Ever wanted to spoof a restaurant’s pager system? How about use an airport’s Primary Surveillance RADAR to build your own bistatic RADAR system and track moving objects?
What sorts of RF transactions take place in RFID systems, such as toll booths, building security and vehicular keyless entry? Then there’s ‘printing’ steganographic images onto the radio spectrum… Wireless systems, and their radio signals, are everywhere: consumer, corporate, government, amateur – widely deployed and often vulnerable.
If you have ever wondered what sort of information is buzzing around you, this talk will introduce how you can dominate the RF spectrum by ‘blindly’ analysing any signal, and then begin reverse engineering it from the physical layer up. I will demonstrate how these techniques can be applied to dissect and hack RF communications systems, such as those above, using open source software and cheap radio hardware.
In addition, I’ll show how long-term radio data gathering can be used to crack poorly-implemented encryption schemes, such as the Radio Data Service’s Traffic Message Channel.If you have any SDR equipment, bring it along!
Bio: A software engineer by training, Balint is a perpetual hacker, and the guy behind spench.net. His passion is extracting interesting information from lesser-known data sources and visualizing them in novel ways. Lately, he has become obsessed with Software Defined Radio and all that can be decoded from the ether. When not receiving electromagnetic radiation, he likes to develop interactive web apps for presenting spatial data. Originally from Australia, he moved to the United States in 2012 to pursue his love of SDR.
