In this article, you will find more information about .crypt2019 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.

The so-called .crypto2019 files virus is a data locker ransomware that belongs to Scarab threat family. Once it manages to run malicious files on your device, it interferes with essential system settings contamination of which enables it to encode valuable files. Following encryption, .crypt2019 requires a ransom payment for files decryption.

.crypt2019 Files Virus – Distribution

There are several spread techniques that may be used for the distribution of .crypt2019 ransomware. One of those techniques is called malwspam. It lets hackers spread malicious code via massive email campaigns. They usually embed their malware in files of common types and attach these files to email messages. In addition, emails are often disguised as legitimate businesses or services.

The last could be explained by the fact that their purpose is to trick you into opening the corrupted file as this action will trigger the ransomware payload on your device. A variety of common file types such as documents, PDFs, images could be misused for the spread of .crypt2019 ransomware payload.

These files are often presented as:

  • Invoices coming from reputable sites, like PayPal, eBay, etc.
  • Documents from that appear to be sent from your bank.
  • An online order confirmation note.
  • Receipt for a purchase.
  • Others.

Malware authors may bet on compromised software installers and infected websites for their attack campaigns. These methods enable them to embed the ransomware payload to an app installer or inject it into a web page. Both cases could result in automatic and unnoticed execution of this payload directly on a target system.

.crypt2019 Files Virus – Overview

Security researchers identified that .crypto2019 files virus is a strain of the vicious ransomware family

Scarab. The name of this threat is a derivative of the extension it appends to each file it corrupts. The infection process with .crypt2019 cryptovirus begins when its payload is loaded on your computer system. Afterward, the threat attempts to complete a long sequence of malicious activities.

At first, it is likely to create more malicious files and objects by positioning them in some of the following folders:

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

Once the ransomware establishes all needed files it continues with the completion of following infection stages. Passing through these stages .crypt2019 gains persistence while remaining invisible to active security measures. This could be explained by the fact that this threat has a complex code designed to access essential system components. Furthermore, it could apply various changes to the settings of these components which eventually enable the ransomware to misuse their functionalities for malicious purposes.

An affected system component is likely to be the Windows Registry. Since it is a hierarchical database that stores low-level settings for the operating system and for some applications, cryptoviruses like .crypt2019 are often set to misuse certain functionalities. By adding its malicious values under registry keys like Run and RunOnce, .crypt2019 becomes able to load automatically along with all essential system processes on each system start and to display a ransom message at the end of the attack.

This message attempts to trick you into transferring a ransom fee to hackers. Although they promise to send back an efficient decryption tool for .crypt2019 files, we recommend you to avoid paying them the ransom. There is no guarantee if their tool will be able to decrypt encoded files or leave them broken. Furthermore, even if you pay the ransom you could never receive any answer from them.

.crypt2019 Files Virus – Encryption Process

After the contamination of all system components that support the attack, .crypt2019 files virus activates a built-in cipher module to scan system drives for target files. What’s coming next is the corruption of all detected target files with the help of sophisticated cipher algorithm. Like previous versions of Scarab ransomware, .crypt2019 is probably designed to use the AES cipher algorithm to encode data. During this infection stage, all your valuable files could be transformed in a way that will prevent you from accessing data they store:

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

Following encryption, all corrupted files will appear with the extension .crypt2019 at the end of their names.
