Explainer-Could hackers get inside my fridge?

In 2015, researchers showcased a method to infiltrate a Samsung smart refrigerator at a Las Vegas hacking convention, enabling them to eavesdrop on the device's internet traffic. Typically, cybercriminals seek to pilfer data, disrupt services, or utilize connected devices as stepping stones to larger networks. Household devices frequently targeted by hackers include security cameras, video doorbells, alarm systems, smart locks, thermostats, and smart appliances like refrigerators, ovens, and washing machines. Even certain toothbrushes now boast internet connectivity.

Most cyber assaults on linked devices originate from routers rather than appliances themselves. The surge in internet-enabled products, once purely mechanical, has amplified the attack surface. Once inside a device, hackers can either extract information or seize control. Affected devices may display home interiors, capture audio, or expose network traffic.

By commandeering a device, attackers can initiate or halt its functions, modify settings, or bar users from their accounts. Compromised thermostats could interfere with heating, while infiltrated freezers or refrigerators could disrupt temperature controls. In grave instances, malicious actors may leverage weak devices to infiltrate other systems on the same network or pilfer personal details from associated online accounts.

Cybersecurity analysts have consistently unearthed susceptibilities in connected vehicles. In 2015, researchers managed to remotely manipulate a moving Jeep via its internet-linked entertainment system, prompting a recall of around 1.4 million vehicles and the issuance of software patches. Nearly a decade later, researchers disclosed a loophole that facilitated tracking, unlocking, and starting certain Kia vehicles using merely a license plate number.

The researchers asserted they promptly reported the vulnerabilities to Kia, which remedied them within months, and there was no evidence of real-world exploitation. Contemporary vehicles and aircraft incorporate robust safety and backup mechanisms, but critical infrastructure such as power and water networks often possess multiple layers of security, surveillance, and regulation—features absent in consumer devices.

However, this does not imply they are impervious to cyber attacks; instead, they typically serve as less appealing targets for hackers compared to household appliances linked to home Wi-Fi networks.
