Smart Home Security Risks for High-Profile Households
A smart home is only as secure as its weakest device, and for an executive, athlete or family office principal, that weak point can reveal when the house is empty, who lives there and what the household’s routines are. The main risks are weak or default credentials, unpatched devices, shared networks and cloud accounts without multi-factor authentication. They are manageable when digital and physical protection are planned together. AMERINE is licensed in Texas and serves clients worldwide through vetted, licensed local providers. We treat the connected home as part of one security picture, not as a gadget problem.
TL;DR
-
Every added device can become an entry point. Research from the EU’s cybersecurity agency says a smart home is as vulnerable as its most vulnerable component.
-
For a public or high-net-worth household, the real danger is the information: presence, absence, routines and the Wi-Fi network behind them.
-
The fixes are mostly discipline: multi-factor authentication, unique passwords, automatic updates, a separate network for smart devices and retiring unsupported hardware.
-
Travel raises the stakes, because an empty house with connected systems is the moment an exposed account matters most.
-
A written assessment of the property, the accounts and the staff who touch them comes before any new technology.

Why a connected home is a different risk for a public household
Most consumer advice assumes an anonymous household and an opportunistic attacker. That is the right model for a typical family. It is the wrong model for someone whose name, employer, net worth or schedule is of interest to others.
For an executive, the home network often carries board materials, banking, personal email and the family’s devices on the same router as a smart speaker. For a celebrity or athlete, a camera feed or a door log is information that others would pay for. For a family office, the house is staffed by people who each hold a code, an app login or a Wi-Fi password.
The NIST guidance on smart homes states plainly that smart home devices pose security and privacy risks. A systematic review of 63 studies, published in 2023 in a peer-reviewed journal, found that smart homes may threaten confidentiality, authentication and control of the system, with privacy intrusion the most commonly studied harm. For a high-profile household, privacy intrusion is not an annoyance. It is the first step of a targeting effort.
How attackers get in
Smart home vulnerabilities cluster around a few repeatable weaknesses. None of them requires a sophisticated adversary.
Default and weak credentials
An academic survey of smart home vulnerabilities notes that default credentials are often published on the vendor’s own website and are frequently easy to guess. That makes unauthorized access to devices and home networks straightforward, and it opens the door to identity theft and social engineering. The UK government’s smart device guidance gives the simple rule: if a device ships with an obvious password, change it, and turn on two-factor authentication where it is offered.
One compromised device becomes a foothold
The ENISA Threat Landscape for Smart Homes report explains that every additional device may introduce a vulnerability, and that one compromised device can eavesdrop on network traffic and serve as a starting point for attacking others. The report is from 2014, but the principle has only become more relevant as homes have added devices.
Flaws in the app and the bulb
In August 2023, researchers disclosed four vulnerabilities in a popular smart bulb and its companion app. Security press reported that the most severe, scored 8.8 on the CVSS scale (a standard 0 to 10 severity rating), let a nearby attacker retrieve the user’s passwords and manipulate devices, and that the app could be used to extract the home Wi-Fi name and password. The lesson is not about one brand. A light bulb can hold the key to the network the rest of the house depends on.
Exposed cloud data
The vendor’s servers are also part of your home. In February 2025, a researcher reported that a database holding 2.7 billion records from a China-based maker of IoT devices was left without password protection, with Wi-Fi names, passwords, IP addresses and email addresses among the records. You can configure your own router perfectly and still be exposed by a supplier you have never heard of.
What a breach actually exposes
For most households the worst case is a privacy loss. For a principal, it is usable intelligence.
ENISA notes that the many sensors in a smart home log fine-grained behavior and produce significant information about inhabitants, including regular habits, presence or absence, health and preferences. Put plainly, thermostat patterns, lock logs and camera motion alerts tell an observer when you leave, when you return and which rooms are in use.
The UK guidance adds that devices have, rarely, been controlled by someone else, often to frighten the victim. For a family with a public profile, intimidation is a realistic aim, not a remote one.
This is why we connect smart home risk to the wider pattern of executive targeting: account takeover on a family member’s email, doxxing that publishes an address, phishing aimed at an assistant, and a connected house that confirms the occupants’ routines. Our guides on digital executive protection and cybersecurity for high-net-worth individuals cover those adjacent threats.
Where the exposure is greatest
Not every device carries equal risk. Rank them by what they control and what they record.
| Device or connection | Why it matters | What it can reveal or enable |
|---|---|---|
| Router and Wi-Fi | Every other device depends on it | Traffic, other devices, stored network passwords |
| Cameras and video doorbells | Record the household and its visitors | Occupants’ routines, images, live feeds |
| Smart locks and garage controls | Control physical entry | Entry logs, remote opening if the account is taken over |
| Alarm and automation hubs | Tie the system together | Rules, presence detection, ability to disarm |
| Voice assistants and speakers | Always listening for a wake word | Household conversation habits, linked accounts |
| Low-cost bulbs, plugs, sensors | Built for easy setup, not for strong security | A path into the network |
ENISA observes that small, low-cost, interconnected devices may lack mature security functions because they were designed mainly for easy setup and connection. It also notes that homes use several protocols at once, such as Wi-Fi, Bluetooth and ZigBee, each of which is a separate route in. Many devices cannot encrypt communications at all, because of limited power, added cost or the difficulty of getting it right.
CISA, the U.S. cybersecurity agency, makes a related point in its guidance on securing the Internet of Things: interconnection increases the consequences of known risks and creates new ones, and attackers can infect large numbers of devices at once, using them as part of a botnet (a network of hijacked devices) to attack other computers.
The house when you are not in it
Travel is when connected-home risk and physical risk meet. A principal on a long-haul flight, a family at a second residence or a team attending a multi-country event leaves behind a house that is empty, remotely controllable and, often, announced by social media.
Three things matter most while you are away:
-
Remote access. Anyone with your camera or lock login can see and act on the house from anywhere. A compromised account does not need to be near the property.
-
Presence data. Lighting schedules, thermostat setbacks and camera alerts show an empty house to anyone who can read them.
-
Your own devices. The phone and laptop you travel with hold the credentials for the home. Travel device hygiene protects the house as much as the trip. Our guide on cyber and digital hygiene for travelers covers the habits for large international events.
For a practical look at the physical side of leaving a home unattended, this article on protecting a home while away covers how connected systems fit into a vacation routine.
When a household moves between countries, the picture multiplies: different networks, different mobile carriers, different local support. AMERINE coordinates through vetted licensed local providers wherever a client travels, and plans the digital and physical arrangements together before departure.
A hardening routine that works
The NIST researcher behind the seven-tip guide published in April 2025 recommends multi-factor authentication, no password reuse, careful privacy settings, automatic updates, a separate network for smart devices and research before buying. Here is that advice turned into a routine for a household that has more to lose.
-
Inventory every connected device. List cameras, locks, hubs, speakers, televisions, appliances and the accounts tied to each. Most households find devices they forgot they had. Include the ones installed by contractors.
-
Change every default credential. Give each device and each account its own strong, unique password, stored in a password manager. The UK guidance flags guessable defaults such as “admin” as the first thing to change.
-
Turn on multi-factor authentication everywhere it exists. Start with the accounts that control cameras, locks and alarms, then the email account that can reset them all.
-
Separate the networks. NIST advises putting smart devices on a different Wi-Fi network from the computers that hold sensitive financial documents. For a principal, that means a dedicated network for the connected home, and another for work and family devices.
-
Set updates to automatic. NIST’s research found that many people did not know whether their devices were being updated. If a device can no longer receive updates, NIST recommends replacing or retiring it.
-
Reduce what is connected. CISA suggests asking whether a device needs constant internet connection at all before you connect it. A door that does not need remote opening should not have it.
-
Check what the device does with your data. Review privacy settings and turn off functions you do not use. Australia’s Personal Cyber Security Handbook also recommends researching a device before purchase, since manufacturers provide different levels of security.
-
Review access after any change. Staff changes, a new contractor or a guest stay should trigger a new look at who holds codes, app logins and the Wi-Fi password.
This routine reduces the common risks. The harder part is applying it across several properties, several family members and a rotating cast of people who have access. That is where a plan written for your household, not a generic checklist, earns its keep.
The people who touch the system
A smart home is also a human system. An executive assistant may manage the camera app. A house manager may hold the alarm code. A contractor may have set up the hub and kept the admin login.
The controls that matter are old-fashioned ones: who has access, how it is granted and how it is removed. Shared logins make it impossible to know who did what. A departed employee’s access that is never revoked is a standing exposure. Our article on household staff vetting explains why the quietest vulnerability in a large household is often a person, not a device.
For properties with serious technology, the estate security technology guide shows how cameras, access control and alarms are specified so that they work together without creating new weak points.
Where a security assessment fits
A household can follow every tip above and still miss the connections between them. A camera feed that is secure may still show a gate code. An alarm that is hardened may still be tied to an email account that is easy to phish. Risk lives in the seams.
An assessment looks at the property, the network, the accounts, the routines and the people around them as one system, then states the priorities in writing. Our security assessments and threat analysis work follows that order: assess first, recommend second, and confirm the scope in writing before anything is installed or staffed. The threat assessment process is described in more detail on our blog.
Our perspective
We start from a simple view: a house is not secure because it has good technology. It is secure because someone has thought through who might target the people inside, how they would learn about them and what they would try first.
Smart home risk is a good example. The devices are not the threat. The information they generate is. When a camera app, a lock log and a family member’s email account can each tell a stranger when the house is empty, the physical plan and the digital plan are the same plan.
That is why our founder’s Secret Service background shapes a planning-first method. We assess before we recommend, we confirm scope and responsibilities in writing and we use low-visibility operators so protection does not advertise the principal. We coordinate with executive assistants, household staff, corporate security teams and legal counsel, because the people around a principal are part of the system.
The same logic applies when you travel. Our subscription memberships give members priority access to our team, so a plan, a contact and a way of working already exist when something changes in a hurry. We cannot promise deployment anywhere, and we do not claim local offices. We are licensed in Texas and coordinate through vetted licensed local providers in the rest of the world, with the arrangements confirmed in writing beforehand.
If your household has grown more connected than anyone has reviewed, that review is the best first step.

FAQ
Are smart home attacks usually targeted at specific people?
Most are opportunistic, aimed at weak passwords, old firmware and exposed networks. For a public figure or executive, targeting is more plausible, because the information in a connected home has direct value to someone watching that person. Plan for both.
Is a separate Wi-Fi network really necessary?
It is one of the most practical steps. NIST advises placing smart devices on a different network from computers that hold sensitive financial documents, so a compromised bulb or camera cannot easily reach the machines that matter. Most modern routers support a guest or secondary network for this purpose.
What should I do with a device that no longer gets updates?
Replace or retire it. NIST’s guidance says that an older device that can no longer receive updates should be considered for replacement, because known flaws stay open indefinitely. If it must stay for a while, keep it on its own network with as few functions enabled as possible.
Does travel change smart home risk?
Yes. While you are away, remote access, presence data and the devices you carry are the main exposures. Review who holds logins before you leave, use multi-factor authentication on every home account and keep your travel devices updated. For multi-country movement, we plan this alongside the physical arrangements.
Can AMERINE support clients outside Texas?
Yes. AMERINE is licensed in Texas and works anywhere in the world through vetted licensed local partners, for domestic and international travel, inbound and outbound movement and large events. We do not claim local offices or in-country staff.
