Reverse engineering a Verisure wireless alarm

Here’s an informative two-part series of posts over at FunOverIP detailing how to reverse engineer a Verisure wireless alarm.

Part 1 details the beginning steps such as finding the modules radio frequency and modulation type, analyzing the chipset datasheet and using GNU Radio. Part 2 covers more complex topics including firmware extraction from an alarm module and analysis of crypto keys.

Good coverage of an interesting use of SDR and related tools.

  1. I’d love to get into SDR, but all the different hardware and software makes it a bit difficult to get started on..

    Anyone know what the difference between the HackRF, AIRSPY , PortableSDR(PSDR), RTL2832U dongles (R820T/E4000), Myriad RF / Novena, etc?

    Do they all support the same software (SDR#) or are there different software choices based on the hardware platform?

    I’d like to capture my rf remote light switch and mimic the signal using a modified beagle bone! I still have a lot to learn*, as I’m wondering what else is possible with an sdr dongle… listening to am/fm radio?

    1. I’m sure there are tons of good sites that can tell you lots about SDR (maybe try Wikipedia for a start), but I do know of a number of articles in the Australian publication Silicon Chip magazine over 2013 and 2014 and they might be a good starting place too. You do need to either buy the print copy or pay for the article on-line, but you can get a preview with many articles.
