Tunca Ransomware Virus – Encryption Process

What is known for the encryption process of the Tunca ransomware is that every file that gets encrypted will receive the .tunca extension. The encryption algorithm used to lock the files is the AES algorithm.

The targeted extensions of files which are sought to get encrypted are currently unknown and if a list is discovered, it will be posted here as the article gets updated. 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

The Tunca cryptovirus could be set to erase all the Tunca 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 encryption process more efficient. That is due to the fact that the command eliminates one of the prominent ways to restore your data.
