Ray Felch // Disclaimer When using an FM transmitter, do not modify the intended operation of the module by amplifying the transmitted signal. Also, be sure that attaching an FM high gain antenna will NOT be transmitting outside the legal range for RF emissions. When transmitting any data, be sure you do not accidentally break any laws by illegally […]
Ray Felch // Overview Infrared technology has been around for a very long time and is a wireless technology used in devices that convey data by way of Infrared radiation. Infrared is electromagnetic radiation (EMR) with a wavelength just beyond the visible light spectrum. Inasmuch, Infrared can not be seen by the naked eye, Fun fact: Although […]
Ray Felch // Introduction While packing up my KeyWe Smart Lock accessories, and after wrapping up my research and two previous blogs “Reverse Engineering a Smart Lock” and “Machine-in-the-Middle BLE Attack”, I came across a couple of KeyWe RFID tags. Although I was somewhat already familiar with RFID (Radio Frequency ID) technology, I decided this […]
Ray Felch // Introduction Continuing with my ongoing Smart Lock attack research (see blog Reverse Engineering a Smart Lock), I decided to move my focus to a different type of attack technique, namely a relay attack. The relay attack is a form of MitM attack, not to be confused with the more well-known replay attack. […]
Ray Felch // INTRODUCTION Recently I was afforded the opportunity to research the findings of a well-known security firm (F-Secure), who had discovered a vulnerability in the Guardtec KeyWe Smart Lock. The F-Secure people found that due to a design flaw, an attacker could intercept and decrypt traffic coming from a legitimate owner of the […]
Ray Felch // Introduction: After completing and documenting my recent research into keystroke injections (Executing Keyboard Injection Attacks), I was very much interested in learning the in-depth technical aspects of the tools and scripts I used (created by various authors and security research professionals). In particular, I was interested in creating my own software/hardware implementation […]
Ray Felch // Preface: Following the work of the Bastille Research Group (See: https://github.com/BastilleResearch/mousejack), I was interested in knowing if these (keyboard injection) vulnerabilities were still valid. To my surprise, I was able to duplicate the attack on an inexpensive Logitech keyboard that I already had in my possession. This keyboard (Logitech K400r) is still […]
Rick Wisser // Note: This blog will also be a lab for any of the upcoming Wild West Hackin’ Fest Conferences. During a recent engagement, I came across an issue. The issue I encountered was that the SPI chip I was trying to dump the firmware off of was a 1.8v chip. This would not […]
Ray Felch // SOFTWARE DEFINED RADIO: RF Signal Replay Techniques Disclaimer: Be sure to use a faraday bag or cage before transmitting any data so you don’t accidentally break any laws by illegally transmitting on regulated frequencies. Additionally, intercepting and decrypting someone else’s data is illegal, so be careful when researching your traffic. Preface: Recently, […]
