Smart Homes, Dumb Security:
The Hidden Risks of Connected Living
The modern luxury home is filled with connected devices — from security cameras to smart locks to home automation systems. Each one represents a potential vulnerability.
The Paradox of the Connected Home
The luxury home has always been a statement of security and privacy. High walls, monitored access, discreet staff. But the same technology that makes modern homes more comfortable and convenient has introduced a new category of vulnerability that physical security cannot address.
The average affluent Australian home now contains between 20 and 50 connected devices. Each one has an IP address, a software stack, and a connection to the internet. Each one is a potential entry point for an adversary who knows where to look — and increasingly, they do.
The Six Highest-Risk Device Categories
Not all connected devices carry equal risk. The following categories represent the most common and consequential vulnerabilities we encounter in client homes.
Smart Security Cameras & Doorbells
The Risk
Many consumer-grade cameras use weak default credentials and transmit footage over unencrypted connections. Compromised cameras provide adversaries with real-time visibility into your home, your routines, and your family.
What To Do
Replace default credentials immediately. Ensure cameras use end-to-end encryption and are on a segregated network segment. Audit firmware update schedules.
Smart Locks & Access Control
The Risk
Bluetooth and Wi-Fi enabled locks can be vulnerable to relay attacks, firmware exploits, and credential theft. A compromised smart lock is a literal open door.
What To Do
Use locks from manufacturers with strong security track records and regular firmware updates. Maintain a physical key backup. Audit who has digital access credentials.
Voice Assistants
The Risk
Devices like Amazon Echo and Google Home are always listening for wake words — and their microphones can be triggered by ultrasonic signals inaudible to humans. Recorded conversations are stored on manufacturer servers.
What To Do
Disable voice assistants in sensitive rooms. Review and delete voice history regularly. Consider physical microphone mute switches for high-sensitivity areas.
Home Automation Hubs
The Risk
Centralised home automation systems (Control4, Crestron, Savant) offer significant attack surface if not properly secured. A compromised hub can provide access to every connected system in the home.
What To Do
Ensure automation systems are on isolated network segments. Require VPN for remote access. Audit third-party integrations and remove unused connections.
Smart TVs & Entertainment Systems
The Risk
Smart TVs contain microphones, cameras, and persistent internet connections. Many collect viewing data and have limited security update lifecycles. Compromised TVs can be used for surveillance or as network entry points.
What To Do
Disable built-in microphones and cameras where possible. Keep firmware updated. Place entertainment devices on a guest network segment isolated from primary systems.
Home Network Routers
The Risk
The router is the gateway to every device in your home. Default credentials, outdated firmware, and poor configuration are the most common vulnerabilities — and the most consequential.
What To Do
Use enterprise-grade routers with active security support. Change all default credentials. Enable automatic firmware updates. Conduct regular attack surface assessments.
The Network Is the Foundation
Individual device security matters, but the home network is the foundation on which everything else rests. A well-configured network limits the damage any single compromised device can cause through segmentation — keeping IoT devices, guest access, and primary computing on separate network segments that cannot communicate with each other.
We conduct weekly attack surface assessments of client home networks, testing the public-facing exposure of every connected system. In our experience, the majority of homes we engage with have significant, addressable vulnerabilities that have been present for months or years without detection.
A Note on Consumer vs. Enterprise Security
Consumer smart home products are designed for ease of use, not security. They are built to a price point, supported for limited periods, and often shipped with security as an afterthought. Enterprise-grade alternatives exist for most device categories — and for clients whose privacy and security warrant it, the investment is straightforward to justify.
The right answer is not to avoid connected technology. It is to deploy it thoughtfully, configure it correctly, and monitor it continuously.
