FLKR Ransomware – Distribution Techniques

FLKR ransomware might spread its infection via various techniques. A payload dropper which initiates the malicious script for this ransomware is being spread around the World Wide Web, and researchers have gotten their hands on a malware sample. If that file lands on your computer system and you somehow execute it – your computer device will become infected.

In the screenshot given below, you can see the payload of the ransomware being detected by multiple security engines on the VirusTotal service:

Freeware which is found on the Web can be presented as helpful also be hiding the malicious script for the cryptovirus. Refrain from opening files right after you have downloaded them. You should first scan them with a security tool, while also checking their size and signatures for anything that seems out of the ordinary. You should read the tips for preventing ransomware located at the corresponding forum thread.

FLKR Ransomware – Detailed Analysis

FLKR is a virus that encrypts your files and places a .txt file, with instructions inside it, about the compromised computer system. The extortionists want you to pay a ransom fee for the alleged restoration of your files. Currently, lots of the victims are from Belarus.

The FLKR cryptovirus creates these files on a compromised computer system:

  • flkr.exe
  • delmeflk.bat
  • delmelaun.bat
  • launcher.exe

FLKR ransomware could make entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows environment. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows operating system.

After encryption the FLKR virus shows a ransom message located inside the following file:


You can see the contents of the INSTRUCTIONX.txt file, from the following screenshot provided down here:

The ransom message states the following:

To decrypt files – Jabber (xmpp) address: (if we are offline – you can write offline, its ok) PIN: 24

As seen above, the following jabber address is being used:


The previous version of FLKR ransomware used the same tactic for communicating through Jabber as described in the Files Virus article.

The note of the FLKR ransomware virus states that your files are encrypted. You are demanded to pay a ransom sum to allegedly restore your files. However, you should NOT under any circumstances pay any ransom sum. Your files may not get recovered, and nobody could give you a guarantee for that. Adding to that, giving money to cybercriminals will most likely motivate them to create more ransomware viruses or commit different criminal activities. That may even result to you getting your files encrypted all over again after payment.

FLKR Ransomware – Encryption Process

What is known for the encryption process of the FLKR ransomware is that every file that gets encrypted will become simply unusable. All encrypted files will receive the “” extension appended to them. Some malware researchers believe that this variant of the ransomware still uses the Blowfish encryption method by locking files by 512 bytes blocks.

Files for backups such as .bak and .tib are erased instead of being locked.

The cryptovirus skips any .txt, .mp3, and .avi files and does not encrypt them, nor any other files found in the following directories:

  • Windows
  • Program Files
  • Program Files (x86)
  • System Volume Information
  • Documents and Settings
  • Users
  • Install
  • Music
  • Intel
  • adfs
  • cpqsystem

An unfinished list with the targeted extensions of files which are sought to get encrypted is currently known to be the following:

→.dat, .dll, .doc, .docx, .exe, .pdf, .xls, .xlsx

However, if the list becomes more complete, the article will get duly updated with the new additions.

The files used most by users and which are probably encrypted are from the following categories:

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

Some researchers believe that the virus will encrypt any other extension which is not specifically mentioned above.

The FLKR cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

In case the above-stated command is executed that will make the effects of the encryption process more efficient. That is due to the fact that the command eliminates one of the prominent ways to restore your data. If a computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially restore some files back to their normal state.
