Your Smart TV, Car, and Smart Home Can Be Hacked Too — Understanding IoT Security Risks

Most people understand that computers, smartphones, and online accounts can be hacked. What many still underestimate is that modern smart devices inside homes, offices, vehicles, and buildings are also connected to the internet — and many of them can become cybersecurity targets.

Smart TVs, connected cars, surveillance cameras, smart locks, voice assistants, thermostats, industrial sensors, and even entire smart homes operate through internet-connected systems commonly known as IoT devices.

As the number of connected devices continues growing globally, cybersecurity risks increasingly extend far beyond laptops and mobile phones into physical infrastructure, transportation systems, buildings, and everyday environments.

What Is IoT?

IoT stands for Internet of Things. It refers to physical devices connected to the internet that collect, exchange, process, or transmit data continuously.

These devices often include embedded software, sensors, cloud connectivity, APIs, wireless communication systems, and remote management capabilities.

Common IoT devices include:

• Smart TVs

• Smart home systems

• Security cameras

• Smart locks

• Voice assistants

• Connected vehicles

• Smart lighting systems

• Industrial monitoring sensors

• Medical monitoring devices

Modern IoT environments now exist across homes, businesses, governments, transportation systems, factories, healthcare infrastructure, and smart cities.

Yes, Smart TVs Can Be Hacked

Many smart TVs contain microphones, cameras, application platforms, internet browsers, wireless connectivity systems, cloud synchronization features, and downloadable applications.

Vulnerabilities inside outdated firmware, insecure applications, weak authentication systems, or compromised network environments can potentially allow attackers to:

• Spy through connected microphones or cameras

• Monitor viewing behavior

• Install malicious applications

• Gain network access to other devices

• Exploit weak home network security

Many users forget that smart TVs now operate similarly to internet-connected computers.

Connected Cars Are Increasingly Digital Systems

Modern vehicles contain highly advanced digital systems controlling navigation, communication, braking assistance, entertainment, diagnostics, cloud connectivity, remote updates, GPS systems, and internal operational sensors.

Connected cars communicate continuously with mobile applications, manufacturer platforms, APIs, wireless systems, and cloud infrastructure.

Security researchers have demonstrated that poorly secured automotive systems may expose vulnerabilities capable of affecting:

• Vehicle tracking

• Remote unlocking systems

• Engine diagnostics

• Internal communication systems

• Telematics infrastructure

Automotive cybersecurity has therefore become a major global security focus as transportation systems become increasingly software-driven.

Smart Homes Create Expanded Attack Surfaces

Smart homes combine multiple connected systems into centralized digital environments controlling lighting, cameras, locks, alarms, appliances, climate systems, entertainment systems, and access controls.

If these systems are poorly secured, attackers may potentially gain unauthorized access to:

• Security cameras

• Smart locks

• Alarm systems

• Internal network devices

• Home automation systems

• Voice assistants

The more connected devices inside an environment, the larger the operational attack surface becomes.

Why IoT Devices Are Frequently Vulnerable

Many IoT devices prioritize convenience, low cost, and rapid deployment over long-term cybersecurity resilience.

Common security weaknesses include:

• Weak default passwords

• Outdated firmware

• Poor encryption standards

• Insecure APIs

• Limited update support

• Weak authentication systems

• Misconfigured cloud connectivity

Attackers often target the weakest connected device because compromising one vulnerable system may provide entry into larger networks or operational environments.

How to Stay Safe in an IoT Environment

Basic cybersecurity hygiene significantly reduces exposure to IoT-related threats.

Recommended protection measures include:

• Change all default passwords immediately

• Enable multi-factor authentication where possible

• Keep firmware and software updated

• Disable unnecessary remote access features

• Separate IoT devices onto isolated networks when possible

• Avoid installing untrusted applications

• Purchase devices from trusted manufacturers

• Monitor connected device activity continuously

Businesses and governments operating large IoT environments require much more advanced monitoring, visibility, and operational intelligence systems.

IoT Security Requires Continuous Monitoring

Traditional cybersecurity models focused mainly on protecting computers and network perimeters. Modern IoT ecosystems now involve highly distributed environments filled with constantly communicating devices, sensors, APIs, applications, and cloud systems.

This requires continuous operational visibility, application-layer intelligence, AI-powered anomaly detection, behavioral analytics, and real-time infrastructure monitoring capable of identifying suspicious device behavior quickly.

Modern attacks increasingly move through connected ecosystems rather than targeting isolated systems directly.
