Overview

• Automatic Wi-Fi connections to open or known networks can enable man-in-the-middle attacks through fake hotspots that harvest passwords and financial details.
• Leaving Bluetooth permanently enabled makes devices discoverable and vulnerable to bluebugging attacks that can intercept calls, messages or hijack functions.
• Continuously active GPS services allow apps and third parties to track user movements and collect location data without explicit need.
• Security experts recommend turning off Wi-Fi and Bluetooth when idle, setting devices to non-discoverable and restricting GPS permissions to active app sessions.
• Enhancing cyber-hygiene with VPN use in public spaces and keeping operating systems and security tools up to date further safeguards mobile data.
