9,000 VNC servers are at risk of being exposed online

Security Researchers have discovered at least 9,000 exposed VNC (virtual network computing) servers that can be exposed online due to not using any authentication. It will allow threat actors to easily access their internal networks.

Virtual Network Computing is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol to remotely control another computer. It transmits the keyboard and mouse input from one computer to another, relaying the graphical-screen updates, over a network.

These servers are not properly secured, which will be due to negligence, error, or due to convenience of access But they can serve as entry points for unauthorized users, including threat actors with bad intentions.

This security issue is discovered by Cyble security researchers and found over 9,000 accessible servers without any authentication.

Exposed servers are located in China and Sweden, while the United States, Spain, and Brazil are in the top 5 unprotected VNCs servers.
