TunnelVision: a threat to VPN security
The vulnerability know as "TunelVision" refers to a flaw that affects all VPNs (Virtual Private Networks) when they connect to a hostile metwork and fail to fulfill their intended purpose. This occurs through the combination of two vulnerabilities present in most VPNs.
The first vunlnerability reates to inadequate authentication of VPN servers, allowing attackers to access the network and intercept trafic outside the encrypted tunel.The seconf vulnerability pertains to insufficient data encryption, enabling attackers to access user's sensitive information.
TunelVision was recently presented at USENIX Security 2023 by researches from various American universities. It's essential to note that attackers can exploit this vulnerability to intercept traffic outside the tunnel and access confidential use data.
VPN users should take precautions to protect against TunnelVision, such as using secure VPN servers and ensuring proper data encryption.
