Pumas is a virus that encrypts your files and shows a window with instructions on your computer screen. The extortionists want you to pay a ransom for the alleged restoration of your files.

Pumas 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 Pumas virus will place a ransom note message inside a file called “!readme.txt”. You can see its contents from the following screenshot given down here:

However, you should NOT under any circumstances pay any ransom. 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.

Pumas Ransomware Virus – Encryption Process

What is known for the encryption process of the Pumas ransomware is that every file that gets encrypted will receive the .pumas extension. The encryption algorithms used to lock the files are AES and RSA 1024-bit.

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 Pumas 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 encryption process more efficient. That is due to the fact that the command eliminates one of the prominent ways to restore your data.
