When you think of malware, your mind probably jumps to malicious downloads or email attachments. But it turns out, some pretty innocent-looking devices can also be used as sneaky vectors for malicious software. Here are five surprising gadgets that could become malware delivery systems, and how to protect yourself.
1. Headphones and Speakers
Yes, you read that right! Your trusty headphones or speakers could spread malware. This isn’t about plugging them into an infected device but rather using them to transmit data through sound waves. Researchers have demonstrated how malware can convert audio output devices into ultrasonic transmitters.
In one proof-of-concept attack called “AirHopper,” headphones were used to leak data from air-gapped computers by sending high-frequency audio signals that could be picked up by a nearby compromised device with a microphone.
While this kind of attack is rare and highly sophisticated, it shows that even your headphones can be weaponized. To minimize risk, always update your audio drivers and keep your system security tight.
2. Smart Light Bulbs
Your fancy smart lighting system could be more than just mood lighting — it could also be a way for hackers to infiltrate your network. Researchers have shown that some smart bulbs can be infected with malware, which then spreads to other connected devices.
A notable example is the “Philips Hue” vulnerability discovered in 2020. Hackers could exploit flaws to jump from the smart bulb to the home network. Once inside, they could potentially access sensitive data or take control of other smart gadgets.
To stay safe, always update your smart devices’ firmware and keep them on a separate network from your primary devices.
3. Barcode Scanners
Believe it or not, barcode scanners can become vectors for malware, too. In one case known as “Zombie Zero,” attackers embedded malware into the firmware of barcode scanners before they even left the factory.
Once these compromised scanners were used in warehouses, they infected connected systems, allowing hackers to spy on corporate networks and steal data. This is a prime example of a supply chain attack where infected hardware is shipped directly from the manufacturer.
Always check for firmware updates and run security scans even on seemingly simple devices like scanners.
4. Smart Coffee Maker
Who knew your morning coffee could be a security risk? Some high-tech coffee makers come with Wi-Fi connectivity and smartphone control, making them vulnerable to attacks. Researchers have shown that smart coffee machines can be hacked to not only disrupt their functions but also act as a gateway into your home network.
One security researcher demonstrated how they could make the coffee maker constantly boil water or refuse to brew until a ransom was paid; a quirky but serious take on ransomware. However, a real-world cyber attack on a coffee machine has already happened. It happened in July 2017 when a coffee machine was compromised to infect computer devices at a factory company that has multiple petrochemical factories making chemicals in Europe.
5. Traffic Lights
Smart traffic lights, essential for managing city traffic, are vulnerable to cyberattacks. Hackers can exploit weak security protocols or outdated software to manipulate signals, causing chaos on the roads. In some cases, malware can alter light patterns or disable systems entirely, leading to accidents or gridlock. Researchers have demonstrated how vulnerabilities in communication protocols allow control over signals.
How to Stay Safe
- Keep Firmware Updated: No matter how harmless a device seems, make sure its software is up to date.
- Segment Your Network: Keep IoT devices on a separate network from your primary devices.
- Use Strong Passwords: Set unique, complex passwords for each device.
- Monitor Network Activity: Regularly check which devices are connected to your network.
It’s crazy to think that everyday gadgets, from headphones to coffee makers, can become cybersecurity nightmares. However, that’s just how the world of cybersecurity works – make security part of your daily routine.
