JeFf thE rAnSOmwArE v1.0 – In-Depth Description

JeFf thE rAnSOmwArE v1.0 is a virus that supposedly encrypts your files and shows a window with instructions on the screen of your computer system. The extortionists want you to pay a ransom for the alleged restoration of your files and restoration of your computer system back to normal.

JeFf thE rAnSOmwArE v1.0 cryptovirus makes entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows environment (such as locking your computer screen). Such entries are typically designed in a way to launch the virus automatically with each start of the Windows operating system.

After the “encryption” process of the JeFf virus is complete, a ransom message will be displayed on your computer screen. You can see its contents from the following screenshot given right down here:

The ransom note states the following:

JeFf thE rAnSOmwArE v1.0
WHAT YOU DO TO MY COMPUTER??!??!!!
eng

RECOVER MY FILES | EXIT

There is also a second image that will appear inside the custom-made GUI interface, which is the following:

The message in it states:

PRESS HERE TO STOP THIS
CREEPY SOUND AND VIEW WHAT
HAPPENED TO YOUR COMPUTER

The note of the JeFf thE rAnSOmwArE v1.0 ransomware is still unfinished, but claims that you have to recover your files and computer. When the ransom note is finished you will probably be demanded to pay money for the supposed restoration. However, you should NOT under any circumstances pay any ransom sum, even if your files are truly locked. Your files may not get recovered, and nobody could give you a guarantee for that. Moreover, giving money to cybercriminals will most likely motivate them to create more ransomware viruses or commit different criminal acts.

JeFf thE rAnSOmwArE v1.0 – Encryption Process

The encryption process of the JeFf thE rAnSOmwArE v1.0 ransomware is not known to work at the time of writing of this article. That might change in the future, as the ransomware might be in a developmental phase and implement the encryption feature at a later point in time.

It is currently unknown if any version of this ransomware actually encrypts files. The encryption feature might be implemented in the future, especially if the malware is still under development. Currently there is no information regarding which types of files might get encrypted if such a feature was present in the malicious application. If information about the file extensions which might get encrypted in the future is found, this article will get duly updated.

The files which are used the most by users that would probably get encrypted will probably be from the following categories:

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

The JeFf virus threat can still lock your screen and demand a ransom as payment.

The JeFf 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

If the above-stated command is executed that will make it harder to restore your computer back to its state before becoming infected with the threat. In the future that would also help make the encryption process more viable. That is due to the fact that the command eliminates one of the prominent ways to restore your data as well. If your computer system was infected with this ransomware and you wish to find out how you could potentially restore your system back to normal, continue reading below.
