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.

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

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.
