Remove Leitkcad Ransomware Virus

A ransomware infection dubbed Leitkcad has been detected in active attack campaigns. This threat is developed to infect computer operating systems by installing malicious files without generating any notifications. Its presence on an infected PC can be noticed at the end of its attack – when it is too late for taking some prevention steps. The moment its ransom message (help-leitkcad.txt) appears somewhere on the system, it means that the ransomware has successfully encrypted your personal files and renamed their names with the .leitkcad extension. Since ransomware infections like Leitkcad tend to use complex cipher algorithms for data encryption, these programs leave files completely inaccessible.

Even though hackers insist on paying them a hefty ransom fee, we advise you to avoid following their instructions and try to remove malicious files from the infected PC with the guide that follows.

Leitkcad Ransomware – How Did I Get It and What Does It Do?

The Leitkcad ransomware is a malicious piece of code that has recently been released in the wild. It may land on computer operating systems via freeware installers, fake software updates, email attachments, advertisements, etc.

The moment the payload file of Leitkcad ransomware runs on a target operating system, it triggers a long sequence of malicious operations that enable it to evade detection, misuse system functionalities, and eventually encode valuable personal files.

Due to the complexity of the changes applied to your files, they 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 a file that is encrypted by this nasty ransomware is its changed name. This ransomware is set to append the malicious extension .leitkcad to corrupted files’ names.

After Leitkcad ransomware encrypts files, it drops a ransom note on the system. This note is a text file named help-leitkcad.txt. You can see what the note reads right below:

Caution!!!
Your files on this computer have been encrypted due to security issues.
To restore it you should write to the online chat.

To decrypt files follow the instructions below:

1. Open in any browser the link: {URL}.
2. Or download and install TOR browser (if TOR blocked in your country you need to install VPN and download it) and follow the link: {.onion_URL}
3. To chat with operator you need to fill the next information on chat page:
– your ID:
– personal key:
– your E-Mail

Attention!
Do not try to reload your PC.
Do not try to recover information using third party software.
Do not attempt to use antivirus.
Do not try to uninstall programs.
All these actions will lead to data loss and unrecoverable.!

We know that you need to restore .leitkcad files but we advise against transferring money to cybercriminals. 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 new ransomware viruses or commit different criminal activities.

For the sake of your security, we recommend you to clean your computer from present malicious files and wait for an eventual release of a free decryption tool. Meanwhile, you may want to consider the help of alternative data recovery methods.
