Can Smart Doorbells Be Hacked?

Here are some common ways hackers can breach Nest Doorbell’s security and spy on the homeowner’s property.

  • Executing phishing attacks to steal credentials: Even if you use a strong password, the security of your Nest Doorbell can be jeopardized by hackers stealing your password through phishing attacks. Hackers will send phishing messages, making you believe that your Google Home devices need security updates and require you to enter the password with the aim of using it to view your Hello footage or recordings.
  • Hacking home network/Wi-Fi router: Universal Plug and Play (UPnP) and port forwarding feature in Nest Hello Doorbell’s settings leaves it vulnerable to cyber-attacks. Hackers take advantage of UPnP and open ports to hijack Wi-Fi routers and gain access to the password.

  • Hacking connected devices: Pairing your Nest doorbell to Google Home smart home devices also leaves your doorbell vulnerable for hackers to hack. For example, they can penetrate Google Assistant and use voice-command to access your recordings or watch your surroundings. 
  • Installing malicious firmware: Hackers can gain unauthorized access to Nest Doorbell by installing malicious firmware to your home network or via USB port or by exploiting security flaws not yet publicly disclosed. 
  • Using laser-powered voice commands: Hackers can gain access to your doorbell by using laser light commands on voice-activated Google Home devices.
