Tunnelblick, the go-to graphical interface for OpenVPN on macOS, just got safer thanks to a major security fix. The security issue, discovered by PT SWARM's Egor Filatov, put Apple users at risk—even those who thought they were safe after deleting the app. If exploited, the vulnerability allowed attackers to elevate their system privileges and steal data. Companies whose employees use Tunnelblick on their work devices could face the risk of a cyberattack spreading to the corporate IT infrastructure.
