Summary: As the “Matter” smart home standard becomes mandatory for new devices in 2026, a vulnerability in the “Matter Bridge” function has been disclosed. It allows an attacker who compromises a low-security device (like a smart bulb) to pivot through the bridge and access other devices on the same Thread network, including work-from-home laptops.
Business Impact: “Home Office” Lateral Movement. With hybrid work being the norm, corporate devices often share networks with consumer IoT. This flaw breaches the logical segmentation that employees rely on for security at home.
Why It Happened: The complexity of bridging legacy protocols (Zigbee/Z-Wave) to Matter created an authentication gap. Attackers leverage this to bypass the stricter security controls of the Matter standard itself.
Recommended Executive Action: Update your “Remote Work Policy.” Mandate that all corporate devices must connect to a dedicated “Guest Wi-Fi” or use a corporate VPN that enforces strict split-tunneling to isolate the device from local IoT traffic.
