GandCrab v5.1.4 Ransomware – Infection Overview

An infection with this version of GandCrab ransomware begins with the execution of its payload on your system. Since the attack could not be realized with the help of only one file, GandCrab v5.1.4 needs to establish additional malicious files on it. Some of these files may remain on the system after the end of the attack while other may implement an auto-delete command and disappear soon after the attack is over. Where the ransomware is likely to store its malicious files is in some essential system folders like:

  • %Roaming%
  • %Windows%
  • %AppData%
  • %Local%
  • %Temp%

By being set to utilize sophisticated obfuscation techniques, this ransomware becomes able to evade detection and remain on the infected system even after the completion of its mission. In order to ensure its persistent presence on the system, GandCrab v5.1.4 could affect the Registry Editor. Among the affected keys could be the Run and RunoOnce as once affected by the ransomware it becomes able to manipulate their functionalities. By doing this its infection files are automatically executed on each system start.

Furthermore, the analyses of this GandCrab version reveal that the ransomware is able to access target browsers and steal all credentials saved there. So in case that you have saved the logins for your preferred websites you should immediately change all of the passwords.

Following all initial infection stages including the encryption that is explained in the next paragraph, GandCrab v5.1.4 drops a ransom note file in an attempt to blackmail you into paying a ransom fee. The content name of this file contains all random characters that are appended as an extension to all encrypted files followed by -DECRYPT.txt

So if for example you see the extension .FHNTRSDQDC after all your corrupted files you should also have a ransom note file called FHNTRSDQDC-DECRYPT.txt dropped on the system.

Beware that even a successful ransom payment does not guarantee the recovery of your files. So we recommend the use of alternative data recovery tools instead.

At the end of the process all of the following files of yours could appear corrupted and renamed with an extension of up to ten random alphanumeric characters:

  • Audio files
