  • Unsecured Networks: Connecting smart devices to an unsecured Wi‑Fi network can expose them to cyberattacks.
  • Software Vulnerabilities: Outdated firmware or poorly coded software can leave devices open to exploitation.
  • Interconnected Devices: Once one device is compromised, hackers can potentially access other devices connected to the same network.

For example, a hacked smart camera might provide a live feed of your home, while an exploited smart speaker could record private conversations. These scenarios illustrate the serious privacy implications of unsecured smart home devices.

2.3 The Role of Third-Party Data Sharing

Many smart home manufacturers partner with third-party companies to analyze user data and deliver targeted advertisements. This practice can result in:

  • Personalized Advertising: Your data is used to create detailed profiles that fuel personalized marketing campaigns.
  • Data Monetization: Companies may sell your anonymized data to other businesses, which can then use it for various commercial purposes.
  • Lack of Transparency: Often, users are not fully aware of how much data is being shared or who has access to it.
