Cybersecurity expert John Joyce emphasizes the vulnerabilities of mobile devices, noting that many users mistakenly believe their smartphones are secure. He highlights that smartphones often serve as primary computing devices, storing sensitive personal information, which makes them attractive targets for cybercriminals. Joyce advises users to look for signs of compromise, such as device slowdowns or unusual app behavior, and to keep their devices updated with the latest operating systems and security patches to reduce risks. He recommends using a Virtual Private Network (VPN) when on public Wi-Fi and suggests utilizing security apps like Norton and TotalAV for additional protection. Joyce also points individuals to Cirrus Technology Consultants' online resources for further information on mobile cybersecurity.
