Sometimes devices on our network have more than one way of communicating, be it wired or wireless. Both of these modes of communication lead back to the same device, so if an attacker can take control of it they can use the device to make a bridge outside of a VLAN or similar isolation.
BridgeBlock is a security tool designed to prevent wireless bridging attacks by monitoring active network interfaces on macOS devices. It ensures that if both wired and wireless interfaces can access the same URL, the WiFi is automatically turned off, preventing unauthorized network bridging and closing the attack vector.
Open Source Commitment
As a strong proponent of open-source software, BridgeBlock is released under the GPLv2 license. I encourage community contributions and warmly welcome patches and feature enhancements through pull requests.
