Though using a VPN makes you secure, like all online things it can also be hacked, although the likelihood is highly reduced.
A VPN provides you security by encrypting your online browsing. Through the use of military-grade encryption and protocols, the software makes sure that hackers can’t access your information. Additionally, most VPN services have extra security features allowing them to prevent users from entering harmful websites. While this allows you to surf the internet with no worries 99.99% of the time, it was discovered last year that VPNs using an OpenVPN protocol can be the subject of a security breach.
This fragility, known as VORACLE attack, takes advantage of VPNs that use compression with the aforementioned protocol. Users are particularly vulnerable if they’re visiting a website with HTTP connection. Any web browser, with the exception of Google Chrome, is susceptible to a VORACLE attack. Despite this, it isn’t that simple to perform an invasion. Attackers have to be in the same network as the targeted user and they have to either control the visited website or have previously inserted a malicious code to a legitimate site.
By disabling compression in the OpenVPN protocol, the possibility of a VORACLE attack is reduced to none. While discussions are still ongoing on whether compression should be definitively disabled in the open source OpenVPN project, as of now, the tool is disabled by default, thus protecting those who are using VPNs with this protocol.
