So many reasons to be able to do this, and I hope the title is descriptive enough. I will admit that most people who want to do this are people who are on a corporate environment that is blocking ssh traffic…. but my purposes are a little darker….like usual (wink). Sometimes ssh is blocked, some times you want to hide your ssh traffic….in my case I wanted a way to hide my ssh traffic from my raspberry pi drop boxes. When I do a pen test engagement and I physically break in I drop off a raspberry pi and the more stealthy I can have it be, as I have it perform tasks, the more dangerous and longer I can leverage it to help identify the vulnerabilities I need to find. Yes, you can also use this method to circumvent corporate firewalls and security systems that are blocking ssh traffic, […]
My hobby time this week has been consumed with a project for my daughter. Her “Activity Days” girls are doing a Pinewood Derby with the Cub Scouts in our ward so I built her a car. Originally she wanted a puppy car….and she and I worked on a few designs but when we found out the race is this week I had to look for something that was a little less time consuming…. so we built one after her second favorite thing…Hershey Chocolate bars!
I have a few theories on how to circumvent the RCR-REX request to exit sensors. Cloud of moisture moving towards/away from sensor along with can of air to trip PIR; long straw/hose with can of air? radio jamming or some other method using the HackRF – it looks like the operating frequency for the RCR-REX-W is 5.8Ghz….. Tinfoil to reflect the 5.8Ghz microwave signals….or an unbrella that has reflection/obsorbsion of the radio waves…. Push rod with pop-up? Or drop down object like unbrella – might trigger both sensors at the same time cover the RCR sensor with tinfoil or something repeater of radio waves, the delay could simulate distance? It uses the doppler method so as an object gets closer the waves will be reflected back at a quicker rate, my understanding is it does not do a signal on that wave just a specific frequency could still try the small […]
Sometimes you just need to push yourself to finish a project….it is a fun project there are just other things I want to work on too…. I remember seeing people around me not finishing projects growing up, and even friends of mine, with partial projects laying all over the place. Ok, it is me, I am notorious for this… A while back I shared some details about a project I started that simulates a Disneyland Holocron. They use RFID inside their Kyber Crystals to change colors of the Light Sabers and the Holocrons. Well, now I have the electronics all together to change light colors based on the different RFID fobs or Kyber Crystals so now to wrap things up I need to put all the electronics in something that looks like a StarWars Holocron… I have a 3D printer, actually had two, so I converted one into a laser […]
Well… all this RFID stuff wasn’t all just because I was trying to be a maker person…. nope, there was still the hacker/pen tester in me that was driving all this RFID shenanigans. I built something, it was actually something I built before I made the RFID holocron raspberry Pi RDM6300 thing…. First I want to give credit where credit is due, I basically used the notes from this wonderful info sec individual named Alex Dib and his post on the RFID Thief v2.0 – Here another great post Here and it is all based on the Wiegotcha code found Here. Parts:– Raspberry Pi 3 – I also made a variation using a Raspberry Pi Zero W but more on that latter – I also got one working with a Raspberry Pi 2 but needed a USB wifi dongle to go into AP mode– HID MaxiProx 5375 – got mine […]
Well…. You can’t blame me and the other people like me, if you make cool toy that has a cool technology you can’t blame us for checking it out and figuring it out….. Well, I took my previous project using a RDM6300 and a raspberry Pi and I added some 5050 LED strip lights…..I planed on making the lights do something different based on the RFID that was detected….so I needed some EM4100 RFIDs to read and mess with….so I found certain Kyber Crystals from the big D place just happened to have EM4305 RFID chips in them that could be read as EM4100s. I did similar wiring to this page here. But I specifically used GPIO pins 23, 24, 25 to control the RGB of the 5050 led strip. Then I hacked up this python code here (I borrowed some of it from the link in the last post […]
ok, we are going to play with a little RFID…. I have messed a lot with RFID access cards, IOProx, HID, etc…. but not much with the EM4100 and EM4305 so that is what I am playing with right now. I will probably write some notes up on HID and IOProx later…. Parts:– Raspberry Pi Zero W – with SD Card obviously– RDM6300 module and antenne– Logic Level Shifter– jumper wires Start with a headless install of a Raspberry Pi – like from these notes here Now you need to wire up this stuff…..first the pinouts Now we gotta wire it all together…here is my poor attempt at portraying that…. I did use this page for some help, but it is a little old – here. You now need to enable/disable some stuff on the regular raspian image….first run “sudo raspi-config”– Select “Interfacing Options” this was number 5 for me– […]
