What is Leitkcad Ransomware

Leitkcad is a pure example of crypto-malware that runs encryption over personal data to garner a so-called ransom. The most vivid symptoms hinting at the Leitkcad’s presence is the assignment of .leitkcad extension. In other words, it will be seen at the end of each file affected by malware. For example, a file like 1.mp4 will be changed to 1.mp4.leitkcad and reset its original icon. Then, once all of the files are changed, the virus moves to the next phase creating a note called help-leitkcad.txt. It contains information on the encryption as well as instructions to restore your data.

Attention!
Do not try to reload your PC.

Do not attempt to use antivirus.
Do not try to uninstall programs.
All these actions will lead to data loss and unrecoverable.

Cybercriminals say that you should contact an operator and fill in your ID, personal key, and e-mail via the chat page. The link to it can be opened only by using the Tor browser, which has to be downloaded by victims. Then, after establishing contact with cybercriminals, you will receive further instructions on how to purchase the decryption software. Also, it is worth-noting that rebooting and altering encrypted files can lead to permanent loss. Extortionists set certain algorithms that help them detect your activity. This means that if you refuse to comply with any of the above warnings, your files will be deleted momentarily. Unfortunately, there are no third-party instruments that could decrypt data affected by Leitkcad Ransomware at this moment. Although the only option seems to be paying the ransom, we recommend you against it because there is a risk of getting financially fooled. The best decision, in this case, would be deleting Leitkcad Ransomware and recovering your data from a backup copy. If you do not have one created prior to the infection, you can still try to decrypt your data using some third-party utilities. All of the steps to run both uninstallation and decryption of data can be found in the article below.
