On day 92 of my 100 days of cybersecurity challenge, I explored the HackRF One tool, a versatile software-defined radio (SDR) device. This deepened my understanding of radio frequency (RF) technology and its applications in cybersecurity, including wireless network analysis, signal monitoring, and radio frequency testing. HackRF One from Great Scott Gadgets is a Software Defined Radio peripheral capable of transmission or reception of radio signals from 1 MHz to 6 GHz. Designed to enable test and development of modern and next generation radio technologies, HackRF One is an open source hardware platform that can be used as a USB peripheral or programmed for stand-alone operation ➡ 1 MHz to 6 GHz operating frequency ➡ half-duplex transceiver ➡ up to 20 million samples per second ➡ 8-bit quadrature samples (8-bit I and 8-bit Q) ➡ compatible with GNU Radio, SDR#, and more ➡ software-configurable RX and TX gain and baseband filter ➡ software-controlled antenna port power (50 mA at 3.3 V) ➡ SMA female antenna connector ➡ SMA female clock input and output for synchronization ➡ convenient buttons for programming ➡ internal pin headers for expansion ➡ Hi-Speed USB 2.0 ➡ USB-powered ➡ open source hardware #Cybersecurity #InfoSec #Security #Hacking #InfoSecurity #DataProtection #CyberThreats #NetworkSecurity #CyberAware #CyberSkill #CyberEducation #HackRF

#Day44 of #100daychallenge Day 44: Bus Pirate Today’s tool is the Bus Pirate, an incredibly versatile device for prototyping and debugging embedded hardware. Designed to communicate with electronic components, Bus Pirate supports protocols like I2C, SPI, and UART, allowing cybersecurity professionals to analyze communication between chips, sensors, and other peripherals. Bus Pirate works as an interface between the computer and hardware, enabling signal generation and reading. This makes it ideal for testing and identifying vulnerabilities in embedded systems. With built-in features like voltage measurement, Bus Pirate allows users to probe pins, identify unknown chips, and communicate directly with circuits without dedicated connectors. This tool simplifies hardware hacking by translating complex communication into readable output, empowering users to work with embedded protocols without extensive setup or protocol-specific hardware. #Cybersecurity #BusPirate #EmbeddedSecurity #HardwareHacking #Prototyping

Part 2: I was once told in the early 80’s, that I didn’t know anything about microprocessors. (see story below) Ironically, Dick Gasperini’s concept of “Front Panel Analysis” still works with Cyber, but all the knobs, dials and displays have moved… Our generation might be old, but most of us know how to improvise, adapt and overcome… and then there are the empaths… You don’t know, what you don’t know… Photo: Digital Troubleshooting was the precursor to the microprocessor workshops.
