FDFK Virus (Matrix Ransomware) – Spread and Imact

Hackers utilize various shady methods for the spread of FDFK virus’ payloads. All methods aim to trick you into starting the payload on your PC without considering the risk that it will trigger a ransomware infection process.

The main spread technique is believed to be malwspam. It enables bad actors to send spam email messages to large number of people around the globe. These messages usually pretend to be sent by legitimate companies/businesses like internet providers, banking institutions, popular websites, delivery companies and sometimes governmental institutions.

The senders of these emails may pose as representatives of the above-mentioned services in an attempt to make you more prone to follow the instructions provided by the text messages. The text messages usually contain strong call-to-action that urges you to review the content of an attached file or a presented link as soon as possible. In case that you fall victim to their scam, you unnoticeably grant the ransomware access to your system.

The so-called FDFK files virus known to be a Matrix ransomware strain, creates lots of additional malicious files soon after its executio on the system. Тhere are several folders that are likely to store these files:

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

Afterward the code of the initial payload could trigger predefined commands that execute malicious files in an exact order. The sequence of malicious actions enables the ransomware to plague essential system components and complete its attack.

The FDFK virus was identified to belong to the Matric ransomware family. Being a strain of this family it is likely to apply a combination of two sophisticated cipher algorithms (AES-128 + RSA-2048) to encrypt target types of files.

During this process the ransomware transforms parts of the original code of target files in order to restrict the access to the data they store. Unfortunately, an infection with this crypto virus could lead to the corruption of valuable files including but not limiting to your:

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

Upon encryption, all corrupted files appear with three extensions the last of which is the extension .FDFK. The encryption process is associated with the generation of the unique decryption key that is supposedly able to recover encrypted files. However, you should not believe hackers as they could trick you again by sending you a broken decryption key that won’t decrypt your .FDFK files.

Soon after the ransomware completes system and data modifications it drops a ransom note file called !FDFK_INFO!.rtf in one or several folders. The text presented by this message reveals you the presence of the ransomware and blackmails you into paying hackers certain ransom for a decryption solution.

Below you could find how a step-by-step FDFK ransomware removal guide that could be helpful in attempting to remove FDFK virus.
