SDR TOOLKIT BENDS weather condition station TO HACKER’S WHIMS
We most likely don’t have to tell most Hackaday visitors why the present wave of low-cost software application defined radios (SDRs) are such a huge offer for hackers looking to check out the wide world of wireless signals. however if you do requirement a refresher as to what type of SDR hardware as well as software application should be in your bag of tricks, then this fantastically detailed account from [RK] about exactly how he hacked his La Crosse WS-9611U-IT weather condition station is a perfect example.
Looking to clean up his radio hacking skills, [RK] set out to utilize the ADALM-PLUTO software application defined radio from Analog gadgets to intercept signals between the La Crosse base station as well as its assorted wireless sensors. He notes that a $20 USD RTL-SDR dongle might do just also if you only wished to receive, however since his ultimate goal was to spoof a temperature sensor as well as introduce spurious data into the system, he needed an SDR that had transmit capabilities.
No matter your hardware, universal Radio Hacker (URH) is the software application that’s going to be doing the heavy lifting. In his write-up, [RK] walks the visitor with every step needed to find, capture, as well as ultimately decode the transmissions coming from a TX29U wireless temperature sensor. While the specifics will naturally modification a bit depending upon the gadget you’re personally looking to listen in on, the general workflow is going to be more or less the same.
In the end, [RK] is not only able to get the data coming from the wireless sensors, however he can transmit his own spoofed data that the weather condition station accepts as legitimate. getting there took some additional effort, as he had to figure out the appropriate CRC algorithm being used. however as luck would have it, he discovered a Hackaday article from a couple years back that talked about doing precisely that, which assist put him on the right path. now he can make the bit animated guy on the weather condition station’s screen don a winter coat in the middle of July. inspect out the video below for a presentation of this specific piece of radio prestidigitation.
Demodulating the waveform in universal Radio Hacker.
While we commonly see the power of tools like URH brought up in talks, nothing rather beats complying with together with a step-by-step account of exactly how somebody utilized software application as well as hardware from the contemporary hacker’s toolkit to accomplish their goals. If reading this publish doesn’t make you want to lastly pull the trigger on a affordable RTL-SDR as well as begin cruising the airwaves, perhaps nothing will.
