[SingCERT] Unsecured Virtual Network Computing (VNC) Configurations

Virtual Network Computing (VNC) is an open-source desktop sharing technology that enables users to access and control their home computers remotely over the Internet. Examples include enabling remote technical support to critical systems, allowing users to work from home, accessing home surveillance systems remotely from workplace, etc. An unsecured VNC configuration results when users use VNC without a password, thus causing them to be vulnerable to attackers who are constantly scanning the internet for loopholes.
