A recently discovered vulnerability in both the Chrome and Firefox browsers could cause some security headaches for frequent VPN users. Recent updates to both browsers have enabled WebRTC by default, an API that allows for browser-to-browser communication and is generally used in VoIP calling, video chat, and other online applications, without the need for installing any extensions or plug-ins. The vulnerability effects any VPN user with the latest versions of Firefox or Chrome, using either Windows or Mac OS X. As most know, VPN services are generally utilized to mask a persons public IP address when communicating over the Internet, effectively providing a level of anonymity when browsing websites and using other Internet based services. All outbound Internet traffic is sent over an encrypted tunnel to the VPN providers’ servers, and then routed to the Internet from there.
