In this article, you will find more information about .amber files virus as well as a step-by-step guide on how to remove malicious files from an infected system and how to potentially recover files encrypted by this ransomware.

Ransomware dubbed .amber files virus has recently been spotted in the wild. It is a threat designed to interfere with essential computer settings in order to reach valuable files and encode them with the help of sophisticated cipher algorithm. Following encryption, it left targeted files renamed with the extension .amber. Information stored by corrupted files remains inaccessible. That’s why hackers drop a ransom note and extort a ransom payment.

.amber Files Virus – Distribution

It a common practice for hackers to spread ransomware like .amber via massive email spam campaigns. This method enables them to trick as many users as possible to run the ransomware payload on their devices. Emails that are part of infection campaigns often pose as representatives of legitimate websites, services, and even governmental institutions.

A few other traits could help you detect the presence of malicious code is received emails. The most common one is a file attachment of commonly used type like document, archive, image, PDF or other well-known file format. Once such a file is loaded on a target device, it triggers the malicious code that leads to infection with .amber ransomware.

Another malicious element that may appear in emails part of ransomware spread campaigns is URL address being it in the form of an in-text link, button, coupon, banner, image or other clickable form. The load of this URL address in your browser could result in the unnoticed execution of ransomware payload on the backgound.

.amber Files Virus – Overview

A ransomware dubbed .amber files virus has recently been spotted in the wild. As identified by security researchers, the threat belongs to the infamous ransomware family Dharma.

The infection process with .amber files virus begins when its payload file is started on the machine. This file contains various commands that navigate some of the initial infection stages. Since this file alone could not complete the attack to its very end, the ransomware creates several other malicious files and places them in the following folders:

  • %AppData%
  • %Local%
  • %LocalLow%
  • %Roaming%
  • %Temp%

By executing them in a strictly defined order, Dharma .amber becomes able to access some essential system components and interfere with their settings. These processes, in turn, enable it to evade detection until it finishes all infection stages.

One system component that is probably set as a target of this ransomware is the Registry Editor with its Run and RunOnce registry keys. This could be explained by the fact that these registry keys manage the automatic execution of all files listed under their directories:

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

So once .amber ransomware establishes malicious values there, it starts loading every next time you power on the infected system. By contaminating the registry key RunOnce, .amber files virus causes the automatic display of its ransom note. This usually happens at the end of the attack.

The purpose of this note is to extort a ransom payment for the recovery of encrypted files. At this point, the amount of the ransom is not stated. No matter how much the demanded ransom is, we advise you to avoid contacting hackers at the email they left – korvin0amber@cock.li. You should not pay them the ransom under any circumstances. There is no guarantee that they possess a working decrypter for your .amber files. Keep reading to find some alternative methods that are secure and may be useful as well.

.amber Files Virus – Encryption Process

Primarily, .amber files virus is a threat designed to find specific types of files so that it can transform parts of their code and leaves them out of order. This process is realized after a built-in encryption module is activated. This module scans the infected system for common files used for the store of important data. Among these files could be:

  • Audio files
  • Video files
  • Document files
  • Image files
  • Backup files
  • Banking credentials, etc

Each time the ransomware detects a target file, it applies sophisticated cipher algorithm that transforms the original code of the file. This process leaves all corrupted files inaccessible. Encrypted files could be recognized by the extension .amber that appears appended to their names.
