Corrupted files can be recognized by the extension .BlackRuby appended to their names. In a file named how-to-decrypt-files.txt you can find a ransom message that primarily aims to urge you contact hackers at [email protected] and transfer a ransom of $650 to their Bitcoin address. In addition BlackRuby ransomware drops XMRig software to mine for Monero cryptocurrency.

BlackRuby Ransomware – Distribution

The analyzed BlackRuby ransomware samples point out that an executable file called WINDOWSUI.EXE triggers the infection. How this file could land on your system is via email spam messages, fake software update notifications, compromised third-party installers, malvertising and other shady techniques for ransomware distribution.

Ever since the ransomware went viral, email spam messages are the most preferred way of its distribution. Such emails are usually well crafted by hackers who hope that you will get tricked into installing the ransomware on your system. Common traits of emails carriers of malware are:

  • Spoofed email address and sender
  • Text messages that attempt to provoke sense of urgency
  • File attachment you need to download and see as soon as possible
  • In-text link you should follow in order to obtain important information

By opening the compromised file attachment, you automatically grant access to BlackRuby ransomware to your system. The same happens in case that you decide to click on the presented link and visit the web page.

Fake software update notifications may be designed to look exactly as the ones provided by the official product. As an example, you may check our article about a newly discovered pop-up that introduces a fake Java Update. Such notifications usually prompt you to download an executable file on your PC. Beware with any suspicious pop-ups that appear on your screen as they may serve as a gate for the malicious ransomware payload WINDOWSUI.EXE.

BlackRuby Ransomware – Infection Flow

Once BlackRuby ransomware is running on your system it initiates a sequence of malicious actions. In the beginning, it may establish connection with its command and control server in order to arm itself with all the needed files for the attack. There are several essential Windows system folders where the malicious files may be dropped:

  • %AppData%
  • %Temp%
  • %Roaming%
  • %Common%
  • %System32%

When BlackRuby got all malicious files on the compromised host, it may access the Registry Editor to add specific values under the Run and RunOnce sub-keys. The ransomware targets these two keys because they have the functionality to execute predefined files on each Windows system launch.

Furthermore, by contaminating these keys BlackRuby is able to display its ransom note on the screen at the end of the attack. The ransom note file is called how-to-decrypt-files.txt and could be found on the desktop. It primarily aims to urge you contact hackers at [email protected] and transfer a ransom of $650 to their Bitcoin address. However, if you don’t want to lose your money and get tricked again, it is better to try to overcome the problem with the help of reliable and secure solutions.

Below you can read the whole ransom message and see how it looks like:

That’s why you should utilize a quality anti-spyware solution to remove all files associated with the devastating BlackRuby infection.
