Introduction The firmware is the embedded software that controls the basic functioning of electronic devices, from routers and IP cameras to smart home appliances and industrial systems. Unlike traditional software, firmware operates directly on hardware, making it a critical target in terms of security, functionality, and privacy. Firmware analysis involves examining this embedded software to understand its internal workings, detect potential vulnerabilities, identify backdoors, and in some cases modify or extract relevant information. This type of analysis is particularly relevant in security audits, forensic investigations, reverse engineering, or exploit development. ...

Introduction️ DMR (Digital Mobile Radio) is a digital radio standard developed by the ETSI (European Telecommunications Standards Institute), designed to replace analog radio systems and offer more efficient communications. It operates in TDMA (Time Division Multiple Access) with two time slots within a 12.5 kHz channel, allowing for simultaneous transmissions on the same frequency. It allows additional services beyond voice transmission, such as data sending, like text messages or location reports of terminals. Around voice, it allows both individual calls similar to mobile phone calls and group calls, where registered terminals can participate.️ ...
