Currently, samples of this threat are lurking around the web. Guesses are that the spread is realized mainly via malspam campaigns. Malspam enables hackers to deliver malicious code on users’ devices with the help of massive email campaigns. Spam emails which are part of attack campaigns usually contain one or more of the following components:

  • A link to compromised web page that is set to download and execute infection files directly on the PC. The URL address to this page may be presented in the form of an in-text link, banner, image, button or full URL address.
  • A malicious file attachment that is presented as legitimate document by the text message. It could be uploaded in a .rar or .zip archive. Such a file could be set to evade active security measures and trick you into running the ransomware on your PC.

Once started on a computer system .dqb ransomware attempts to evade detection by running specific checks for active security measures. When ready, it initiates a long sequence of malicious operations that affect the settings of some essential system components and enable it to encrypt target files.

As a part of Dharma ransomware family, .dqb virus encrypts target files by utilizing the strong cipher algorithm AES. The encryption process is realized after the activation of a built-in cipher module. That module is designed to scan all drives for certain types of files so it can apply changes to their code.

Due to the complexity of applied changes, encrypted files remain inaccessible until their code is reverted back to its original state. Unfortunately, you may not be able to view the information stored by the following files of yours:

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

One way to recognize an encrypted file is by the appearance of the extension .dqb in its name. Additionally, you could see the email address [email protected] as an extension. This email address is associated with cyber criminals who stand behind .dqb ransomware attacks. It could be also noticed in the ransom message (RETURN FILES.txt) that appears at the end of the infection process.

We know that you need to restore .dqb files but what we should recommend you is to refrain from transferring your money to cybercriminals. Otherwise, you risk losing both your valuable files and money.

For the sake of your security, it is advisable to clean your computer from present malicious files and consider the help of alternative data recovery methods.
