Side-Channel Attacks on Mobile and IoT what they are, why they matter, and how to defend against them
Side-channel attacks are the ugly truth most developers don’t want to face: they extract secrets without breaking crypto math or getting privileged access — by observing physical or microarchitectural side effects (timing, power consumption, EM emissions, cache behavior, sensors, etc.). On constrained devices like phones and IoT nodes this problem is worse because hardware…

Bluetooth Low Energy (BLE) Attacks and Mobile App Protection
1. Understanding BLE and Its Security Exposure Bluetooth Low Energy (BLE) has become the foundation for modern wireless communication between IoT devices, wearables, and mobile applications. Its low power consumption and fast connection establishment make it ideal for health sensors, smart locks, and tracking devices.However, this convenience introduces a hidden risk: BLE communications often…
