Smart home hacks are rare. Most problems come from weak passwords or devices that never got updates, not from attacks on one home. Strong, different passwords and regular updates block most of it.
News of a recent hacking incident involving over 120,000 home cameras in Korea has once again raised alarms about the vulnerabilities of smart home devices. While such reports often evoke fears of cybercriminals spying on families or breaching homes, experts emphasize that context is important to properly understand these risks.
Contrary to popular belief, smart home hacking incidents are relatively rare. "Smart home hacking headlines can look scary, but most threats come from weak passwords rather than targeted attacks", said Kurt "CyberGuy" Knutsson. Many vulnerabilities stem from poor user habits, such as weak passwords or unpatched devices, rather than sophisticated attacks by strangers. Additionally, modern smart home brands frequently issue updates to secure devices against emerging threats, including those related to artificial intelligence.
Demystifying smart home security risks
Despite fears of hackers circling neighborhoods with advanced tools, the reality of smart home hacking looks quite different. Real-world data suggests that most criminals still rely on traditional, low-tech methods, such as targeting unlocked doors or windows. "Burglars still choose low-tech methods. They look for unlocked doors or easy entry points", Knutsson explained. The technical and logistical challenges of hacking individual smart homes make such efforts uncommon.
The majority of smart home breaches occur through a handful of common attack methods:
1. Automated online attacks
Bots programmed for brute force attacks scan the internet for weak passwords and outdated accounts. These automated attempts focus on exploiting vulnerabilities wherever they are found, not necessarily targeting specific homes. Strong passwords can effectively block these attacks.
2. Phishing scams
Phishing emails masquerading as smart home brands can trick users into providing login credentials or clicking malicious links. Even non-targeted phishing attempts can expose Wi-Fi information, leading to broader breaches.
3. Data breaches from manufacturers
Hackers often target the servers of Internet of Things (IoT) companies, stealing account credentials or stored footage. While these incidents rarely result in direct attacks on individual homes, they can place users’ data at risk.
4. Device communication vulnerabilities
Although older IoT devices were vulnerable to intercepted communications, most modern devices utilize strong encryption to block these attacks. Such methods are now rare in practice.
5. Bluetooth exploits
Bluetooth flaws occasionally allow hackers to breach devices, but manufacturers generally respond quickly with updates. These risks are minimal for newer devices that receive regular patches.

Who is actually hacking smart homes?
When breaches do occur, they are often carried out by individuals with some level of access to the home or its accounts. For instance, former acquaintances, such as ex-partners or roommates, may exploit known passwords to gain access. In other cases, employees of security companies have been reported misusing internal access to spy on customers.
Other threats include data thieves who steal and sell account details, as well as scammers who send fake ransom demands claiming to have hacked devices – though these claims are often baseless. Some potential risks are also associated with foreign manufacturers banned by the FCC for security reasons.
Vulnerable devices and how to protect them
Certain smart home gadgets carry higher risks due to overlooked security settings or outdated protocols. For example, smart fridges and Wi-Fi baby monitors may include default passwords that users forget to change or rely on older, less secure technologies. Smart bulbs with temporary open networks during setup and smart speakers that allow voice ordering by anyone present also pose potential risks.
To safeguard smart home setups, experts recommend the following steps:
- Use strong, unique passwords: Ensure your router and smart home accounts have complex passwords to prevent brute force attacks.
- Enable two-factor authentication (2FA): This extra step adds another layer of security to accounts.
- Keep devices updated: Install firmware updates promptly to close security vulnerabilities.
- Secure your Wi-Fi network: Use WPA3 encryption, update router firmware, and rename default network names.
- Choose reputable brands: Look for manufacturers that prioritize user privacy and offer regular updates.
- Store footage locally: Opt for devices with local storage options, such as SD cards, to minimize risks associated with cloud breaches.
A balanced perspective on smart home security
While incidents like the Korean camera breach make headlines, the actual risks to smart home devices are often overstated. Knutsson pointed out, "Smart homes feel intimidating when scary headlines surface. But when you look at real-world data, you see far fewer risks than the stories suggest." Most vulnerabilities can be mitigated with good practices, such as securing passwords, enabling two-factor authentication, and keeping devices updated.
By adopting these measures, individuals can enjoy the convenience of smart home technology without compromising security. However, users should remain vigilant about evolving threats and prioritize privacy in their connected home ecosystems.
What does this mean for your home?
You do not need to fear your smart devices. Use a strong, different password for each account and turn on updates. When someone moves out, change the passwords. Watch out for emails that ask for your login, even if they look real.

What One Sound Choice clients say
We one a vacation home and were concerned with security when we are not there. 1 Sound Choice provided camera that allowed us to record all activity for a month and we could dial into the system from the internet. The system also will automatically flash lights inside the home to discourage intruders from entering.

Smart home safety questions
Are smart home hacks common?
No. They are rare. Most trouble comes from weak passwords or devices that were never updated.
What is the easiest way to protect my devices?
Use a strong, different password for each account. Turn on updates so your devices get fixes.
Are new devices safer than old ones?
Usually. Most new devices use strong encryption and get regular updates from the maker.
What should I do when a roommate or ex moves out?
Change the passwords on your smart home accounts and Wi-Fi. Remove their access from the apps.
