Now we are going to do a Nmap TCP SYN port scan to check all opened ports. ...

Introduction Modulation by frequency shift (FSK, Frequency Shift Keying) is a digital modulation technique where binary information is transmitted by varying the frequency of a carrier between two or more discrete values. In its simplest form, 2-FSK, a bit 0 is represented with a specific frequency (f0) and a bit 1 with another (f1). This technique is widely used in low-speed wireless communications, such as remote controls, telemetry systems, RFID, and IoT devices. ...

Introduction The Flipper Zero is a multifunction device for hacking, security testing and radio frequency protocol exploration. One of its most highlighted features is the ability to transmit and receive SubGHz signals, using the Texas Instruments CC1101 chip, a programmable low-power RF transmitter. SubGHz refers to the range of radio frequencies below 1 GHz (typically between 300 MHz and 928 MHz, depending on the region). These frequencies are used by devices such as remote garage door controls or wireless sensors (temperature, movement, alarms). ...

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. ...
