The attacks exploit weaknesses in protocol-infrastructure interactions across encryption, switching, and routing layers. Key primitives include Gateway Bouncing (exploiting IP-layer isolation gaps), Port Stealing (hijacking MAC-to-port mappings below the ARP layer), and Broadcast Reflection (injecting unicast payloads via broadcast frames without knowing the GTK). These techniques can be chained to achieve full man-in-the-middle positions, enable RADIUS secret brute-forcing, DNS/DHCP poisoning, and traffic decryption. The attacks affect all major operating systems and Wi-Fi vendors. Mitigations include VLAN segmentation, MAC/IP spoofing prevention, per-client randomized GTKs, and MACsec (IEEE 802.1AE) link-layer encryption. ## Full article daily.dev links to this article rather than hosting it.
