that in turn infects your computer machine, is circling around the Internet. Samples of this ransomware have been found by a few different malware researchers. You can see the detections of some security vendors for one such sample embedded into an executable file by checking the image taken of the VirusTotal service below:

Also, the following domains are used to deliver that payload file:

Important Note! The above list with domains is for purely informational purposes and opening any domain is strongly advised against, because that will download the virus onto your computer system.

The A1Lock ransomware might be using other ways to deliver the payload file, such as social media and file-sharing sites. Freeware applications found on the Web could be promoted as helpful but also could hide the malicious script for this virus. Before opening any files after you have downloaded them, you should instead scan them with a security program. Especially if they come from suspicious places, such as emails or links. Also, don’t forget to check the size and signatures of such files for anything that seems out of place. You should read the ransomware prevention tips given in the forum.

A1Lock Ransomware – Technical Data

The A1Lock ransomware is a cryptovirus, which has been circulating with different variants. When the A1Lock ransomware encrypts your files, it will put the ..txt extension to every file and display a ransom note with payment instructions. The virus is a GlobeImposter variant.

The list with known versions for the A1Lock variant can be seen right down here:

  • Troy
  • .707
  • .490
  • .rose
  • .GOTHAM

The A1Lock ransomware can be set to make new registry entries in the Windows Registry to achieve a higher level of persistence. Such entries are usually designed in a way that will start the virus automatically with every launch of the Windows Operating System, such as the example shown right here below:

→“HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run”

The ransom message is placed inside a file called Read_ME.html. This is how it looks:

The ransom note states the following:

Your files are Encrypted!
For data recovery needs decryptor.
If you want to buy a decryptor, click the button:
Yes, I want to buy
Free decryption as guarantee.
Before paying you can send us 1 file for free decryption.
To send a message or file use this link.
( If you send a file for free decryption, also send file Read_ME.html )
Support
And finally, if you can not contact, follow these two steps:
1. Install the TOP Browser from this link:
torproject.org
2. Open this link in the TOP browser: support
Your personal ID:

If you click on the TOR link (https://n224ezvhg4sgyamb.onion.link), another page with further instructions will show up and you can see it here:

It states the following:

To buy the decryptor, you must pay the cost of: 0.29 Bitcoin ($997.19)
You have 2 days for payment
time left :
after finishing offer, decryptor cost will be 0.58 Bitcoin
You can buy bitcoin on one of these sites:

Requester*

Subject*

You should NOT under any circumstances pay the ransom or write to these criminals. Nobody can give you a guarantee that you will get your files decrypted upon payment, plus in that way you will support the crooks and probably motivate them to keep making ransomware or do similar criminal acts.

A1Lock Ransomware – Encryption Process

There is no official list with file extensions that the A1Lock ransomware seeks to encrypt and the article will be updated if such a list is discovered. However, all files which get encrypted will receive the ..txt extension appended to them. The virus doesn’t change or modify the original file name or extension of the encrypted files.

The encryption algorithm which is used for the virus is currently unknown, but the ransomware encrypts files, some of which have the following extensions:

→.doc, .docx, .xls, .xlsx, .jpg, .mp3, .pdf, .png, .txt

The A1Lock cryptovirus is reported by malware researchers to erase the Shadow Volume Copies from the Windows Operating System by executing the following command:

→vssadmin.exe delete shadows /all /Quiet

Executing the above-stated command will make the encryption process more effective, as one of the main ways for file recovery will be eliminated. Continue reading to find out what methods you can try out to potentially restore some of your files.

Remove A1Lock Ransomware and Restore ..txt Files

If your computer got infected with the A1Lock ransomware virus, you should have a bit of experience in removing malware. You should get rid of this ransomware as quickly as possible before it can have the chance to spread further and infect other computers. You should remove the ransomware and follow the step-by-step instructions guide provided below.

How to Remove A1Lock from Windows.


Step 1: Boot Your PC In Safe Mode to isolate and remove A1Lock

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 A1Lock 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 A1Lock 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 A1Lock 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 A1Lock with SpyHunter Anti-Malware Tool

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