The discovery of a backdoor in an Internet-connected bed highlights security concerns in smart home devices, writes Zachary Amos, Features Editor of ReHack Magazine
Smart home devices are rapidly becoming a staple in UK households, offering convenience, automation and energy efficiency. From speakers that control lights and music to security cameras that provide remote monitoring, these products promise to simplify daily life. However, while they enhance comfort and connectivity, many IoT items have weak privacy measures, which makes them prime targets for cybercriminals.
Default passwords, outdated firmware and unencrypted data create easy entry points for hackers, putting personal information and entire home networks at risk. As the demand for smart technology grows, so does the need for stronger security protocols to keep connected houses safe from cyberthreats.
Why smart home devices are vulnerable
Many IoT manufacturers focus on convenience and affordability, often at the expense of security. This leaves millions of smart devices vulnerable to cyberattacks.
In 2022, cyber criminals launched over 112 million attacks on IoT devices worldwide. After one is compromised, attackers can gain access to the entire home network, putting personal data, surveillance feeds and financial accounts at risk. As smart home technology improves, security must become a priority to prevent homes from becoming an open door for cyberthreats.
The smart device security flaw
A shocking vulnerability was discovered in an Internet-connected smart bed designed to regulate sleep temperature. Someone who purchased the device found that it contained a backdoor that cyber criminals could exploit to gain unauthorised access. They realised that aquarium chillers could provide similar temperature control without the risks of potential hacking and data privacy issues.
While a bed might seem like a harmless household gadget, its security flaw highlights a much bigger issue. Many IoT devices — even the most unexpected ones — can serve as weak points in a home network. This case underscores how smart devices often prioritise functionality over security, which creates hidden risks for consumers who assume their devices are safe.
How cyber attackers can exploit these weaknesses
Hackers can exploit weak IoT security to gain unauthorised access to smart home devices, turning them into tools for surveillance, data theft and large-scale cyber attacks. Malicious actors can compromise cameras and microphones to spy on homeowners, invading their privacy without their knowledge. They can also hijack smart lock systems — which allow users to control entry points via an app — giving attackers remote access to a home.
Once inside a vulnerable network, hackers can steal sensitive data and put entire households at risk. On a large scale, cyber criminals can hijack thousands of unprotected IoT devices to create powerful botnets, which can disrupt websites and online services worldwide. Without strong protections, smart homes can quickly become a criminal’s playground.
Protecting your smart home from cyber threats
As smart home technology expands, so do the risks associated with poorly secured IoT devices. Following best practices can significantly reduce the chances of cybercriminals exploiting their devices.
- Change default passwords immediately: many devices come with weak, factory-set passwords that hackers can easily guess. Always set a strong, unique password for each device
- Enable two-factor authentication: if available, activate 2FA to add extra security, making it harder for attackers to gain access
- Regularly update firmware and software: manufacturers release updates to fix vulnerabilities. Ensure automatic updates are enabled or manually check for them regularly
- Disable unnecessary features: many devices come with default settings that enable remote access or other features that may not be needed. Turning these off can reduce security risks
- Use a separate Wi-Fi network for smart devices: creating a dedicated IoT network prevents hackers from easily accessing personal data on computers and smartphones if a smart device is compromised
What manufacturers should do
IoT manufacturers must make privacy a priority from the start to protect consumers from cyberthreats and prevent vulnerabilities that hackers can easily exploit. Despite growing concerns, only 52% of IoT manufacturers in the UK comply with password security provisions. To close these gaps, manufacturers must implement robust coding practices, ensure encrypted data transmission and provide regular firmware updates to patch vulnerabilities.
Regulations like the UK’s Product Security and Telecommunications Infrastructure (PSTI) Act and the EU Cyber Resilience Act (CRA) push companies to improve privacy standards. However, security must be built into the design of every device, not treated as an afterthought. As smart homes become more connected, stronger protocols protect consumers and maintain trust in IoT technology.
Protecting smart homes Without Sacrificing Security
Taking IoT security seriously protects personal data, privacy and home networks from cyberthreats. While smart devices offer unmatched convenience, balancing ease of use with robust measures is crucial to enjoying connected technology without compromising safety.
