Spyware is a type of malicious software – or malware – that is installed on a computing device without the end user’s knowledge. It invades the device, steals sensitive information and internet usage data, and relays it to advertisers, data firms or external users.
Mobile spyware is dangerous because it can be transferred through Short Message Service or Multimedia Messaging Service text messages and typically does not require user interaction to execute commands. When a smartphone or tablet gets infected with mobile spyware that is sideloaded with a third-party app, the phone’s camera and microphone can be used to spy on nearby activity, record phone calls, and log browsing activity and keystrokes. The device owner’s location can also be monitored through the Global Positioning System (GPS) or the mobile computing device’s accelerometer.
How do you prevent spyware?
Maintaining strict cybersecurity practices is the best way to prevent spyware. Some best practices include the following:
• only downloading software from trusted sources
• reading all disclosures when installing software
• avoiding interactions with pop-up ads
• staying current with updates and patches for browser, operating system (OS) and applications
• not opening email attachments or clicking on links from unknown senders
• using a trusted antivirus application to find suspicious programs and remove them
• enabling two-factor authentication (2FA) whenever possible
