Introduction️ Nordic nRF51 is a series of system-on-a-chip (SoC) developed by Nordic Semiconductor. These chips are designed specifically for low power and low energy applications in the field of wireless connectivity. The nRF51 series includes several models, such as the nRF51822 and the nRF51802, among others.️ These chips are widely used in low-power devices, such as wearables, IoT sensors (Internet of Things), health devices, and other devices that require efficient connectivity and minimal energy consumption. In the case that we need to perform a reverse engineering analysis on some of these devices it will be necessary to obtain a copy of the firmware from the chip itself of the device.️ ...

Introduction️ Remote controls by infrared (IR) are electronic devices that use infrared signals to communicate with other electronic devices, such as televisions or air conditioners. The basic operation of an IR remote control is based on the emission of infrared signals from the remote towards an infrared receiver in the device being controlled.️ These signals contain specific codes that are interpreted by the receiving device, causing the corresponding action to be executed, such as turning the device on and off, changing channels, or adjusting volume. The infrared signals generated by the IR LED are modulated, meaning the light intensity is periodically modified according to a specific pattern. This modulation pattern is unique for each button or function on the remote control.️ ...

Introduction️ One of the phases of dynamic analysis of Android applications is the interception of connections made by the application to remote servers. In the case that they use the HTTP protocol can be easily intercepted and manipulated with a proxy server since the protocol does not use encryption. But in the case that it uses the HTTPS protocol we will need to install an SSL certificate from a Certification Authority on our device since the connection will be encrypted with this one. Additionally, some applications use the technique of SSL Pinning, which consists in trusting only certain embedded certificates in the application.️ ...
